Descriptions

An OS command injection vulnerability exists in AVTECH IP camera, DVR, and NVR devices via the PwdGrp.cgi endpoint, which handles user and group management operations. Authenticated users can supply input through the pwd or grp parameters, which are directly embedded into system commands without proper sanitation. This allows for the execution of arbitrary shell commands with root privileges.

Existe una vulnerabilidad de inyección de comandos del sistema operativo en AVTECH IP camera, DVR, y NVR a través del endpoint PwdGrp.cgi, que gestiona las operaciones de administración de usuarios y grupos. Los usuarios autenticados pueden proporcionar información mediante los parámetros pwd o grp, que se integran directamente en los comandos del sistema sin la debida autorización. Esto permite la ejecución de comandos de shell arbitrarios con privilegios de root.
