CVE-2025-4994 (GCVE-0-2025-4994)

Vulnerability from cvelistv5 – Published: 2026-06-22 08:10 – Updated: 2026-06-22 12:25

Title

Authentication Bypass for SafeLine SL6 and SL6+

Summary

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.

Severity

8.7 (High)
