CVE-2024-43812

Password-hash disclosure via exposed passwd entries

Published Oct 22, 2024 · Updated Oct 23, 2024

Insufficient credential protection in Kieback&Peter DDC4000 controllers allows local unauthenticated attackers to read password hashes. The embedded system exposes every user's password hash through /etc/passwd instead of confining hashes to a protected credential store. Exploitation requires local access to that file; public sources do not disclose how such access is obtained or any direct network path.
