Name of the Vulnerable Software and Affected Versions CMS Made Simple version 2.2.13

Description The issue allows remote code execution via a specially crafted .php.jpegd JPEG file. This can be achieved by sending a file as application/octet-stream to the admin/moduleinterface.php endpoint, specifically using the m1 files[] parameter. The file does not need to be a valid JPEG, but it should contain PHP code.

Recommendations For CMS Made Simple version 2.2.13, consider restricting access to the admin/moduleinterface.php endpoint to minimize the risk of exploitation, and avoid using the m1 files[] parameter until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
