## Overview

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.
