Description

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of EMC ApplicationXtender. 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 the WxSuperCtrl650.ocx ActiveX control. By manipulating a combination of the DisplayImageFile, AnnoLoad and AnnoSave methods, the vulnerable AnnoSave() method can enable an attacker to save arbitrary files inside arbitrary locations. The attacker is able to control the file extension and the creation path via a directory traversal issue. An attacker can leverage this vulnerability to execute code under the context of the process.
