CVE-2023-50124Public exploit

Door unlocking via default-credential fingerprint replacement

Published Jan 11, 2024 · Updated Sep 3, 2024

Hard-coded credentials in Flient Smart Lock Advanced Firmware 1.0 allow physically proximate attackers to unlock the door. Default credentials on the lock's debug interface permit replacement of the fingerprint stored on the scanner, causing the substituted print to pass biometric authentication. Physical access to the appliance and its debug interface is required, and successful exploitation grants unauthorized door access.
