Recursive rendering of Mustache template helpers containing user input could, in some cases, result in an XSS risk or a page failing to load.

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

  - Recursive rendering of Mustache template helpers containing user input could, in some cases, result in an     XSS risk or a page failing to load. (CVE-2022-40313)

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:

  - Recursive rendering of Mustache template helpers containing user input could, in some cases, result in an
    XSS risk or a page failing to load. (CVE-2022-40313)

The version of Moodle installed on the remote host is 3.9.x prior to 3.9.17, 3.11.x prior to 3.11.10 or 4.0.x prior to 4.0.4. It is, therefore, affected by multiple vulnerabilities:

 - A stored Cross-Site Scripting (XSS) and page Denial of Service (DoS) vulnerabilities due to recursive rendering in Mustache template helpers. (CVE-2022-40313)

 - A Remote Code Execution (RCE) vulnerability when restoring backup files originating from Moodle 1.9. (CVE-2022-40314)

 - A limited SQL injection vulnerability in the "browse list of users" site administration page. (CVE-2022-40315)

 - An information disclosure in the H5P activity attempts report not filtering by groups, leading to data exposure to non-editing teachers about attempts and users in groups they should not have access to. (CVE-2022-40316)

 - An improper access control in some quiz web services allowing students to bypass sequential navigation during a quiz attempt. (CVE-2022-40208)

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