AI Analysis
Technical Summary
The Haiwell IoT Cloud HMI Gateway version 3.40.1.12 contains a critical OS command injection vulnerability (CWE-78) in its Net Check feature accessible via the /setting endpoint. The cmdPing Socket.io event fails to sanitize user-supplied input, enabling attackers to inject and execute arbitrary OS commands with root privileges. This vulnerability has been assigned CVE-2026-19188 and carries a CVSS 3.1 base score of 10. No official patch or remediation level has been published as of the data provided.
Potential Impact
Successful exploitation allows an unauthenticated attacker to execute arbitrary operating system commands with root privileges on the affected device. This can lead to full system compromise, including confidentiality, integrity, and availability impacts rated as high. The vulnerability is remotely exploitable over the network without user interaction.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. 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.
