Name of the Vulnerable Software and Affected Versions YzmCMS version 3.7.1

Description The issue concerns an eval injection in a specific PHP file, allowing remote attackers to execute arbitrary code. This is achieved by sending PHP code in the POST data of a particular request to index.php?m=member&c=member content&a=init.

Recommendations For YzmCMS version 3.7.1, consider restricting access to the index.php?m=member&c=member content&a=init endpoint until a patch is available. Avoid using the eval function in the global.func.php file to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
