CVE-2026-71906Network attack vector

Root command execution via setLan parameter injection

Published Aug 24, 2026 · Updated Aug 24, 2026

OS command injection in six DrayTek VigorAP models allows remote authenticated users to execute commands as root through setLan. The setLan function passes insufficiently validated lanIp and lanNetmask values into operating-system command execution. Administrative credentials for the web management interface are required, and DrayTek reports no demonstrated practical attack path.
