Short explanation

Where the conditional path exists, the impact can lead to a full server compromise.
What should be done?
- Update Chamilo LMS to version 1.11.40, 2.0.1, or later
- Follow the vendor advisory for specific updates

Show the technical text from the sources
Chamilo LMS is an open-source learning management system. In the 1.x line before 1.11.40, and the 2.x line before 2.0.1, multiple `eval()` calls in the vendored PEAR `HTML_QuickForm` libraries can execute arbitrary PHP code if form element names contain attacker-influenced data. Standard Chamilo forms use hardcoded element names; exploitation requires a developer-specific plugin or misconfiguration that lets user input reach those element names. Where that conditional path exists, the impact can be full server compromise. This issue is fixed in versions 1.11.40 and 2.0.1.
