This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of UCanCode E-XD++ Visualization Enterprise Suite. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within processing of the AddShapeWithoutUndo method within the UCCVIEWER.UCCViewerCtrl.1 ActiveX control. The process does not properly validate a user-supplied value prior to dereferencing it as a pointer. An attacker can leverage this vulnerability to execute arbitrary code under the context of the process.
