What is CVE-2025-66261?

The Mozart FM Transmitter by DB Electronica Telecomunicazioni is susceptible to an unauthenticated OS command injection vulnerability. This issue arises from the improper handling of user input in the restore_settings.php script, specifically in the $_GET['name'] parameter, which is passed to the exec() function via urldecode() without any form of validation or escaping. This flaw permits attackers to inject arbitrary shell commands, enabling remote code execution as the web server user, thereby compromising the integrity and security of the system.
