Firefox: seven-year-old security hole once again

by Nikola Strahija on June 8th, 2005 New versions of the Mozilla Firefox have re-introduced a seven-year-old flaw that makes them vulnerable to spoofing attacks, said Secunia.


Secunia first publicised the flaw last summer, warning that a feature that had been built into most browsers for years was in fact a security liability.

The firm argued that a feature allowing one Web page to load arbitrary content into a frame of another page could allow an attacker to, for example, substitute his own login window on a bank's website. The feature was found in IE, Mozilla, Opera, Safari and Mozilla derivatives such as Konqueror.

Most browser vendors, including Mozilla, agreed the problem was serious and updated their products to remove the feature. But it has been re-introduced in Firefox 1.0.4, Mozilla 1.7.8 and Camino 0.x, according to the firm.

The new vulnerability is a slight variation of the flaw fixed last year, Secunia said.

The Mozilla Project said it is investigating the report, and a moderator of the organisation's online support site said the flaw had not been exploited. "To protect yourself, close all other windows/tabs before accessing a site where you routinely put in a secure password (your bank or PayPal account), or your bank or credit card details (e.g. Amazon), or other sensitive data," the moderator said.
