What is CVE-2025-34055?

An OS command injection vulnerability exists within AVTECH DVR, NVR, and IP camera devices, specifically at the adcommand.cgi endpoint interfacing with the ActionD daemon. This vulnerability allows authenticated users to invoke the DoShellCmd operation, executing arbitrary commands by passing unvalidated input through the strCmd parameter. Consequently, this input is processed directly by the system shell, enabling potential attackers to execute commands with root privileges, posing significant security risks to the affected devices.
