The web application running on the remote web server is affected by a cross-site scripting vulnerability.


A cross-site scripting (XSS) vulnerability exists in OpenWrt web user-interface due to improper validation of user-supplied input before returning it to users. An unauthenticated, remote attacker can exploit this, by convincing a user to click a specially crafted URL, to execute arbitrary script code in a user's browser session.
