CVE-2025-4994: CWE-305 Authentication bypass by primary weakness in SafeLine SafeLine SL6/SL6+
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.
AI Analysis
Technical Summary
CVE-2025-4994 is an authentication bypass vulnerability (CWE-305) in SafeLine SL6 and SL6+ devices used in elevator emergency intercom systems. The vulnerability enables attackers to bypass authentication controls and access the device's configuration service over Bluetooth Low Energy (BLE). This allows unauthorized administrative access to the device configuration by any attacker within wireless range. The vulnerability affects SafeLine SL6/SL6+ version 4.82. No official patch or remediation has been published by the vendor as of the data provided.
Potential Impact
An attacker within wireless range can bypass authentication and gain administrative access to the device configuration via BLE. This unauthorized access could allow manipulation of device settings, potentially impacting elevator emergency communication reliability and safety. The vulnerability has a high CVSS score of 8.7, indicating a significant security risk.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no official fix or mitigation is indicated, organizations should monitor vendor communications for updates. Until a patch is available, restricting physical and wireless access to the devices and disabling BLE if possible may reduce exposure.
