UI REDRESSING in craigk5n/webcalendar
Jun 25th 2022
The web application does not restrict or incorrectly restricts frame objects or UI layers that belong to another application or domain, which can lead to user confusion about which interface the user is interacting with.
Proof of Concept
1) Go to this URL: http://web.clickjacker.io/test?url=http:%2F%2Fwebcalendar.sourceforge.net%2Fdemo%2Flogin.php 2) Observe that the website is getting embeded in an Iframe. 3) Observe that the headers x-frame-options and content-security-policy frame ancestors are missing.
Users are tricked into performing all sorts of unintended actions are such as typing in the password, clicking on ‘Delete my account’ button, liking a post, deleting a post, commenting on a blog. In other words all the actions that a normal user can do on a legitimate website can be done using clickjacking.
