Name of the Vulnerable Software and Affected Versions Chamilo LMS versions prior to 1.11.24

Description The issue allows authenticated attackers with a learner role to achieve remote code execution. This is possible due to an unrestricted file upload in the /main/inc/ajax/work.ajax.php endpoint, which enables the uploading of PHP files.

Recommendations For versions prior to 1.11.24, update to a version that contains a fix for this issue. As a temporary workaround, consider restricting access to the /main/inc/ajax/work.ajax.php endpoint to prevent exploitation.
