Name of the Vulnerable Software and Affected Versions Tapplock devices versions prior to 2018-06-12

Description The issue concerns the Bluetooth Low Energy (BLE) subsystem, which relies on Key1 and SerialNo for unlock operations. However, these are derived from the MAC address, which is broadcasted by the device.

Recommendations For versions prior to 2018-06-12, consider restricting access to the BLE subsystem until a fix is available. As a temporary workaround, avoid using the BLE unlock feature to minimize the risk of exploitation.
