CVE-2022-45045 Information

Description

Multiple Xiongmai NVR devices including MBD6304T V4.02.R11.00000117.10001.131900.00000 and NBD6808T-PL V4.02.R11.C7431119.12001.130000.00000 allow authenticated users to execute arbitrary commands as root as exploited in the wild starting in approximately 2019. A remote and authenticated attacker possibly using the default admin:tlJwpbo6 credentials can connect to port 34567 and execute arbitrary operating system commands via a crafted JSON file during an upgrade request. Since at least 2021 Xiongmai has applied patches to prevent attackers from using this mechanism to execute telnetd.
