Description
The SafeLine SL6 and SL6+ devices integrated into elevator emergency intercom systems are vulnerable to an authentication bypass. This vulnerability allows attackers to bypass authentication requirements and access the device's configuration service via the Bluetooth Low Energy (BLE) interface. Consequently, an attacker within wireless range can gain unauthorized administrative access to the device configuration.

Remediation

Vendor Solution

A patch is available in firmware version 4.97 and should be applied immediately. This version removes the PIN authentication feature in BLE entirely. Access to the configuration interface via Bluetooth is only possible for a brief time window following a reboot, which is similar to the current behavior when disabling "Auto Enable BLE".


Vendor Workaround

The "Auto Enable BLE" setting should be disabled. This ensures that the BLE interface is deactivated after the initial time window, preventing wireless access to the configuration interface.
