CRITICAL 9.8

DescriptionGitHub Advisory

Chamilo is a learning management system. Prior to version 1.11.30, there is an error-based SQL Injection via the GET openid.assoc_handle parameter with the /index.php script. This issue has been patched in version 1.11.30.

Executive ViewAI

Why It Matters

Chamilo LMS installations running versions prior to 1.11.30 are vulnerable to critical SQL injection attacks through the OpenID authentication parameter, allowing attackers to extract sensitive data, compromise user accounts, and potentially gain system access. Organizations using Chamilo must immediately assess their deployment versions and apply patches to prevent active exploitation.

Business Impact: Severe

Compensating Controls

Apply vendor patch. If immediate patching is delayed, implement WAF rules to block SQL injection payloads in the openid.assoc_handle parameter; restrict external access to /index.php until patching is complete; monitor authentication logs for SQL error messages or unusual OpenID requests; consider disabling OpenID authentication if not operationally required.
