'Name' => "HP Application Lifecycle Management XGO.ocx ActiveX SetShapeNodeType() Remote Code Execution",

'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.
