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.

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

  - A stored XSS and blind SSRF vulnerability was found in Moodle, occurs due to insufficient sanitization of
    user-supplied data in the SCORM track details. A remote attacker can trick the victim to follow a
    specially crafted link and execute arbitrary HTML and script code in user's browser in context of
    vulnerable website to steal potentially sensitive information, change appearance of the web page, can
    perform phishing and drive-by-download attacks. (CVE-2022-35651)

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

  - A stored XSS and blind SSRF vulnerability was found in Moodle, occurs due to insufficient sanitization of     user-supplied data in the SCORM track details. A remote attacker can trick the victim to follow a     specially crafted link and execute arbitrary HTML and script code in user's browser in context of     vulnerable website to steal potentially sensitive information, change appearance of the web page, can     perform phishing and drive-by-download attacks. (CVE-2022-35651)

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