Session hijacking via stored RADIUS username script
Published Oct 22, 2021 · Updated Aug 4, 2024
Stored XSS in DrayTek VigorAP 1000C 1.3.2 allows remote authenticated users to execute scripts in a privileged user's browser. The RADIUS Server Configuration module stores the username field without neutralizing embedded HTML or script and renders it in the users profile view. A low-privileged account can plant the payload, but a more privileged user must open the module; execution can hijack that user's session or alter the page.
