An unauthenticated attacker may set the contents of the /mnt/jffs2/banner.txt file, stored on the device's filesystem, to contain arbitrary JavaScript. The file contents are then used as part of a welcome/banner message presented to unauthenticated users who visit the login page for the web console.
