CVE-2025-66261Public exploitNetwork attack vector

Unauthenticated command execution via decoded name parameter

Published Nov 26, 2025 · Updated Nov 26, 2025

OS command injection in DB Elettronica Mozart FM Transmitter allows remote attackers to execute shell commands through its web interface. The unauthenticated restore_settings.php endpoint URL-decodes its name parameter and appends the result directly to an exec() command without validation or shell escaping. Shell metacharacters therefore execute commands as the web server user, permitting compromise of the transmitter's embedded environment.
