An issue has been discovered in MS Outlook (All Versions) where anyone can fake a URL & send it across. How does it work: Lets compose an email in MS Outlook, lets type http://www.cybertrion.com & put a space after it to make it a link. Now put your cursor just before cybertrion & type any URL for eg: http://www.foo-labs.info now send it to anyone. The receiver will see the URL as http://www.foo-labs.info but when he clicks on it it will directly take him to http://www.cybertrion.com I am not sure how critical this is but it can fool alot of people & result in download of a virus.
Wow. MS really fucked up on this one. FYI, though, I've confirmed this vulnerability on Outlook 2003, IE6, and, shockingly, Mozilla Thunderbird, Firefox, Opera, and Safari. In fact, it almost seems as if *every* browser or other application that renders HTML has this "feature" of displaying the text inside a <a> tag! I, for one, am shocked and apalled that anyone could be so irresponsible as to write such a vulnerability into production code. By allowing links in their HTML pages, application writers make it trivially easy to trick viewers into visiting web sites they didn't intend to! This can lead to phishing attacks, viruses, widespread panic, and mass hysteria! Severity ranking: High! PS: If you weren't talking about just changing the link text, I apologize for the above sarcasm. -- Dan _______________________________________________ Full-Disclosure - We believe in it.
