Description

Unauthenticated OS Command Injection (start_upgrade.php) in DB Electronica Telecomunicazioni S.p.A. Mozart FM Transmitter versions 30, 50, 100, 300, 500, 1000, 2000, 3000, 3500, 6000, 7000 allows an attacker to perform User input passed directly to exec() allows remote code execution via start_upgrade.php. The `/var/tdf/start_upgrade.php` endpoint passes user-controlled `$_GET["filename"]` directly into `exec()` without sanitization or shell escaping. Attackers can inject arbitrary shell commands using metacharacters (`;`, `|`, etc.) to achieve remote code execution as the web server user (likely root).
