Unauthenticated code execution via unrestricted file upload

Published Nov 18, 2025 · Updated Nov 19, 2025

Unrestricted file upload in Mozart FM Transmitter WEBMOZZI-00287 allows remote attackers to execute commands through an HTTP request. The /upload_file.php endpoint accepts an unauthenticated PHP payload without file-type validation or sanitization and stores it under the web-accessible /upload/ directory. Accessing the uploaded script invokes the PHP interpreter, granting command execution with the permissions of the web service.
