CVE-2022-50791Public exploit

Command execution via crafted .ping.pid file

Published Dec 30, 2025 · Updated Dec 30, 2025

Command injection in affected SOUND4 appliance firmware allows remote attackers to execute operating-system commands through ping.php. The script processes a .ping.pid file in /tmp as commands, then deletes that file after the single HTTP POST request triggers it. Exploitation first requires a local authenticated user to place the specially named command file; the remote trigger itself requires no authentication.
