AI Analysis
Technical Summary
CVE-2026-82932 describes an improper restriction of communication channels in the mH-DEVELOPER smart home module. The module failed to load firewall rules at startup, leaving critical services like SSH, HTTP, WebSocket, and Node-RED exposed on the LAN without any access control. This exposure allows any client on the same network to connect to these services. The vulnerability was addressed and fixed in version 3.0.30 of the product.
Potential Impact
The vulnerability allows any client on the local network to access all listening services on the device without restriction. This could lead to unauthorized access to services such as SSH and Node-RED, potentially enabling further compromise or unauthorized control of the smart home module. The CVSS 4.0 score is 5.3, indicating a medium severity impact.
Mitigation Recommendations
Users should upgrade mH-DEVELOPER to version 3.0.30 or later, where the issue has been fixed by properly loading firewall rules at startup. Until the upgrade is applied, the device remains exposed on the LAN. No additional vendor advisory states alternative mitigations or that no action is required.
