Name of the Vulnerable Software and Affected Versions Chamilo LMS versions prior to 1.11.20

Description The issue concerns a path traversal vulnerability in the file upload functionality, specifically in the /main/webservices/additional webservices.php endpoint. This allows unauthenticated attackers to perform stored cross-site scripting attacks and obtain remote code execution via arbitrary file write.

Recommendations For versions prior to 1.11.20, update to a version that contains a fix for this issue to prevent path traversal and subsequent remote code execution. As a temporary workaround, consider restricting access to the /main/webservices/additional webservices.php endpoint to minimize the risk of exploitation.
