Hello,

it is possible to load
"https://www.facebook.com/login/reauth.php?next=https://www.facebook.com/confirmphone.php&display=popup"
in another page.

See here:

// Clickjacking test only
http://darksecurity.de/fb-clickjack/ClickJacking-iFrame.html

Here is a PoC for the login site: (I've used
http://code.google.com/p/javascript-keylogger/)

// X-Frame-Options on Facebook.com

My question: is this really not a security problem on Facebook?

Kind regards,
Stefan
