Yokogawa CENTUM and Exaopc
If the password for the OS account created when installing the product has not been changed from the default password and the hard-coded credentials (default password) for the account are used, an attacker could access files and shared memory in the system. The product is not affected by this vulnerability if the default password has been properly changed after installation.CVE-2022-21194 has been assigned to this vulnerability. A CVSS v3 base score of 7.1 has been calculated; the CVSS vector string is (AV:A/AC:H/PR:N/UI:N/S:U/C:L/I:H/A:H). If the hard-coded credentials for CAMS server application are used to send a malformed packet to CAMS server, all functions of CAMS server can be abused, including suppressing alarms.CVE-2022-23402 has been assigned to this vulnerability. A CVSS v3 base score of 7.8 has been calculated; the CVSS vector string is (AV:A/AC:H/PR:N/UI:R/S:C/C:L/I:H/A:H). A malformed packet sent to a CAMS for HIS server may allow an attacker to achieve relative path traversal and then read and write files or execute commands.CVE-2022-21808 and CVE-2022-22729 have been assigned to these vulnerabilities. A CVSS v3 base score of 7.1 has been calculated; the CVSS vector string is (AV:A/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H). A malformed packet sent to a CAMS for HIS server may exploit an output neutralization vulnerability, allowing an attacker to crash the server or manipulate log files.CVE-2022-22151, CVE-2022-21177. and CVE-2022-22145 have been assigned to these vulnerabilities. A CVSS v3 base score of 5.9 has been calculated; the CVSS vector string is (AV:A/AC:H/PR:N/UI:R/S:U/C:L/I:L/A:H). A local attacker may be able to utilize a named pipe with inappropriate access privileges to execute arbitrary programs.CVE-2022-22148 has been assigned to this vulnerability. A CVSS v3 base score of 8.6 has been calculated; the CVSS vector string is (AV:L/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H). A local attacker may be able to utilize a named pipe with inappropriate access privileges to delete arbitrary files.CVE-2022-22141 has been assigned to this vulnerability. A CVSS v3 base score of 6.6 has been calculated; the CVSS vector string is (AV:L/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:H). CENTUM and Exaopc have a DLL injection vulnerability and a DLL planting vulnerability using the DLL search order vulnerability. See this link for further details on this exploit type.CVE-2022-23401 has been assigned to this vulnerability. A CVSS v3 base score of 8.3 has been calculated; the CVSS vector string is (AV:A/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:H).
