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.
Authentication Bypass by Primary Weakness The authentication algorithm is sound, but the implemented mechanism can be bypassed as the result of a separate weakness that is primary to the authentication error.
