Set apache header X-Frame-Options: "DENY"
The LEAP web application can be displayed inside other pages using an HTML
iframe. Therefore, an attacker can embed parts of the LEAP application inside
of a webpage they control. They can then use special style properties to
disguise the embedded page. By tricking a user in to clicking in the iframe, the
attacker can coerce the user in to performing unintended actions within the LEAP
web application.
An attacker creates a website that embeds the LEAP web application in an iframe.
They then create an HTML /JavaScript game on the same page that involves
clicking and dragging sprites. When a user plays the game, they are in fact
dragging new text values in to the ‘‘Change Password’’ form in the LEAP web app,
which is hidden behind the game using
As long as iframe embedding is not required in the normal usage of the
application, the X-Frame-Options header should be added to prevent browsers from
displaying the web application in frames on other origins.
This has also been set in the webapp
