CVE-2023-7017
Published: March 15, 2024· Updated: Jun 17, 2026
Official 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.
Risk Analysis
Sciener lock firmware fails to authenticate firmware updates sent via Bluetooth Low Energy, allowing an attacker to compromise the device. The 9.8 CVSS score reflects the critical nature of this unauthorized control risk.
No public exploit is known, and it is not in the KEV catalog. The flaw is remotely exploitable.
Users should check for firmware updates from the lock manufacturer and restrict physical or Bluetooth access to the devices.
Technical Analysis
CVE-2023-7017 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.
