New IE7 bug exposes users to content injection

Powered by SC Magazine
 

Security researchers at Secunia have discovered a new vulnerability in Internet Explorer 7 that could be exploited by online identity thieves.

An attacker could inject content into another website's window, for instance replacing a log-in pop-up window for an online bank with a page that looks similar to the bank's log-in window.

The attacker would have to know the target name of the window being replaced, and would require the attacker's website and the target website to be open at the same time.

Secunia rated the vulnerability as 'moderately critical', its third most severe security rating on a five-step scale.

A Microsoft spokesman denied that the reported flaw describes a vulnerability in its software.

The said in an emailed statement that Secunia describes the issue as "a by-design behaviour in popular web browsers that allows a website to open or reuse a pop-up window".

Users will be able to tell that they have been directed to a phishing website because the pop-up window displays an address bar.

Secunia issued a warning about a similar vulnerability in Internet Explorer 5 and 6 in 2004.

Today's alert is the fourth alleged security vulnerability that Secunia has unearthed in Internet Explorer 7 since the browser was launched earlier this month.

In addition to today's denial, Microsoft has dismissed one other Secunia report because it affected Outlook Express rather than IE7. Microsoft has confirmed the two other vulnerabilities.
