CVE-2025-34055
Estado: AplazadaCrítica (9.4)—
An OS command injection vulnerability exists in AVTECH DVR, NVR, and IP camera devices within the adcommand.cgi endpoint, which interfaces with the ActionD daemon. Authenticated users can invoke the DoShellCmd operation, passing arbitrary input via the strCmd parameter. This input is executed directly by the system shell without sanitation allowing attackers to execute commands as the root user.

"value": "An OS command injection vulnerability exists in AVTECH DVR, NVR, and IP camera devices within the adcommand.cgi endpoint, which interfaces with the ActionD daemon. Authenticated users can invoke the DoShellCmd operation, passing arbitrary input via the strCmd parameter. This input is executed directly by the system shell without sanitation allowing attackers to execute commands as the root user."

Los usuarios autenticados pueden invocar la operación DoShellCmd, pasando una entrada arbitraria mediante el parámetro strCmd. Esta entrada es ejecutada directamente por el shell del sistema sin sanear, lo que permite a los atacantes ejecutar comandos como usuario root."
