ToorCon 9: URI use and abuse
posted Oct 21st 2007 8:50pm by Eliotfiled under: misc hacks
[Nathan McFeters] and [Rob Carter] gave a presentation on the problems with URI handling. URIs are used to send commands to external applications from a web browser. itms:// for iTunes for example. Any application that registers a URI has the potential to be abused through this route. For their first example they showed a stack overflow in Trillian’s AIM handling. The next demo created a “Critical Update Available” button on Picasa’s interface. When the user clicked it, their photos would be uploaded to the attacker’s server. They even display a “download progress” bar to encourage the user to keep the connection open. You can read about the attack on cocontributor Billy Rios’s blog.
