Title says it all.

Imagine this:

<!DOCTYPE html>
<html>
<head>
</head>
<body>
<iframe style="display:none" name="xxx"></iframe>
<form method='POST' action='http://MYPAGE.com/account/' target="xxx" id="xxx">
  <input type='hidden' name='xxxxxxx' value='yyyyyyyy'>
  <input type='submit' value='submit'>
</form>
<script>document.getElementById("xxx").submit()</script>
</body>

How can I disable an attack like that?

解决方案

Use the X-Frame-Options and set it to DENY or SAMEORIGIN. DENY will completely deny anybody from framing the page in an iframe and SAMEORIGIN will only allow the same origin to display the page in an iframe. See https://coderwall.com/p/kdv1hw for more information.
