Name of the Vulnerable Software and Affected Versions Subrion CMS version 4.2.1

Description The issue allows remote attackers to execute arbitrary PHP code via a .pht or .phar file. This is because the .htaccess file omits these file types, specifically affecting the /panel/uploads endpoint.

Recommendations For Subrion CMS version 4.2.1, consider updating the .htaccess file to include .pht and .phar files to prevent arbitrary PHP code execution. As a temporary workaround, restrict access to the /panel/uploads endpoint to minimize the risk of exploitation.
