Opera Web Browser is prone to a security weakness that may permit malicious web pages to spoof address bar information. This issue is due to a race condition error.

This issue may be leveraged by an attacker to display false information in the address bar of an unsuspecting user, allowing an attacker to present web pages to users that seem to be derived from a trusted location. This may facilitate phishing attacks; attempted theft of user information for the purpose of identity theft.

<script>
function fake() {
 oc=window.open('http://www.opera.com/', '','location=1');
 oc.location.replace('http://www.example.com');
}
[/script]
<a href="javascript:void(0);" onClick="fake()">http://www.opera.com/</a>

- 漏洞描述

Opera contains a flaw that may allow a malicious user to spoof a trusted Web page. The issue is triggered when a remote attacker alters the opera address bar with the window.open and location.replace functions, which will load other page contents while keeping the URL. By crafting a specially-crafted web page, a remote attacker can spoof a trusted website to trick users into visiting a malicious Web site and possibly retrieve sensitive information, resulting in a loss of integrity.
