Executive brief
Croogo CMS, a content management system, contains a security flaw in its file management component. An authorized user with administrative access can bypass directory restrictions to create or modify files anywhere on the server's web directory. This could allow an attacker to upload malicious scripts and take full control of the website.
Technical details
A path traversal vulnerability exists in Croogo CMS up to version 4.0.7 within the Admin File Manager component. The root cause is located in `FileManager::isEditable` in `FileManager/src/Utility/FileManager.php`, which incorrectly uses `Configure::check()` instead of `Configure::read()`. This results in a boolean value being used for path validation instead of the actual allowed directory list, effectively failing to enforce directory boundaries. An authenticated attacker with access to the File Manager can exploit this via remote network requests to create or overwrite files outside of the intended `WWW_ROOT/assets` directory. If the attacker writes a PHP file to a web-accessible directory, this can lead to remote code execution (RCE). Exploitation requires a valid session and a CSRF token.
