mH-DEVELOPER smart home module uses the same hard-coded SSH host keys on every device, with no per-device key generation. An attacker who extracts these keys from the firmware can set up a rogue SSH server that clients will trust without warning, enabling man-in-the-middle attacks and credential interception.
This issue was fixed in versionĀ 3.0.30
