CVE-2023-35132
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA limited SQL injection risk was identified on the Mnet SSO access control page. This flaw affects Moodle versions 4.2, 4.1 to 4.1.3, 4.0 to 4.0.8, 3.11 to 3.11.14, 3.9 to 3.9.21 and earlier unsupported versions.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysisUser input is woven into a database query, letting an attacker rewrite the query's logic. From there they can read, alter, or destroy data — frequently the entire database. The reliable fix is parameterised queries (prepared statements), so input is always treated as data and never as SQL.

Upgrade to Moodle 3.9.22, 3.11.15, 4.0.9, or 4.1.4 (or later) depending on your current branch
- 1. Back up your Moodle database and code directory before proceeding.
- 2. Identify your current Moodle version by checking the version.php file in the root directory.
- 3. Download the appropriate fixed version for your branch: 3.9.22, 3.11.15, 4.0.9, or 4.1.4 from the official Moodle downloads page (download.moodle.org).
- 4. Replace your Moodle code directory with the new version, preserving your config.php and any custom plugins.
- 5. Run the Moodle upgrade process by accessing the site URL - the system will automatically detect and apply database upgrades.
- 6. Clear all caches via Site Administration > Development > Purge caches or by running php admin/cli/purge_caches.php.
- 7. Verify the Mnet SSO functionality works correctly after upgrade.
