Publication date: 2026-08-14

Last updated on: 2026-08-14

Assigner: ICS-CERT

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.

Executive Summary

This is a critical OS command injection vulnerability in the Haiwell IoT Cloud HMI Gateway product. It exists in the Net Check feature via the /setting endpoint. The cmdPing Socket.io event does not properly sanitize user input before passing it to the OS, allowing attackers to inject and execute arbitrary commands with root privileges.

Detection Guidance

Detecting this vulnerability requires checking for the presence of Haiwell IoT Cloud HMI Gateway software and verifying its version. Inspect network traffic for connections to the /setting endpoint or Socket.io cmdPing events. Use commands like 'netstat -tuln | grep 80' to check for web server activity or 'curl -X POST http://<target>/setting' to probe the endpoint.

Impact Analysis

An attacker could exploit this to execute arbitrary OS commands with root privileges, potentially taking full control of the affected system. This could lead to unauthorized access, data theft, system disruption, or further network compromise in critical infrastructure sectors like Energy, Manufacturing, or Water systems.

Mitigation Strategies

Immediately update to the patched version Scada-v3.50.1.19 from Haiwell's website. Isolate the affected system from critical networks, restrict access via firewalls, and use VPNs for remote access. Disable the Net Check feature if not required and monitor for unusual command execution patterns.
