Un periodaccio per Apple: ora si scopre che Safari è bacato

via Jeremiah Grossman

Right at the moment a Safari user visits a website, even if they’ve never been there before or entered any personal information, a malicious website can uncover their first name, last name, work place, city, state, and email address. Safari v4 & v5, with a combined market browser share of 4% (~83 million users), has a feature (Preferences > AutoFill > AutoFill web forms) enabled by default. Essentially we are hacking auto-complete functionality.

This feature AutoFill’s HTML form text fields that have specific attribute names such as name, company, city, state, country, email, etc.

I figured Apple might appreciate a vulnerability disclosure prior to public discussion, which I did on June 17, 2010 complete with technical detail. A gleeful auto-response came shortly after, to which I replied asking if Apple was already aware of the issue. I received no response after that, human or robot. I have no idea when or if Apple plans to fix the issue, or even if they are aware, but thankfully Safari users only need to disable AutoFill web forms to protect themselves.
