CRITICAL 9.8

DescriptionGitHub Advisory

Chamilo is a learning management system. Prior to version 1.11.28, parameter from SOAP request is evaluated without filtering which leads to Remote Code Execution. This issue has been patched in version 1.11.28.

Executive ViewAI

Why It Matters

Chamilo LMS installations prior to version 1.11.28 contain a critical remote code execution vulnerability that allows unauthenticated attackers to execute arbitrary commands on affected servers. Organizations using Chamilo for employee training, student management, or compliance purposes face immediate risk of system compromise, data theft, and operational disruption until remediation is completed.

Business Impact: Severe

Compensating Controls

Disable or restrict SOAP API access via network segmentation and firewall rules if the feature is not required; implement Web Application Firewall rules to inspect and filter SOAP request parameters for code execution patterns; enable comprehensive logging and monitoring of all SOAP requests; consider running Chamilo in a restricted container or isolated network segment; restrict administrative access to Chamilo servers; implement intrusion detection signatures for CVE-2025-50187 exploitation attempts.
