CVE-2026-82929: F&F Filipowski mH-DEVELOPER hard-coded SSH host keys

CVE-2026-82929 · Severity: info · Published 2026-09-28

The mH-DEVELOPER smart home control module contains hard-coded SSH host keys identical across all devices, allowing an attacker who extracts these keys from the firmware to impersonate a trusted SSH server. This enables man-in-the-middle attacks where an attacker can intercept login credentials and commands controlling building automation systems, potentially gaining unauthorized access to heating, lighting, and other home functions.

Technical details

This vulnerability uses hard-coded cryptographic keys (CWE-321) in the SSH daemon that are shared across all devices and can be extracted from the firmware. An attacker with network access can deploy a rogue SSH server using these keys; clients will trust the server without certificate verification warnings. This permits credential theft and session hijacking of SSH connections.
