CRITICAL 9.8EPSS 0.29%

Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (0.29%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

Sciener locks' firmware update mechanism do not authenticate or validate firmware updates if passed to the lock through the Bluetooth Low Energy service. A challenge request can be sent to the lock with a command to prepare for an update, rather than an unlock request, allowing an attacker to compromise the device.
