CVE-2023-7003Public exploit

Unauthorized lock access via reused keypad key

Published Mar 15, 2024 · Updated Nov 4, 2025

Key reuse in Sciener TTLock and Kontrol Lux through 6.5.07 allows physically proximate attackers to unlock devices over Bluetooth. The wireless-keypad pairing handler decrypts every initialization request with the same hard-coded AES key, accepts the SCIENER marker, and registers the sender as a new keypad. Exploitation requires Bluetooth proximity and a lock supporting wireless keypads, but requires neither user interaction nor prior pairing.
