Summary
A remote command injection vulnerability exists in Vacron Network Video Recorder (NVR) devices v1.4 due to improper input sanitization in the board.cgi script. The vulnerability allows unauthenticated attackers to pass arbitrary commands to the underlying operating system via crafted HTTP requests. These commands are executed with the privileges of the web server process, enabling remote code execution and potential full device compromise. Exploitation evidence was observed by the Shadowserver Foundation on 2025-02-06 UTC.
