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

Description The issue concerns improper neutralisation of special characters, allowing command injection in the main/lp/openoffice presentation.class.php file. This enables users who are permitted to upload Learning Paths to obtain remote code execution.

Recommendations For versions prior to 1.11.24, update to a version that contains a fix for this issue to prevent remote code execution. As a temporary workaround, consider restricting access to the main/lp/openoffice presentation.class.php file or disabling the upload of Learning Paths until a patch is available.
