UI Redressing Mayhem: Firefox 0day and the LeakedIn affair

Mozilla had killed cross-domain drag and drop, so this post revives it by framing both the victim page and the attacker's dropper page as two iframes of one malicious page, a case Firefox 17.0.1 never checked. Applied to LinkedIn it drags out the csrfToken, adds an attacker email to the profile and confirms it over IMAP, yielding a full password reset.
