ChurchCRM is an open-source church management system. In versions prior to 7.2.0, the database backup restore functionality extracts uploaded archive contents and copies files from the Images/ directory into the web-accessible document root using recursiveCopyDirectory(), which performs no file extension filtering. An authenticated administrator can upload a crafted backup archive containing a PHP webshell inside the Images/ directory, which is then written to a publicly accessible path and executable via HTTP requests, resulting in remote code execution as the web server user. The restore endpoint also lacks CSRF token validation, enabling exploitation through cross-site request forgery targeting an authenticated administrator. This issue has been fixed in version 7.2.0.
