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).

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

  - 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-2025-26525)

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

According to its self-reported version, the Moodle install hosted on the remote host is prior to 4.1.16 or 4.3.x prior to 4.3.10 or 4.4.x prior to 4.4.6 or 4.5.x prior to 4.5.2. It is, therefore, affected by multiple vulnerabilities.

- An SQL injection risk was identified in the module list filter within course search.

- Additional checks were required to ensure trusttext is applied (when enabled) to glossary entries being restored.

- Insufficient capability checks made it possible to disable badges a user does not have permission to access.

- The upstream RequireJS library was upgraded, which included a security fix.

- The question bank filter required additional sanitizing to prevent a reflected XSS risk.

- Description information displayed in the site administration live log required additional sanitizing to prevent a stored XSS risk.

- The drag-and-drop onto image (ddimageortext) question type required additional sanitizing to prevent a stored XSS risk.

- Tags not expected to be visible to a user could still be discovered by them via the tag search page or in the tags block.

- Separate Groups mode restrictions were not factored into permission checks before allowing viewing or deletion of responses in Feedback activities.

- 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).

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:

  - 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-2025-26525)
