CVE-2025-68716

Unauthenticated root command execution via passwordless SSH

Published Jan 8, 2026 · Updated Jan 8, 2026

Missing authentication in the SSH service on KAYSUS KS-WR3600 firmware 1.0.5.9.1 allows remote attackers on the LAN to execute commands as root. The default SSH service accepts a login to the root account without a password, while the management interfaces provide no supported way to disable SSH or require credentials. Any attacker with LAN access can obtain a full-privilege shell and read or alter configuration, execute commands, or interrupt the router.
