Critical Firefox hole allows password theft

[Jordan]

November 23, 2006 (IDG News Service) -- A flaw in Mozilla Corp.'s Firefox browser makes it easy for cybercriminals to steal user information on Web sites where users create their own pages, such as MySpace.com.
The flaw lies in Firefox's Password Manager software, which can be tricked into sending password information to an attacker's Web site, said Robert Chapin, president of Chapin Information Services Inc. For this attack to work, attackers need to be able to create HTML forms on the Web site, which is allowed on blogging and social networking sites.


The attack was used in a MySpace phishing attack reported in late October. In that attack, users registered a MySpace account named login_home_index_html and used it to host a fake log-in page that exploited the flaw.


This page sent MySpace username and password information to another Web site, and MySpace users who visited the page using Firefox could have easily had their information compromised, said Chapin.


Firefox developers rate this bug critical, according to an entry in the project's Bugzilla database.


The flaw arises because Firefox's Password Manager does not perform a thorough enough check when deciding whether to send password information and then does not ensure that password information is being sent to the server that requested it, Chapin said. In the MySpace attack, for example, Firefox would check to see if the form was coming from the MySpace.com domain but did not make sure that the password information was being sent back to a MySpace server.

Not good.... Not good at all... So they didn't state a fix for it...

Is this in the version of 2.0? dam it.. what about a fix?
Dam I'm gonna delete the saved passwords NOW!
EDIT:-
Yes its 2.0 ( I found it on a site )

Yes, this is 2.0 and no, there is no fix right now. Best thing you can do is not save your passwords in the manager.
