Security company Secunia, has already issued two warnings on the latest version of Microsoft’s internet browser IE7.

The latest bug to the week old browser is described as “a vulnerability which can be exploited by malicious people to conduct phishing attacks”.

The problem occurs when IE 7 displays a popup with a spoofed address bar where a number of special characters have been appended to the URL. The characters disguide the real address and could possibly make users believe they were on an authentic site.

Secunia have created a demonstration of the vulnerability, which is available at here.
As yet there’s no patch for the vulnerability and Secunia recommend that users “do not follow links from untrusted sources.”

The previous vulnerability in IE7, discovered last week, was caused due to an error in the handling of URL redirections with the “mhtml:” URI handler, and could be exploited to access documents served from another web site.
The error appears to be an ongoing vulnerability, and has existed in all the previous versions of IE.
