The following is a summary from the orginal post on the solution to exploit the router:

It was found by the author, in order to get a successful remote exploit, one must:

- Control of timing between requests

- To still have control of the page the user loaded, even if the form navigates to a target.

- No popups

- Little, if any, indication to the user that their router is being owned

The author implements a attack that not clean but effective. The exploit can be performed using any default browser without any other tools . By setting each form target to a different frame and using a 3-part payload, he was able to exploit the router's CSRF vulnerability.
