Technical details
An unrestricted file upload vulnerability exists in mjperpinosa stumasy within the `application/PHP/objects/updates/add_post.php` file. The root cause is a flawed validation logic in the `up_file_to_post` argument that uses an OR (||) operator when checking MIME types and file extensions. An attacker can bypass these checks by providing a malicious PHP file with a forged whitelisted MIME type (e.g., application/pdf). Because the application moves the uploaded file to a web-accessible directory (`documents/files/`) without sanitizing the filename or enforcing strict extension checks, the attacker can achieve Remote Code Execution (RCE) by directly requesting the uploaded PHP script. This vulnerability requires low-privileged user authentication and can be exploited remotely. No official patch has been released by the vendor.
