CVE-2022-32508Public exploitNetwork attack vector

Unauthenticated reboot via malformed HTTP method

Published May 9, 2024 · Updated Feb 13, 2025

Denial of service in Nuki Bridge v1 before 1.22.0 and v2 before 2.13.2 allows remote attackers to reboot the device via HTTP. The HTTP API on TCP port 8080 emits three 405 responses and restarts after a non-GET method; NCC Group could not confirm the root cause but observed an infinite loop. The attack requires network reachability to the enabled Bridge HTTP API; no token or user interaction is required, and the bounded consequence is a temporary service interruption.
