Hey Robin,
You shouldn't worry about GET or POST. A CSRF will happen in both
places. Its just that the GET is easier and more visible.

For a POST you could either use OWASP's CSRF Tester to record and
replay a request. Or you could create a HTML page manually with all
hidden variables and just a button as a POC.

It is this bit I was after info on, I could think of a way that I
would attempt a POST but wanted to see research others had done.

As it turns out I've had quite a few good leads passed across, thanks
to everyone. Most work in a similar way but all have slight variations
that are useful to know about when trying to work out the best way to
attack a target.

Robin


Cheers
Arvind

Hi
Can anyone point me at any good papers on doing CSRF through POST
parameters? I've found some sites with redirect scripts which help
performing the attack but no good write-ups on different ways to
perform it.
