CVE-2023-25946

Unauthenticated lock operation via Bluetooth command replay

Published May 23, 2023 · Updated Jan 31, 2025

Authentication bypass in Qrio Lock Q-SL2 firmware 2.0.9 and earlier allows network-adjacent attackers to perform unintended operations. The lock's Bluetooth Low Energy communication accepts previously captured valid command data when replayed instead of ensuring each authenticated command is used only once. Attackers must be within Bluetooth range and capture usable communication data; Qrio has not disclosed the additional conditions governing successful lock operation.
