AI-suggested
- 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.
- Disable the restore_settings.php functionality if it is not essential for operations until a patch is available.
- Monitor network traffic and device logs for suspicious requests containing shell metacharacters or unusual command patterns targeting the 'name' parameter.
- 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.
- Implement web application firewall (WAF) rules to detect and block command injection attempts targeting this endpoint.
- Conduct thorough security assessments of all Mozart FM Transmitter devices in use to identify any signs of compromise.
- Establish incident response plans specific to broadcast infrastructure to quickly contain and remediate potential exploitation.
- 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.
