Online Event Judging System CVE-2025-12252

No vendor-released patch has been identified at time of analysis. Immediate remediation requires upgrading to a patched version if available from carmelo/code-projects, or implementing input validation on the content parameter with parameterized queries (prepared statements) in /ajax/action.php to neutralize SQL injection. If patched versions are unavailable, apply compensating controls: (1) enforce strict input validation using allowlist patterns for the content parameter (trade-off: may restrict legitimate use cases requiring special characters), (2) implement database-level access controls restricting the application's database user to SELECT, UPDATE, DELETE only on necessary tables with no CREATE/DROP permissions (trade-off: requires database architecture review), (3) enable Web Application Firewall (WAF) rules to detect and block common SQL injection payloads (trade-off: potential for false positives), and (4) restrict access to /ajax/action.php to authenticated users via network segmentation or authentication middleware (already required by CVSS, but enforce rigorously).
