Original Release date: 07 Jun 2001 | Last revised: 07 Jun 2001


A vulnerability exists in Microsoft Internet Explorer which could could enable an attacker to spoof trusted web sites.


A vulnerability exists in Microsoft Internet Explorer. This vulnerability could enable a web page to display the URL
from a different web site in the IE address bar. This spoofing could occur within a valid SSL session with the impersonated site, meaning that a web site operator could make it appear that the content from his or her Web site actually originated from another site, even a trusted or secure Web site, when in fact, it did not.

More information on this problem is available from Microsoft at:


This vulnerability could be used to convince a user that the intruder's web site was actually a different one - a web site that the user
trusts and might provide sensitive information to.
