AI-suggested
1. Immediately restrict network access to the /var/tdf/restore_settings.php endpoint by implementing firewall rules or network segmentation to limit exposure to trusted management networks only. 2. Disable the restore_settings.php functionality if it is not essential for operations until a patch is available. 3. Monitor network traffic and device logs for suspicious requests containing shell metacharacters or unusual command patterns targeting the 'name' parameter. 4. Engage with DB Electronica Telecomunicazioni S.p.A. to obtain and apply official patches or firmware updates addressing this vulnerability as soon as they are released. 5. Implement web application firewall (WAF) rules to detect and block command injection attempts targeting this endpoint. 6. Conduct thorough security assessments of all Mozart FM Transmitter devices in use to identify any signs of compromise. 7. Establish incident response plans specific to broadcast infrastructure to quickly contain and remediate potential exploitation. 8. Educate operational technology (OT) and IT teams on the risks and detection methods related to this vulnerability.
Description
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.
