A critical OS command injection vulnerability has been identified in the Haiwell IoT Cloud HMI Gateway product. (CVE-2026-19188)
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.
AI Analysis
Technical Summary
CVE-2026-19188 is a critical OS command injection vulnerability in the Haiwell IoT Cloud HMI Gateway product. It arises from improper sanitization of user-supplied input in the cmdPing Socket.io event within the Net Check feature at the /setting endpoint. This allows remote attackers to inject and execute arbitrary operating system commands with root privileges. The vulnerability has a CVSS 3.1 base score of 10.0, reflecting its critical impact and ease of exploitation without authentication or user interaction. No patch or remediation details are currently available.
Potential Impact
Successful exploitation enables remote attackers to execute arbitrary OS commands with root privileges on the affected device, leading to full system compromise. This can result in complete loss of confidentiality, integrity, and availability of the system.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to the /setting endpoint and the Net Check feature, and monitor for suspicious activity related to the cmdPing Socket.io event. Avoid exposing the affected service to untrusted networks.
