According to its self-reported version, the Moodle install hosted on the remote host is 4.1.x prior to 4.1.12, 4.2.x prior to 4.2.9, 4.3.x prior to 4.3.6, or 4.4.x prior to 4.4.2. It is, therefore, affected by multiple vulnerabilities.

- A LFI vulnerability when restoring malformed block backups.

- A reflected XSS via H5P error message.

- An IDOR in Feedback non-respondents report allows messaging arbitrary site users.

- An XSS risk when restoring malicious course backup file.

- A site administration SQL injection via XMLDB editor.

- Can create global glossary without being admin.

- A CSRF risk in Feedback non-respondents report.

- Authorization headers preserved between "emulated redirects".

- An IDOR in badges allows deletion of arbitrary badges.

- User information visibility control issues in gradebook reports.

- Cache poisoning via injection into storage.

- Admin presets export tool includes some secrets that should not be exported.

- An arbitrary file read risk through pdfTeX.

Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.

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

  - A flaw was found in pdfTeX. Insufficient sanitizing in the TeX notation filter resulted in an arbitrary
    file read risk on sites where pdfTeX is available, such as those with TeX Live installed. (CVE-2024-43426)

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

  - A flaw was found in pdfTeX. Insufficient sanitizing in the TeX notation filter resulted in an arbitrary     file read risk on sites where pdfTeX is available, such as those with TeX Live installed. (CVE-2024-43426)

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