CVE-2022-32506

Firmware control via enabled SWD debug interface

Published May 9, 2024 · Updated Feb 13, 2025

Improper physical access control in Nuki Smart Lock and Bridge firmware allows physically proximate attackers to read or alter flash memory. Exposed Serial Wire Debug interfaces on the circuit board leave processor debugging enabled, permitting execution control and access to internal and external flash. Physical board access is required on Smart Lock 2.0 before 2.12.4, Smart Lock 3.0 before 3.3.5, Bridge 1.0 before 1.22.0, and Bridge 2.0 before 2.13.2.
