For almost two years, Microsoft's Internet Explorer browser has been vulnerable to attacks that steal digital security tokens and other sensitive data, a security researcher said recently.

Researcher Chris Evans said he alerted Microsoft to the information disclosure vulnerability in IE in December 2008. As of October 21, it remained unfixed, making his disclosure a “600-day” vulnerability, he quipped.

“There are a varied number of text structures which can be stolen (iteratively if necessary) with this trick,” Evans warned.

Firefox was once vulnerable to similar attacks but maintainers of the open-source browser fixed the flaw in December 2008. That was the same month Microsoft was informed of the vulnerability, but it has been allowed to remain.

A Microsoft spokeswoman on Monday issued the following statement, which she attributed to Jerry Bryant, a spokesman for Microsoft response:

"Microsoft is aware of the public posting of a low severity information disclosure issue in Internet Explorer. A successful attack requires a victim website to be configured in a specific way which is non-standard for most sites. We are not aware of any attacks seeking to exploit this issue and will update customers if that changes." ®
