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).

Executive Summary

This vulnerability is an unauthenticated OS command injection in the start_upgrade.php script of DB Electronica Telecomunicazioni S.p.A. Mozart FM Transmitter devices. The script takes user input from the 'filename' GET parameter and passes it directly to the exec() function without any sanitization or escaping. This allows an attacker to inject arbitrary shell commands using metacharacters, leading to remote code execution on the device with the privileges of the web server user, which is likely root.

Impact Analysis

An attacker can exploit this vulnerability to execute arbitrary commands on the affected device remotely without authentication. This can lead to full compromise of the device, unauthorized access, data theft, disruption of services, or use of the device as a foothold for further attacks within the network.
