  I did not test that, but I think some routers use HTML forms to log in to 
the admin panel.  In this case, you should be able to use CSRF with AJAX xhr 
objects, or simple Javascript to auto-submit the form.  Once the browser is 
logged in, it could use the same process and submit forms to change 
configuration settings such as DNS servers (for this attack) and more.
