Mozilla's Firefox 2 and Microsoft's Internet Explorer 7 are vulnerable to a flaw

Posted by firecad2006 on Mon, 11/27/2006 - 19:42For the Record

Dubbed a reverse cross-site request, or RCSR, vulnerability by its discoverer, Robert Chapin, the flaw lets hackers compromise users' passwords and usernames by presenting them with a fake login form. Firefox Password Manager will automatically enter any saved passwords and usernames into the form.

This is more of a flaw in the website that implements an app the way they've done it at MySpace (since fixed by MySpace). If you write a sloppy website, bad things can happen.

I guess by the same token, vulnerabilities in system ActiveX controls that allow websites to break into the system aren't really flaws in IE.

It is a flaw in Firefox.  It's an input validation problem: the password manager is not being as careful as it could be to validate that the form it's filling out is the form it should be filling out.  This is evidenced by the fact that IE is vulnerable to the same attack, but in a much narrower range of cases.

And the fact that it can steal passwords without user interaction should be cause for concern, not denial.

dont get too excited zatch... its simply saying that if you have passwords saved in your password manager, and you reach a website that can successfully request those passwords but is not the actual site, then they can have access to them.

 this is true with any password manager on any browser to my knowledge

A fake form on the real website can steal passwords.

But it does have to be on the real website -- a third-party phishing site wouldn't be able to do it.
