UI REDRESSING in alextselegidis/easyappointments
May 20th 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
Go to this URL: https://clickjacker.io/test?url=https:%2F%2Fdemo.easyappointments.org%2Findex.php%2Fuser%2Flogin
Observe that the website is getting embeded in an Iframe.
Observe that the headers x-frame-options and content-security-policy frame ancestors are missing.
X-FRAME-OPTIONS is a security header to prevent clickjacking
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.
is there any update on this?
Hello! Thanks for posting this. Although this is something the server maintainer can define on their servers, I still think that it is a good idea having it as part of the code. So I've added this in the develop branch and will ship it with the next stable release (1.5.0)
