Courier Management System CVE-2025-11553

Upgrade to a patched version of Courier Management System if available from the vendor at code-projects.org; however, no specific patched version is publicly documented in the provided references. Immediate compensating controls include: (1) Implement parameterized queries (prepared statements) in the /add-courier.php file to separate SQL logic from user input - this eliminates SQL injection risk and requires code changes by the development team. (2) Restrict access to the /add-courier.php endpoint via network access control lists or IP whitelisting to trusted administrative networks, reducing the attack surface to insider threats only. (3) Enable comprehensive SQL query logging and audit all queries executed with the Shippername parameter to detect anomalous database activity. (4) Apply input validation and length limits to the Shippername field at the application layer (whitelist alphanumeric characters, reject special SQL metacharacters). (5) Run the application with a database user account that has minimal permissions (INSERT only on the courier table, no SELECT on sensitive tables) to limit the blast radius if injection succeeds. Contact the vendor at code-projects.org or the original reporter (cna@vuldb.com) for patch availability and timeline.
