Root command execution via unfiltered getDetail credentials
Published Aug 24, 2026 · Updated Aug 24, 2026
Command injection in DrayTek VigorSwitch firmware before the listed fixes allows remote authenticated users to execute root commands. The getDetail function passes insufficiently filtered username and password fields into command execution. Administrative web-interface credentials are required; DrayTek confirms the code condition but reports no known practical trigger in deployed devices.
