CVE-2025-4994: Authentication Bypass for SafeLine SL6 and 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.

Security readout for executives and security teams

CVE-2025-4994 affects SafeLine SL6 and SL6+ elevator emergency intercom devices. An attacker physically near the device could use Bluetooth Low Energy to bypass authentication and access administrative configuration. This can affect safety-critical building communications, so owners should identify affected devices and seek vendor guidance promptly. Exposure is mainly locations with SafeLine SL6 or SL6+ devices running version 4.82 and BLE reachable from nearby public, tenant, maintenance, or equipment areas. The source states other versions are default unaffected, but organizations should verify exact firmware and vendor applicability. Treat as a high-priority facilities and safety-systems issue. The risk requires nearby access, but successful abuse could change emergency intercom configuration. Prioritize inventory and vendor remediation planning, especially in publicly accessible buildings. Mitigation focus: Inventory SafeLine SL6 and SL6+ devices in elevator emergency intercom deployments.; Identify devices running firmware version 4.82.; Check SafeLine or cited advisory guidance for updates or compensating controls..
