Quite an eyeopener. I'm a firm believer in the SAAS model and I've just started using Googledocs at our company. I'll be folowing this with special interest. Anyone know if these issues also known to effect the MS Office Live env or does MS do it different? Nice post xssniper. Quite an eyeopener.

Causing the browser to display sensitive content and pulling that sensitive content to an attacker controlled domain are two totally different things my friend. The second item is left as an exercise for the reader,but all the heavy lifting is already done for you... @Rosario – Ahhh… if only it were so easy.

Looking at your PoC I've noticed that a more simple CSRF can be used to steal contacts as the remote resourse is not token-protected: http://docs.google.com/contacts/data/contacts?thumb=true&groups=true&show=ALL&enums=true&psort=Name&max=900 (e.g using ) More, Adobe livedoc states that loading the crossdomain file from docs.google.com your application can access "only" to that domain...how can you access resource from mail.google.com domain? Is it the missing step? :-) Sad September for Google Security team…

I mean, the whole web requires JS.

I haven't tested it with Safari, but it should still work as I'm obeying all of Flash's cross domain rules. It seems that pulling cross domain content with a Flash Object loaded by Firefox is a little buggy. Some instances of Firefox require a refresh in order for the list to appear (which I built into the page). Is the page refreshing after 10 seconds in your browser?
