FKIE_CVE-2025-68719

Vulnerability from fkie_nvd - Published: 2026-01-08 21:15 - Updated: 2026-06-17 09:59
Severity
8.8 (High) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
KAYSUS KS-WR3600 routers with firmware 1.0.5.9.1 mishandle configuration management. Once any user is logged in and maintains an active session, an attacker can directly query the backup endpoint and download a full configuration archive. This archive contains sensitive files such as /etc/shadow, enabling credential recovery and potential full compromise of the device.
