Reflected XSS via unsanitized request path

Published Jan 9, 2020 · Updated Aug 5, 2024

Reflected XSS in the Digi Page of Digi AnywhereUSB 14 firmware 1.93.21.19 allows remote attackers to execute script via a crafted link. The embedded web server inserts an attacker-controlled request path containing HTML closing tokens and a script element into the Digi Page without neutralization. No authentication is required, but a user must follow the crafted link; script then runs in the browser's Digi Page context and can read or modify accessible page data.
