Database extraction via unvalidated sort parameter SQL injection
Published Aug 26, 2026 · Updated Aug 26, 2026
SQL injection in LibreNMS 1.65 allows remote authenticated users to extract all database information through ajax_table.php. The endpoint incorporates attacker-controlled sort values into SQL ordering clauses used by the listed includes/html/table handlers without parameterization or an allowlist. Normal application privileges and network access to the authenticated API endpoint are sufficient; the reported impact is read access to the complete LibreNMS database.
