Summary

GetSimple CMS is a content management system (CMS), and GetSimple CMS CE is the community edition of that CMS. A logic flaw in GetSimple CMS (v3.4.0a and below) and GetSimpleCMS-CE (v3.3.22 and below) allows unauthenticated attackers to create a new administrator account. The application features an automated security control designed to delete the sensitive `admin/setup.php` file post-installation. However, this control is neutralized by a self-exclusion bug within the deletion logic, leaving the setup script accessible for unauthorized account creation even after a legitimate installation is completed. As of time of publication, no known patched versions are available.
