Vulnerability Details


This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of IBM Lotus iNotes. 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 dwa85W.cab ActiveX control.

This can be leveraged by an attacker to execute code under the context of the user running the browser.
