CVE-2021-31655Public exploitNetwork attack vector

Script execution via reflected profile parameter

Published Aug 10, 2021 · Updated Jul 9, 2026

Reflected XSS in TRENDnet TV-IP110WN firmware 1.2.2.64, 1.2.2.65, and 1.2.2.68 allows remote attackers to run script via view.cgi. The /admin/view.cgi handler reflects the profile GET parameter into an HTML response without neutralizing script markup. Exploitation requires a victim to follow the crafted request and execute the reflected payload in a browser, enabling actions or data access within the camera web interface under that victim's session.
