This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of WebGate eDVR Manager. 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 WESPEvent.WESPEventCtrl.1 control. The Connect, ConnectEx, and ConnectEx2 methods copy arbitrary data to a fixed-size heap buffer. This would allow an attacker to execute arbitrary code in the context of the browser.
