Vulnerability details
The vulnerability allows a remote user to compromise the affected system.
The vulnerability exists due to improperly imposed security restrictions when providing public access to the admin panel. A remote user with access to the admin panel and permission to open the "Editor" section can bypass the Safe Mode (cms.safe_mode) restriction and introduce new PHP code in a CMS template using a specially crafted request.
