Upon IE7 release, Secunia published SA22477 titled `Internet Explorer 7 "mhtml:" Redirection Information Disclosure`. Here I figured a straightforward demo - navigate IE7 to: * mhtml:http://www.google.com/url?q=http://www.yahoo.com/ Google redirects to Yahoo, Yahoo content is loaded, but browser location is not updated. Microsoft blogs assure vulnerability brought up by Secunia is not in IE7, technically, rather, it's Outlook Express; and as usual, words of Microsoft were well honored by several public media sources. Microsoft do not even send the slightest comment that IE is a source of problem - despite there involves cross-domain data compromise, HTTP redirection, ActiveX(DOM also works) ... all in all, when this attack happens, it got to be IE and no other. Let me sum up: in this case IE is vulnerable, only IE is vulnerable, and Microsoft say "These reports are technically inaccurate: the issue concerned in these reports is not in Internet Explorer 7 (or any other version) at all". Upon seeing "mhtml:", it reminds of a magnificent historic incident which also involved "mhtml:" -- an IE exploit so perfectly and widely utilized that it made CERT suggest "Use a different web browser"(CERT KB VU#323070), and firstly initiated the boom of Firefox. Of course Microsoft is unlikely to say technically this is also not IE's problem. At last allow me to put an off-topic yet sentimental complain ... Quite a while ago, when I got IE exploits and Secunia broadcasted about them, my name was in every news report; This month same situation, codedreamer - original finder of the "mhtml:" thing broadcasted by Secunia - was not properly given credit ... no mentioning in news reports, no mentioning in the famous first ever IE7 advisory SA22477, codedreamer made the whole thing yet Secunia gave but one single line of credit in bottom of demo "The test is based on Proof of Concept code by codedreamer". Let me say I'm a man who believes in paying respect, thus I made this little complain, paying my respect to codedreamer. Best Wishes for All Firefox Surfers and Firefox 2.0 Liu Die Yu 25 OCT 06
