Until an official fix is available, restrict network access to the /setting endpoint and monitor for suspicious activity related to the cmdPing Socket.io event. Avoid exposing the affected version 3.40.1.12 to untrusted networks.
Description
A critical OS command injection vulnerability has been identified in the Haiwell IoT Cloud HMI Gateway product. The vulnerability exists in the Net Check feature accessible via the /setting endpoint. The cmdPing Socket.io event fails to properly sanitize user-supplied input before passing it to the underlying operating system, allowing an attacker to inject and execute arbitrary OS commands with root privileges.
