The vulnerability was found in Moodle, occurs due to improper input validation when parsing PostScript code. An omitted execution parameter results in a remote code execution risk for sites running GhostScript versions older than 9.50. Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - The vulnerability was found in Moodle, occurs due to improper input validation when parsing PostScript     code. An omitted execution parameter results in a remote code execution risk for sites running GhostScript     versions older than 9.50. Successful exploitation of this vulnerability may result in complete compromise     of vulnerable system. (CVE-2022-35649)

Note that Nessus relies on the presence of the package as reported by the vendor.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - The vulnerability was found in Moodle, occurs due to improper input validation when parsing PostScript
    code. An omitted execution parameter results in a remote code execution risk for sites running GhostScript
    versions older than 9.50. Successful exploitation of this vulnerability may result in complete compromise
    of vulnerable system. (CVE-2022-35649)

The version of Moodle installed on the remote host is 3.9.x prior to 3.9.15, 3.11.x prior to 3.11.8 or 4.0.x prior to 4.0.2. It is, therefore, affected by multiple vulnerabilities:

 - A code injection through an omitted execution parameter elading to Remote Code Execution (RCE) for sites running GhostScript versions older than 9.50. (CVE-2022-35649)

 - An arbitrary file read due to an insufficient path checks in a lesson question import available to teachers, managers and admins by default. (CVE-2022-35650)

 - A stored Cross-Site Scripting (XSS) and blind Server-Side Request Forgery (SSRF) vulnerabilities due to an insufficient sanitizing of SCORM track details. (CVE-2022-35651)

 - An open redirect vulnerability due to the lack of sanitization in the mobile auto-login URL. (CVE-2022-35652)

 - A Cross-Site Scripting (XSS) vulnerability in the LTI module only affecting unauthentication users. (CVE-2022-35653)

Note that the scanner has not attempted to exploit this issue but has instead relied only on application's self-reported version number.
