This is a toy page thrown up to demonstrate how a cross-site request forgery attack would work. It was made for a Learn All The Nodes episode, and you can see that episode at http://www.learnallthenodes.com/episodes/34-anatomy-of-a-cross-site-request-forgery-attack.
Please make sure to protect your site from easy attacks like this!
In the episode, this page was served from totallylegitforum.com (not that I own the domain-- hooray for /etc/hosts).
This page includes an image whose source hits a dangerously-exposed action and also provides a form that tries to hit the same action.
The episode shows how to lock down these 2 vectors.
