Moxa IKS, EDS (Update A)
Several buffer overflow vulnerabilities have been identified, which may allow remote code execution.CVE-2019-6557 has been assigned to this vulnerability. A CVSS v3 base score of 9.8 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H). A cross-site request forgery has been identified, which may allow for the execution of unauthorized actions on the device.CVE-2019-6561 has been assigned to this vulnerability. A CVSS v3 base score of 9.6 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H). The device fails to properly validate user input, giving unauthenticated and authenticated attackers the ability to perform XSS attacks, which may be used to send a malicious script.CVE-2019-6565 has been assigned to this vulnerability. A CVSS v3 base score of 9.6 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H). The device does not properly check authority on server side, which results in a read-only user being able to perform arbitrary configuration changes.CVE-2019-6520 has been assigned to this vulnerability. A CVSS v3 base score of 9.1 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H). The devices do not implement sufficient measures to prevent multiple failed authentication attempts, which may allow an attacker to discover passwords via brute force attack.CVE-2019-6524 has been assigned to this vulnerability. A CVSS v3 base score of 9.8 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H). The devices use plaintext transmission of sensitive data, which may allow an attacker to capture sensitive data such as an administrative password.CVE-2019-6526 has been assigned to this vulnerability. A CVSS v3 base score of 9.8 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H). Failure to properly check array bounds may allow an attacker to read device memory on arbitrary addresses, which may allow an attacker to retrieve sensitive data or cause device reboot.CVE-2019-6522 has been assigned to this vulnerability. A CVSS v3 base score of 9.1 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H). The devices store plaintext passwords, which may allow sensitive information to be read by someone with access to the device.CVE-2019-6518 has been assigned to this vulnerability. A CVSS v3 base score of 7.5 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N). The software generates a predictable cookie calculated with an MD5 hash, allowing an attacker to capture the administrator's password, which could lead to a full compromise of the device.CVE-2019-6563 has been assigned to this vulnerability. A CVSS v3 base score of 9.8 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H). The devices allow remote authenticated users to cause a denial of service via a specially crafted packet, which may cause the switch to crash.CVE-2019-6559 has been assigned to this vulnerability. A CVSS v3 base score of 7.5 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H).
