DescriptionGitHub Advisory

Chamilo is a learning management system. Prior to version 1.11.30, there is an error-based SQL Injection via POST userFile with the /main/exercise/hotpotatoes.php script. This issue has been patched in version 1.11.30.

Executive ViewAI

Why It Matters

Chamilo LMS installations prior to version 1.11.30 are vulnerable to SQL injection attacks through the exercise hotpotatoes module, allowing authenticated or unauthenticated attackers to potentially extract sensitive data or compromise system integrity. Organizations using affected Chamilo versions should prioritize immediate patching to prevent unauthorized access to student records, course content, and institutional data.

Business Impact: High

Compensating Controls

Apply vendor patch. If immediate patching is unavailable: implement WAF rules to block POST requests to /main/exercise/hotpotatoes.php containing SQL injection patterns; restrict access to the exercise module via network segmentation; disable the HotPotatoes exercise feature if not in active use; monitor for suspicious database queries and authentication anomalies.
