CVE-2026-82929Network attack vector

Credential interception via shared SSH host keys

Published Sep 28, 2026 · Updated Sep 28, 2026

Shared SSH host keys in F&F Filipowski mH-DEVELOPER before 3.0.30 allow attackers to impersonate devices and intercept credentials. The controller firmware uses the same SSH server host key on every unit instead of generating a device-specific key. An attacker must obtain the private key from firmware and occupy a client's connection path; the described consequence is trust in a rogue SSH server, not direct compromise of the controller.
