Improper Restriction of Rendered UI Layers or Frames in kcal-app/kcal


Reported on

Sep 25th 2021

# Description
it can be possible to perform a clickjacking attack due to the lack of frame restrictions. The application does not set the response header X-Frame-Options: DENY.

 # Proof of Concept

        <title>Clickjack test page</title>
        <iframe src="" width="500" height="500"></iframe>

save the script as clickjacking .html and page will render in iframes

# Impact
 it is possible for a page controlled by an attacker to load the website within an iframe. This will enable a clickjacking attack, in which the attacker's page overlays the target application's interface with a different interface provided by the attacker

configure X-FRAME-OPTIONS  as same origin by default.
