According to its self-reported version, the Moodle install hosted on the remote host is 4.1.x prior to 4.1.19, or 4.4.x prior to 4.4.9, or 4.5.x prior to 4.5.5, or 5.x prior to 5.0.1. It is, therefore, affected by multiple vulnerabilities :

- A stricter capability check was required to restrict which users can fetch other users' recently accessed courses information.

- Insufficient authorisation checks could result in users being able to view BigBlueButton recordings they did not have permission to access.

- The "move up" and "move down" actions in backpack management for badges did not include the necessary token to prevent a CSRF risk.

- Insufficient state and capability checks resulted in some details of hidden courses (such as course name, description and teachers) being available to users who did not have permission to access them.

- A DNS rebind risk in the way cURL requests were handled could result in an SSRF risk, due to the possibility of cURL blocked hosts / allowed ports site configurations being bypassed.

- The upstream ADOdb library contained an SQL injection risk in the pg_insert_id() method. It is important to note that the core Moodle LMS was NOT affected by this vulnerability, however as a precaution, this library has been upgraded to remove the risk entirely, in case any third party code/plugins uses the vulnerable code.

- Additional cache controls were required to prevent web browsers caching a user's password on the login page (note accessing this would require access to the web browser on the device where the user had logged in).

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

    Package        : libphp-adodb     Version        : 5.20.19-1+deb11u2     CVE ID         : CVE-2025-46337     Debian Bug     : 1104548

    SQL injection in the PostgreSQL driver has been fixed in the ADOdb     database access library for PHP.

    For Debian 11 bullseye, this problem has been fixed in version     5.20.19-1+deb11u2.

    We recommend that you upgrade your libphp-adodb packages.

    For the detailed security status of libphp-adodb please refer to     its security tracker page at:

The remote Fedora 42 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2025-118f6569ff advisory.

    5.22.9

Tenable has extracted the preceding description block directly from the Fedora security advisory.

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

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

  - ADOdb is a PHP database class library that provides abstractions for performing queries and managing     databases. Prior to version 5.22.9, improper escaping of a query parameter may allow an attacker to     execute arbitrary SQL statements when the code using ADOdb connects to a PostgreSQL database and calls     pg_insert_id() with user-supplied data. This issue has been patched in version 5.22.9. (CVE-2025-46337)

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

The remote Ubuntu 24.10 / 25.04 host has a package installed that is affected by a vulnerability as referenced in the USN-7530-1 advisory.

    It was discovered that ADOdb incorrectly handled SQL input. A remote attacker could use this issue to     execute arbitrary SQL commands.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
