What is CVE-2025-34056?

An OS command injection vulnerability is present in AVTECH IP cameras, DVRs, and NVR devices, specifically through the PwdGrp.cgi endpoint, which handles user and group management. When authenticated users interact with the pwd or grp parameters, their input is integrated directly into system commands without adequate validation. This significant oversight enables unauthorized execution of arbitrary shell commands with root-level privileges, posing a substantial risk to device integrity and security.
