CVE-2023-7017

Status: DeferredCritical (9.8)—

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.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
