CVE-2025-66261: Dbbroadcast mozart next 100 firmware os command injection vulnerability

Dbbroadcast · Mozart Next 100 Firmware

Unauthenticated OS Command Injection (restore_settings.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 URL-decoded name parameter passed to exec() allows remote code execution. The `/var/tdf/restore_settings.php` endpoint passes user-controlled `$_GET["name"]` parameter through `urldecode()` directly into `exec()` without validation or escaping. Attackers can inject arbitrary shell commands using metacharacters (`;`, `|`, `&&`, etc.) to achieve unauthenticated remote code execution as the web server user.
