CVE-2023-7017

Complete takeover via unauthenticated firmware installation

Published Mar 15, 2024 · Updated Nov 4, 2025

Improper firmware validation in Kontrol Lux 6.5.x through 6.5.07 allows physically proximate attackers to install malicious firmware via BLE. A separate update service routes OTA packets to handle_ota_packet without requiring the normal check_admin challenge or authenticating the firmware image. Bluetooth range is sufficient, and successful installation gives attacker-controlled firmware full control of lock behavior.
