About the Product:
==================
UniBox is one of the most innovative and reliable Hotspot Controllers in
the market today. You can install UniBox to manage any sized WiFi
network without having to replace any existing infrastructure. With
UniBox, you don't need any other solution for managing WiFi access. It
comes packed with features so just one box is enough to handle all the
functions of WiFi hotspots.

Description:
============
An issue was discovered on Unibox U-50 with version Unibox 2.4 and
poterntially respected all other  devices. There is CSRF via
/tools/network-trace with resultant XSS due to  lack of csrf token and
user input validation.

Additional Information
======================
The web interface of the SMB Unibox  does not validate the csrftoken,and
the /tools/network-trace  page does not properly sanitize the
user input which leads to xss, By combining this two attack we can form
the XSRF request which leads to complete account takeover using XSRF.
