After Free | Referencing memory after it has been freed can cause a program to crash, use unexpected values, or execute code. |
The use of previously-freed memory can have any number of adverse consequences, ranging from the corruption of valid data to the execution of arbitrary code, depending on the instantiation and timing of the flaw. The simplest way data corruption may occur involves the system's reuse of the freed memory. Use-after-free errors have two common and sometimes overlapping causes:
Error conditions and other exceptional circumstances.
Confusion over which part of the program is responsible for freeing the memory.
In this scenario, the memory in question is allocated to another pointer validly at some point after it has been freed. The original pointer to the freed memory is used again and points to somewhere within the new allocation. As the data is changed, it corrupts the validly used memory; this induces undefined behavior in the process.
If the newly allocated data chances to hold a class, in C++ for example, various function pointers may be scattered within the heap data. If one of these function pointers is overwritten with an address to valid shellcode, execution of arbitrary code can be achieved.
| https://cwe.mitre.org/data/definitions/416.html | 0 | Nick Wellnhofer | 2022-02-08 03:29:24+01:00 | [CVE-2022-23308] Use-after-free of ID and IDREF attributes
If a document is parsed with XML_PARSE_DTDVALID and without
XML_PARSE_NOENT, the value of ID attributes has to be normalized after
potentially expanding entities in xmlRemoveID. Otherwise, later calls
to xmlGetID can return a pointer to previously freed memory.
ID attributes which are empty or contain only whitespace after
entity expansion are affected in a similar way. This is fixed by
not storing such attributes in the ID table.
The test to detect streaming mode when validating against a DTD was
broken. In connection with the defects above, this could result in a
use-after-free when using the xmlReader interface with validation.
Fix detection of streaming mode to avoid similar issues. (This changes
the expected result of a test case. But as far as I can tell, using the
XML reader with XIncludes referencing the root document never worked
properly, anyway.)
All of these issues can result in denial of service. Using xmlReader
with validation could result in disclosure of memory via the error
channel, typically stderr. The security impact of xmlGetID returning
a pointer to freed memory depends on the application. The typical use
case of calling xmlGetID on an unmodified document is not affected. | 652dd12a858989b14eed4e84e453059cd3ba340e | False | GNOME/libxml2 | Read-only mirror of https://gitlab.gnome.org/GNOME/libxml2 | 2012-06-03 12:37:38 | 2022-08-26 15:36:45 | https://gitlab.gnome.org/GNOME/libxml2 | GNOME | 395.0 | 295.0 | xmlAddRef | xmlAddRef( xmlValidCtxtPtr ctxt , xmlDocPtr doc , const xmlChar * value , xmlAttrPtr attr) | ['ctxt', 'doc', 'value', 'attr'] | xmlAddRef(xmlValidCtxtPtr ctxt, xmlDocPtr doc, const xmlChar *value,

After Free | Referencing memory after it has been freed can cause a program to crash, use unexpected values, or execute code. |
The use of previously-freed memory can have any number of adverse consequences, ranging from the corruption of valid data to the execution of arbitrary code, depending on the instantiation and timing of the flaw. The simplest way data corruption may occur involves the system's reuse of the freed memory. Use-after-free errors have two common and sometimes overlapping causes:
Error conditions and other exceptional circumstances.
Confusion over which part of the program is responsible for freeing the memory.
In this scenario, the memory in question is allocated to another pointer validly at some point after it has been freed. The original pointer to the freed memory is used again and points to somewhere within the new allocation. As the data is changed, it corrupts the validly used memory; this induces undefined behavior in the process.
If the newly allocated data chances to hold a class, in C++ for example, various function pointers may be scattered within the heap data. If one of these function pointers is overwritten with an address to valid shellcode, execution of arbitrary code can be achieved.

If a document is parsed with XML_PARSE_DTDVALID and without
XML_PARSE_NOENT, the value of ID attributes has to be normalized after
potentially expanding entities in xmlRemoveID. Otherwise, later calls
to xmlGetID can return a pointer to previously freed memory.
ID attributes which are empty or contain only whitespace after
entity expansion are affected in a similar way. This is fixed by
not storing such attributes in the ID table.
The test to detect streaming mode when validating against a DTD was
broken. In connection with the defects above, this could result in a
use-after-free when using the xmlReader interface with validation.
Fix detection of streaming mode to avoid similar issues. (This changes
the expected result of a test case. But as far as I can tell, using the
XML reader with XIncludes referencing the root document never worked
properly, anyway.)
All of these issues can result in denial of service. Using xmlReader
with validation could result in disclosure of memory via the error
channel, typically stderr. The security impact of xmlGetID returning
a pointer to freed memory depends on the application. The typical use
case of calling xmlGetID on an unmodified document is not affected. | 652dd12a858989b14eed4e84e453059cd3ba340e | False | GNOME/libxml2 | Read-only mirror of https://gitlab.gnome.org/GNOME/libxml2 | 2012-06-03 12:37:38 | 2022-08-26 15:36:45 | https://gitlab.gnome.org/GNOME/libxml2 | GNOME | 395.0 | 295.0 | xmlValidCtxtNormalizeAttributeValue | xmlValidCtxtNormalizeAttributeValue( xmlValidCtxtPtr ctxt , xmlDocPtr doc , xmlNodePtr elem , const xmlChar * name , const xmlChar * value) | ['ctxt', 'doc', 'elem', 'name', 'value'] | xmlValidCtxtNormalizeAttributeValue(xmlValidCtxtPtr ctxt, xmlDocPtr doc,

After Free | Referencing memory after it has been freed can cause a program to crash, use unexpected values, or execute code. |
The use of previously-freed memory can have any number of adverse consequences, ranging from the corruption of valid data to the execution of arbitrary code, depending on the instantiation and timing of the flaw. The simplest way data corruption may occur involves the system's reuse of the freed memory. Use-after-free errors have two common and sometimes overlapping causes:
Error conditions and other exceptional circumstances.
Confusion over which part of the program is responsible for freeing the memory.
In this scenario, the memory in question is allocated to another pointer validly at some point after it has been freed. The original pointer to the freed memory is used again and points to somewhere within the new allocation. As the data is changed, it corrupts the validly used memory; this induces undefined behavior in the process.
If the newly allocated data chances to hold a class, in C++ for example, various function pointers may be scattered within the heap data. If one of these function pointers is overwritten with an address to valid shellcode, execution of arbitrary code can be achieved.

If a document is parsed with XML_PARSE_DTDVALID and without
XML_PARSE_NOENT, the value of ID attributes has to be normalized after
potentially expanding entities in xmlRemoveID. Otherwise, later calls
to xmlGetID can return a pointer to previously freed memory.
ID attributes which are empty or contain only whitespace after
entity expansion are affected in a similar way. This is fixed by
not storing such attributes in the ID table.
The test to detect streaming mode when validating against a DTD was
broken. In connection with the defects above, this could result in a
use-after-free when using the xmlReader interface with validation.
Fix detection of streaming mode to avoid similar issues. (This changes
the expected result of a test case. But as far as I can tell, using the
XML reader with XIncludes referencing the root document never worked
properly, anyway.)
All of these issues can result in denial of service. Using xmlReader
with validation could result in disclosure of memory via the error
channel, typically stderr. The security impact of xmlGetID returning
a pointer to freed memory depends on the application. The typical use
case of calling xmlGetID on an unmodified document is not affected. | 652dd12a858989b14eed4e84e453059cd3ba340e | False | GNOME/libxml2 | Read-only mirror of https://gitlab.gnome.org/GNOME/libxml2 | 2012-06-03 12:37:38 | 2022-08-26 15:36:45 | https://gitlab.gnome.org/GNOME/libxml2 | GNOME | 395.0 | 295.0 | xmlValidNormalizeAttributeValue | xmlValidNormalizeAttributeValue( xmlDocPtr doc , xmlNodePtr elem , const xmlChar * name , const xmlChar * value) | ['doc', 'elem', 'name', 'value'] | xmlValidNormalizeAttributeValue(xmlDocPtr doc, xmlNodePtr elem,

A crash can occur when the code reads a variable amount of data and assumes that a sentinel exists to stop the read operation, such as a NUL in a string. The expected sentinel might not be located in the out-of-bounds memory, causing excessive data to be read, leading to a segmentation fault or a buffer overflow. The software may modify an index or perform pointer arithmetic that references a memory location that is outside of the boundaries of the buffer. A subsequent read operation then produces undefined or unexpected results.

Limited resources include memory, file system storage, database connection pool entries, and CPU. If an attacker can trigger the allocation of these limited resources, but the number or size of the resources is not controlled, then the attacker could cause a denial of service that consumes all available resources. This would prevent valid users from accessing the software, and it could potentially have an impact on the surrounding environment. For example, a memory exhaustion attack against an application could slow down the application as well as its host operating system.
There are at least three distinct scenarios which can commonly lead to resource exhaustion:
Lack of throttling for the number of allocated resources
Losing all references to a resource before reaching the shutdown stage
Not closing/returning a resource after processing
Resource exhaustion problems are often result due to an incorrect implementation of the following situations:
Error conditions and other exceptional circumstances.
Confusion over which part of the program is responsible for releasing the resource.

It is possible to craft a TIFF document where the IFD list is circular,
leading to an infinite loop while traversing the chain. The libtiff
directory reader has a failsafe that will break out of this loop after
reading 65535 directory entries, but it will continue processing,
consuming time and resources to process what is essentially a bogus TIFF
document.
This change fixes the above behavior by breaking out of processing when
a TIFF document has >= 65535 directories and terminating with an error. | 473851d211cf8805a161820337ca74cc9615d6ef | False | visit repo url | visit repo url | visit repo url | visit repo url | visit repo url | libtiff | visit repo url | visit repo url | TIFF_WriteOverview | TIFF_WriteOverview( TIFF * hTIFF , uint32 nXSize , uint32 nYSize , int nBitsPerPixel , int nPlanarConfig , int nSamples , int nBlockXSize , int nBlockYSize , int bTiled , int nCompressFlag , int nPhotometric , int nSampleFormat , unsigned short * panRed , unsigned short * panGreen , unsigned short * panBlue , int bUseSubIFDs , int nHorSubsampling , int nVerSubsampling) | ['hTIFF', 'nXSize', 'nYSize', 'nBitsPerPixel', 'nPlanarConfig', 'nSamples', 'nBlockXSize', 'nBlockYSize', 'bTiled', 'nCompressFlag', 'nPhotometric', 'nSampleFormat', 'panRed', 'panGreen', 'panBlue', 'bUseSubIFDs', 'nHorSubsampling', 'nVerSubsampling'] | uint32 TIFF_WriteOverview( TIFF *hTIFF, uint32 nXSize, uint32 nYSize,

The TIFFPrintDirectory function relies on the following assumptions,
supposed to be guaranteed by the specification:
(a) A Transfer Function field is only present if the TIFF file has
photometric type < 3.
(b) If SamplesPerPixel > Color Channels, then the ExtraSamples field
has count SamplesPerPixel - (Color Channels) and contains
information about supplementary channels.
While respect of (a) and (b) are essential for the well functioning of
TIFFPrintDirectory, no checks are realized neither by the callee nor
by TIFFPrintDirectory itself. Hence, following scenarios might happen
and trigger the NULL pointer dereference:
(1) TIFF File of photometric type 4 or more has illegal Transfer
Function field.
(2) TIFF File has photometric type 3 or less and defines a
SamplesPerPixel field such that SamplesPerPixel > Color Channels
without defining all extra samples in the ExtraSamples fields.
In this patch, we address both issues with respect of the following
principles:
(A) In the case of (1), the defined transfer table should be printed
safely even if it isn't 'legal'. This allows us to avoid expensive
checks in TIFFPrintDirectory. Also, it is quite possible that
an alternative photometric type would be developed (not part of the
standard) and would allow definition of Transfer Table. We want
libtiff to be able to handle this scenario out of the box.
(B) In the case of (2), the transfer table should be printed at its
right size, that is if TIFF file has photometric type Palette
then the transfer table should have one row and not three, even
if two extra samples are declared.
In order to fulfill (A) we simply add a new 'i < 3' end condition to
the broken TIFFPrintDirectory loop. This makes sure that in any case
where (b) would be respected but not (a), everything stays fine.
(B) is fulfilled by the loop condition
'i < td->td_samplesperpixel - td->td_extrasamples'. This is enough as
long as (b) is respected.
Naturally, we also make sure (b) is respected. This is done in the
TIFFReadDirectory function by making sure any non-color channel is
counted in ExtraSamples.

JBIGDecode doesn't check if the user provided buffer is large enough
to store the JBIG decoded image, which can potentially cause out-of-bounds
write in the buffer.
This issue was reported and analyzed by Thomas Dullien.
Also fixes a (harmless) potential use of uninitialized memory when
tif->tif_rawsize > tif->tif_rawcc
And in case libtiff is compiled with CHUNKY_STRIP_READ_SUPPORT, make sure
that whole strip data is provided to JBIGDecode() | 681748ec2f5ce88da5f9fa6831e1653e46af8a66 | False | visit repo url | visit repo url | visit repo url | visit repo url | visit repo url | libtiff | visit repo url | visit repo url | JBIGDecode | JBIGDecode( TIFF * tif , uint8 * buffer , tmsize_t size , uint16 s) | ['tif', 'buffer', 'size', 's'] | static int JBIGDecode(TIFF* tif, uint8* buffer, tmsize_t size, uint16 s)

to store the JBIG decoded image, which can potentially cause out-of-bounds
write in the buffer.
This issue was reported and analyzed by Thomas Dullien.
Also fixes a (harmless) potential use of uninitialized memory when
tif->tif_rawsize > tif->tif_rawcc
And in case libtiff is compiled with CHUNKY_STRIP_READ_SUPPORT, make sure
that whole strip data is provided to JBIGDecode() | 681748ec2f5ce88da5f9fa6831e1653e46af8a66 | False | visit repo url | visit repo url | visit repo url | visit repo url | visit repo url | libtiff | visit repo url | visit repo url | TIFFSeek | TIFFSeek( TIFF * tif , uint32 row , uint16 sample) | ['tif', 'row', 'sample'] | TIFFSeek(TIFF* tif, uint32 row, uint16 sample )

not validate or incorrectly validates that the input has the
properties that are required to process the data safely and
correctly. |
Input validation is a frequently-used technique
for checking potentially dangerous inputs in order to
ensure that the inputs are safe for processing within the
code, or when communicating with other components. When
software does not validate input properly, an attacker is
able to craft the input in a form that is not expected by
the rest of the application. This will lead to parts of the
system receiving unintended input, which may result in
altered control flow, arbitrary control of a resource, or
arbitrary code execution.
Input validation is not the only technique for
processing input, however. Other techniques attempt to
transform potentially-dangerous input into something safe, such
as filtering (CWE-790) - which attempts to remove dangerous
inputs - or encoding/escaping (CWE-116), which attempts to
ensure that the input is not misinterpreted when it is included
in output to another component. Other techniques exist as well
(see CWE-138 for more examples.)
Input validation can be applied to:
raw data - strings, numbers, parameters, file contents, etc.
metadata - information about the raw data, such as headers or size
Data can be simple or structured. Structured data
can be composed of many nested layers, composed of
combinations of metadata and raw data, with other simple or
structured data.
Many properties of raw data or metadata may need
to be validated upon entry into the code, such
as:
specified quantities such as size, length, frequency, price, rate, number of operations, time, etc.
implied or derived quantities, such as the actual size of a file instead of a specified size
indexes, offsets, or positions into more complex data structures
symbolic keys or other elements into hash tables, associative arrays, etc.
well-formedness, i.e. syntactic correctness - compliance with expected syntax
lexical token correctness - compliance with rules for what is treated as a token
specified or derived type - the actual type of the input (or what the input appears to be)
consistency - between individual data elements, between raw data and metadata, between references, etc.
conformance to domain-specific rules, e.g. business logic
equivalence - ensuring that equivalent inputs are treated the same
authenticity, ownership, or other attestations about the input, e.g. a cryptographic signature to prove the source of the data
Implied or derived properties of data must often
be calculated or inferred by the code itself. Errors in
deriving properties may be considered a contributing factor
to improper input validation.
Note that "input validation" has very different
meanings to different people, or within different
classification schemes. Caution must be used when
referencing this CWE entry or mapping to it. For example,
some weaknesses might involve inadvertently giving control
to an attacker over an input when they should not be able
to provide an input at all, but sometimes this is referred
to as input validation.
Finally, it is important to emphasize that the
distinctions between input validation and output escaping
are often blurred, and developers must be careful to
understand the difference, including how input validation
is not always sufficient to prevent vulnerabilities,
especially when less stringent data types must be
supported, such as free-form text. Consider a SQL injection
scenario in which a person's last name is inserted into a
query. The name "O'Reilly" would likely pass the validation
step since it is a common last name in the English
language. However, this valid name cannot be directly
inserted into the database because it contains the "'"
apostrophe character, which would need to be escaped or
otherwise transformed. In this case, removing the
apostrophe might reduce the risk of SQL injection, but it
would produce incorrect behavior because the wrong name
would be recorded.

The software may modify an index or perform pointer arithmetic that references a memory location that is outside of the boundaries of the buffer. A subsequent write operation then produces undefined or unexpected results.

When a connection is not reset properly at the TCP level (e.g. sudden
power loss or process crash) the TCP connection becomes half-open and
read() always returns -1 with errno = EAGAIN while select() always
returns 0. This leads to an infinite loop and can be fixed by closing
the connection after a certain number of retries (based on a timeout)
has been exceeded. | 57433015f856cc12753378254ce4f1c78f5d9c7b | False | LibVNC/libvncserver | LibVNCServer/LibVNCClient are cross-platform C libraries that allow you to easily implement VNC server or client functionality in your program. | 2014-03-31 00:55:53 | 2022-08-23 09:29:14 | LibVNC | 857.0 | 408.0 | ReadFromRFBServer | ReadFromRFBServer( rfbClient * client , char * out , unsigned int n) | ['client', 'out', 'n'] | ReadFromRFBServer(rfbClient* client, char *out, unsigned int n)

In ngx_gmtime(), instead of casting to ngx_uint_t we now work with
time_t directly. This allows using dates after 2038 on 32-bit platforms
which use 64-bit time_t, notably NetBSD and OpenBSD.
As the code is not able to work with negative time_t values, argument
is now set to 0 for negative values. As a positive side effect, this
results in Epoch being used for such values instead of a date in distant
future. | 0206ebe76f748bb39d9de4dd4b3fce777fdfdccf | False | nginx/nginx | An official read-only mirror of http://hg.nginx.org/nginx/ which is updated hourly.

not validate or incorrectly validates that the input has the
properties that are required to process the data safely and
correctly. |
Input validation is a frequently-used technique
for checking potentially dangerous inputs in order to
ensure that the inputs are safe for processing within the
code, or when communicating with other components. When
software does not validate input properly, an attacker is
able to craft the input in a form that is not expected by
the rest of the application. This will lead to parts of the
system receiving unintended input, which may result in
altered control flow, arbitrary control of a resource, or
arbitrary code execution.
Input validation is not the only technique for
processing input, however. Other techniques attempt to
transform potentially-dangerous input into something safe, such
as filtering (CWE-790) - which attempts to remove dangerous
inputs - or encoding/escaping (CWE-116), which attempts to
ensure that the input is not misinterpreted when it is included
in output to another component. Other techniques exist as well
(see CWE-138 for more examples.)
Input validation can be applied to:
raw data - strings, numbers, parameters, file contents, etc.
metadata - information about the raw data, such as headers or size
Data can be simple or structured. Structured data
can be composed of many nested layers, composed of
combinations of metadata and raw data, with other simple or
structured data.
Many properties of raw data or metadata may need
to be validated upon entry into the code, such
as:
specified quantities such as size, length, frequency, price, rate, number of operations, time, etc.
implied or derived quantities, such as the actual size of a file instead of a specified size
indexes, offsets, or positions into more complex data structures
symbolic keys or other elements into hash tables, associative arrays, etc.
well-formedness, i.e. syntactic correctness - compliance with expected syntax
lexical token correctness - compliance with rules for what is treated as a token
specified or derived type - the actual type of the input (or what the input appears to be)
consistency - between individual data elements, between raw data and metadata, between references, etc.
conformance to domain-specific rules, e.g. business logic
equivalence - ensuring that equivalent inputs are treated the same
authenticity, ownership, or other attestations about the input, e.g. a cryptographic signature to prove the source of the data
Implied or derived properties of data must often
be calculated or inferred by the code itself. Errors in
deriving properties may be considered a contributing factor
to improper input validation.
Note that "input validation" has very different
meanings to different people, or within different
classification schemes. Caution must be used when
referencing this CWE entry or mapping to it. For example,
some weaknesses might involve inadvertently giving control
to an attacker over an input when they should not be able
to provide an input at all, but sometimes this is referred
to as input validation.
Finally, it is important to emphasize that the
distinctions between input validation and output escaping
are often blurred, and developers must be careful to
understand the difference, including how input validation
is not always sufficient to prevent vulnerabilities,
especially when less stringent data types must be
supported, such as free-form text. Consider a SQL injection
scenario in which a person's last name is inserted into a
query. The name "O'Reilly" would likely pass the validation
step since it is a common last name in the English
language. However, this valid name cannot be directly
inserted into the database because it contains the "'"
apostrophe character, which would need to be escaped or
otherwise transformed. In this case, removing the
apostrophe might reduce the risk of SQL injection, but it
would produce incorrect behavior because the wrong name
would be recorded.

not validate or incorrectly validates that the input has the
properties that are required to process the data safely and
correctly. |
Input validation is a frequently-used technique
for checking potentially dangerous inputs in order to
ensure that the inputs are safe for processing within the
code, or when communicating with other components. When
software does not validate input properly, an attacker is
able to craft the input in a form that is not expected by
the rest of the application. This will lead to parts of the
system receiving unintended input, which may result in
altered control flow, arbitrary control of a resource, or
arbitrary code execution.
Input validation is not the only technique for
processing input, however. Other techniques attempt to
transform potentially-dangerous input into something safe, such
as filtering (CWE-790) - which attempts to remove dangerous
inputs - or encoding/escaping (CWE-116), which attempts to
ensure that the input is not misinterpreted when it is included
in output to another component. Other techniques exist as well
(see CWE-138 for more examples.)
Input validation can be applied to:
raw data - strings, numbers, parameters, file contents, etc.
metadata - information about the raw data, such as headers or size
Data can be simple or structured. Structured data
can be composed of many nested layers, composed of
combinations of metadata and raw data, with other simple or
structured data.
Many properties of raw data or metadata may need
to be validated upon entry into the code, such
as:
specified quantities such as size, length, frequency, price, rate, number of operations, time, etc.
implied or derived quantities, such as the actual size of a file instead of a specified size
indexes, offsets, or positions into more complex data structures
symbolic keys or other elements into hash tables, associative arrays, etc.
well-formedness, i.e. syntactic correctness - compliance with expected syntax
lexical token correctness - compliance with rules for what is treated as a token
specified or derived type - the actual type of the input (or what the input appears to be)
consistency - between individual data elements, between raw data and metadata, between references, etc.
conformance to domain-specific rules, e.g. business logic
equivalence - ensuring that equivalent inputs are treated the same
authenticity, ownership, or other attestations about the input, e.g. a cryptographic signature to prove the source of the data
Implied or derived properties of data must often
be calculated or inferred by the code itself. Errors in
deriving properties may be considered a contributing factor
to improper input validation.
Note that "input validation" has very different
meanings to different people, or within different
classification schemes. Caution must be used when
referencing this CWE entry or mapping to it. For example,
some weaknesses might involve inadvertently giving control
to an attacker over an input when they should not be able
to provide an input at all, but sometimes this is referred
to as input validation.
Finally, it is important to emphasize that the
distinctions between input validation and output escaping
are often blurred, and developers must be careful to
understand the difference, including how input validation
is not always sufficient to prevent vulnerabilities,
especially when less stringent data types must be
supported, such as free-form text. Consider a SQL injection
scenario in which a person's last name is inserted into a
query. The name "O'Reilly" would likely pass the validation
step since it is a common last name in the English
language. However, this valid name cannot be directly
inserted into the database because it contains the "'"
apostrophe character, which would need to be escaped or
otherwise transformed. In this case, removing the
apostrophe might reduce the risk of SQL injection, but it
would produce incorrect behavior because the wrong name
would be recorded.

An attacker could pre-create /tmp/.bubblewrap-$UID and make it a
non-directory, non-symlink (in which case mounting our tmpfs would fail,
causing denial of service), or make it a symlink under their control
(potentially allowing bad things if the protected_symlinks sysctl is
not enabled).
Instead, temporarily mount the tmpfs on a directory that we are sure
exists and is not attacker-controlled. /tmp (the directory itself, not
a subdirectory) will do.

not validate or incorrectly validates that the input has the
properties that are required to process the data safely and
correctly. |
Input validation is a frequently-used technique
for checking potentially dangerous inputs in order to
ensure that the inputs are safe for processing within the
code, or when communicating with other components. When
software does not validate input properly, an attacker is
able to craft the input in a form that is not expected by
the rest of the application. This will lead to parts of the
system receiving unintended input, which may result in
altered control flow, arbitrary control of a resource, or
arbitrary code execution.
Input validation is not the only technique for
processing input, however. Other techniques attempt to
transform potentially-dangerous input into something safe, such
as filtering (CWE-790) - which attempts to remove dangerous
inputs - or encoding/escaping (CWE-116), which attempts to
ensure that the input is not misinterpreted when it is included
in output to another component. Other techniques exist as well
(see CWE-138 for more examples.)
Input validation can be applied to:
raw data - strings, numbers, parameters, file contents, etc.
metadata - information about the raw data, such as headers or size
Data can be simple or structured. Structured data
can be composed of many nested layers, composed of
combinations of metadata and raw data, with other simple or
structured data.
Many properties of raw data or metadata may need
to be validated upon entry into the code, such
as:
specified quantities such as size, length, frequency, price, rate, number of operations, time, etc.
implied or derived quantities, such as the actual size of a file instead of a specified size
indexes, offsets, or positions into more complex data structures
symbolic keys or other elements into hash tables, associative arrays, etc.
well-formedness, i.e. syntactic correctness - compliance with expected syntax
lexical token correctness - compliance with rules for what is treated as a token
specified or derived type - the actual type of the input (or what the input appears to be)
consistency - between individual data elements, between raw data and metadata, between references, etc.
conformance to domain-specific rules, e.g. business logic
equivalence - ensuring that equivalent inputs are treated the same
authenticity, ownership, or other attestations about the input, e.g. a cryptographic signature to prove the source of the data
Implied or derived properties of data must often
be calculated or inferred by the code itself. Errors in
deriving properties may be considered a contributing factor
to improper input validation.
Note that "input validation" has very different
meanings to different people, or within different
classification schemes. Caution must be used when
referencing this CWE entry or mapping to it. For example,
some weaknesses might involve inadvertently giving control
to an attacker over an input when they should not be able
to provide an input at all, but sometimes this is referred
to as input validation.
Finally, it is important to emphasize that the
distinctions between input validation and output escaping
are often blurred, and developers must be careful to
understand the difference, including how input validation
is not always sufficient to prevent vulnerabilities,
especially when less stringent data types must be
supported, such as free-form text. Consider a SQL injection
scenario in which a person's last name is inserted into a
query. The name "O'Reilly" would likely pass the validation
step since it is a common last name in the English
language. However, this valid name cannot be directly
inserted into the database because it contains the "'"
apostrophe character, which would need to be escaped or
otherwise transformed. In this case, removing the
apostrophe might reduce the risk of SQL injection, but it

not validate or incorrectly validates that the input has the
properties that are required to process the data safely and
correctly. |
Input validation is a frequently-used technique
for checking potentially dangerous inputs in order to
ensure that the inputs are safe for processing within the
code, or when communicating with other components. When
software does not validate input properly, an attacker is
able to craft the input in a form that is not expected by
the rest of the application. This will lead to parts of the
system receiving unintended input, which may result in
altered control flow, arbitrary control of a resource, or
arbitrary code execution.
Input validation is not the only technique for
processing input, however. Other techniques attempt to
transform potentially-dangerous input into something safe, such
as filtering (CWE-790) - which attempts to remove dangerous
inputs - or encoding/escaping (CWE-116), which attempts to
ensure that the input is not misinterpreted when it is included
in output to another component. Other techniques exist as well
(see CWE-138 for more examples.)
Input validation can be applied to:
raw data - strings, numbers, parameters, file contents, etc.
metadata - information about the raw data, such as headers or size
Data can be simple or structured. Structured data
can be composed of many nested layers, composed of
combinations of metadata and raw data, with other simple or
structured data.
Many properties of raw data or metadata may need
to be validated upon entry into the code, such
as:
specified quantities such as size, length, frequency, price, rate, number of operations, time, etc.
implied or derived quantities, such as the actual size of a file instead of a specified size
indexes, offsets, or positions into more complex data structures
symbolic keys or other elements into hash tables, associative arrays, etc.
well-formedness, i.e. syntactic correctness - compliance with expected syntax
lexical token correctness - compliance with rules for what is treated as a token
specified or derived type - the actual type of the input (or what the input appears to be)
consistency - between individual data elements, between raw data and metadata, between references, etc.
conformance to domain-specific rules, e.g. business logic
equivalence - ensuring that equivalent inputs are treated the same
authenticity, ownership, or other attestations about the input, e.g. a cryptographic signature to prove the source of the data
Implied or derived properties of data must often
be calculated or inferred by the code itself. Errors in
deriving properties may be considered a contributing factor
to improper input validation.
Note that "input validation" has very different
meanings to different people, or within different
classification schemes. Caution must be used when
referencing this CWE entry or mapping to it. For example,
some weaknesses might involve inadvertently giving control
to an attacker over an input when they should not be able
to provide an input at all, but sometimes this is referred
to as input validation.
Finally, it is important to emphasize that the
distinctions between input validation and output escaping
are often blurred, and developers must be careful to
understand the difference, including how input validation
is not always sufficient to prevent vulnerabilities,
especially when less stringent data types must be
supported, such as free-form text. Consider a SQL injection
scenario in which a person's last name is inserted into a
query. The name "O'Reilly" would likely pass the validation
step since it is a common last name in the English
language. However, this valid name cannot be directly
inserted into the database because it contains the "'"
apostrophe character, which would need to be escaped or
otherwise transformed. In this case, removing the
apostrophe might reduce the risk of SQL injection, but it
would produce incorrect behavior because the wrong name
would be recorded.

not validate or incorrectly validates that the input has the
properties that are required to process the data safely and
correctly. |
Input validation is a frequently-used technique
for checking potentially dangerous inputs in order to
ensure that the inputs are safe for processing within the
code, or when communicating with other components. When
software does not validate input properly, an attacker is
able to craft the input in a form that is not expected by
the rest of the application. This will lead to parts of the
system receiving unintended input, which may result in
altered control flow, arbitrary control of a resource, or
arbitrary code execution.
Input validation is not the only technique for
processing input, however. Other techniques attempt to
transform potentially-dangerous input into something safe, such
as filtering (CWE-790) - which attempts to remove dangerous
inputs - or encoding/escaping (CWE-116), which attempts to
ensure that the input is not misinterpreted when it is included
in output to another component. Other techniques exist as well
(see CWE-138 for more examples.)
Input validation can be applied to:
raw data - strings, numbers, parameters, file contents, etc.
metadata - information about the raw data, such as headers or size
Data can be simple or structured. Structured data
can be composed of many nested layers, composed of
combinations of metadata and raw data, with other simple or
structured data.
Many properties of raw data or metadata may need
to be validated upon entry into the code, such
as:
specified quantities such as size, length, frequency, price, rate, number of operations, time, etc.
implied or derived quantities, such as the actual size of a file instead of a specified size
indexes, offsets, or positions into more complex data structures
symbolic keys or other elements into hash tables, associative arrays, etc.
well-formedness, i.e. syntactic correctness - compliance with expected syntax
lexical token correctness - compliance with rules for what is treated as a token
specified or derived type - the actual type of the input (or what the input appears to be)
consistency - between individual data elements, between raw data and metadata, between references, etc.
conformance to domain-specific rules, e.g. business logic
equivalence - ensuring that equivalent inputs are treated the same
authenticity, ownership, or other attestations about the input, e.g. a cryptographic signature to prove the source of the data
Implied or derived properties of data must often
be calculated or inferred by the code itself. Errors in
deriving properties may be considered a contributing factor
to improper input validation.
Note that "input validation" has very different
meanings to different people, or within different
classification schemes. Caution must be used when
referencing this CWE entry or mapping to it. For example,
some weaknesses might involve inadvertently giving control
to an attacker over an input when they should not be able
to provide an input at all, but sometimes this is referred
to as input validation.
Finally, it is important to emphasize that the
distinctions between input validation and output escaping
are often blurred, and developers must be careful to
understand the difference, including how input validation
is not always sufficient to prevent vulnerabilities,
especially when less stringent data types must be
supported, such as free-form text. Consider a SQL injection
scenario in which a person's last name is inserted into a
query. The name "O'Reilly" would likely pass the validation
step since it is a common last name in the English
language. However, this valid name cannot be directly
inserted into the database because it contains the "'"
apostrophe character, which would need to be escaped or
otherwise transformed. In this case, removing the
apostrophe might reduce the risk of SQL injection, but it
would produce incorrect behavior because the wrong name
would be recorded.

This can introduce other weaknesses when the calculation is used for resource management or execution control. | An integer overflow or wraparound occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may wrap to become a very small or negative number. While this may be intended behavior in circumstances that rely on wrapping, it can have security consequences if the wrap is unexpected. This is especially the case if the integer overflow can be triggered using user-supplied inputs. This becomes security-critical when the result is used to control looping, make a security decision, or determine the offset or size in behaviors such as memory allocation, copying, concatenation, etc.

This could allow attackers to execute unexpected, dangerous commands directly on the operating system. This weakness can lead to a vulnerability in environments in which the attacker does not have direct access to the operating system, such as in web applications. Alternately, if the weakness occurs in a privileged program, it could allow the attacker to specify commands that normally would not be accessible, or to call alternate commands with privileges that the attacker does not have. The problem is exacerbated if the compromised process does not follow the principle of least privilege, because the attacker-controlled commands may run with special system privileges that increases the amount of damage.
There are at least two subtypes of OS command injection:
The application intends to execute a single, fixed program that is under its own control. It intends to use externally-supplied inputs as arguments to that program. For example, the program might use system("nslookup [HOSTNAME]") to run nslookup and allow the user to supply a HOSTNAME, which is used as an argument. Attackers cannot prevent nslookup from executing. However, if the program does not remove command separators from the HOSTNAME argument, attackers could place the separators into the arguments, which allows them to execute their own program after nslookup has finished executing.
The application accepts an input that it uses to fully select which program to run, as well as which commands to use. The application simply redirects this entire command to the operating system. For example, the program might use "exec([COMMAND])" to execute the [COMMAND] that was supplied by the user. If the COMMAND is under attacker control, then the attacker can execute arbitrary commands or programs. If the command is being executed using functions like exec() and CreateProcess(), the attacker might not be able to combine multiple commands together in the same line.
From a weakness standpoint, these variants represent distinct programmer errors. In the first variant, the programmer clearly intends that input from untrusted parties will be part of the arguments in the command to be executed. In the second variant, the programmer does not intend for the command to be accessible to any untrusted party, but the programmer probably has not accounted for alternate ways in which malicious attackers can provide input.

This could allow attackers to execute unexpected, dangerous commands directly on the operating system. This weakness can lead to a vulnerability in environments in which the attacker does not have direct access to the operating system, such as in web applications. Alternately, if the weakness occurs in a privileged program, it could allow the attacker to specify commands that normally would not be accessible, or to call alternate commands with privileges that the attacker does not have. The problem is exacerbated if the compromised process does not follow the principle of least privilege, because the attacker-controlled commands may run with special system privileges that increases the amount of damage.
There are at least two subtypes of OS command injection:
The application intends to execute a single, fixed program that is under its own control. It intends to use externally-supplied inputs as arguments to that program. For example, the program might use system("nslookup [HOSTNAME]") to run nslookup and allow the user to supply a HOSTNAME, which is used as an argument. Attackers cannot prevent nslookup from executing. However, if the program does not remove command separators from the HOSTNAME argument, attackers could place the separators into the arguments, which allows them to execute their own program after nslookup has finished executing.
The application accepts an input that it uses to fully select which program to run, as well as which commands to use. The application simply redirects this entire command to the operating system. For example, the program might use "exec([COMMAND])" to execute the [COMMAND] that was supplied by the user. If the COMMAND is under attacker control, then the attacker can execute arbitrary commands or programs. If the command is being executed using functions like exec() and CreateProcess(), the attacker might not be able to combine multiple commands together in the same line.
From a weakness standpoint, these variants represent distinct programmer errors. In the first variant, the programmer clearly intends that input from untrusted parties will be part of the arguments in the command to be executed. In the second variant, the programmer does not intend for the command to be accessible to any untrusted party, but the programmer probably has not accounted for alternate ways in which malicious attackers can provide input.

In the first variant, the programmer clearly intends that input from untrusted parties will be part of the arguments in the command to be executed. In the second variant, the programmer does not intend for the command to be accessible to any untrusted party, but the programmer probably has not accounted for alternate ways in which malicious attackers can provide input.

This could allow attackers to execute unexpected, dangerous commands directly on the operating system. This weakness can lead to a vulnerability in environments in which the attacker does not have direct access to the operating system, such as in web applications. Alternately, if the weakness occurs in a privileged program, it could allow the attacker to specify commands that normally would not be accessible, or to call alternate commands with privileges that the attacker does not have. The problem is exacerbated if the compromised process does not follow the principle of least privilege, because the attacker-controlled commands may run with special system privileges that increases the amount of damage.
There are at least two subtypes of OS command injection:
The application intends to execute a single, fixed program that is under its own control. It intends to use externally-supplied inputs as arguments to that program. For example, the program might use system("nslookup [HOSTNAME]") to run nslookup and allow the user to supply a HOSTNAME, which is used as an argument. Attackers cannot prevent nslookup from executing. However, if the program does not remove command separators from the HOSTNAME argument, attackers could place the separators into the arguments, which allows them to execute their own program after nslookup has finished executing.
The application accepts an input that it uses to fully select which program to run, as well as which commands to use. The application simply redirects this entire command to the operating system. For example, the program might use "exec([COMMAND])" to execute the [COMMAND] that was supplied by the user. If the COMMAND is under attacker control, then the attacker can execute arbitrary commands or programs. If the command is being executed using functions like exec() and CreateProcess(), the attacker might not be able to combine multiple commands together in the same line.
From a weakness standpoint, these variants represent distinct programmer errors. In the first variant, the programmer clearly intends that input from untrusted parties will be part of the arguments in the command to be executed.
