Vulnerability Report(UI Redressing)

Hey Team,



I am a security researcher. I have found the following bug in your site.(web)



Bug type : UI Redress

Impact :  Phishing (account compromise)



Description :

Clickjacking, also known as a "UI redress attack", is when an attacker uses 
multiple transparent or opaque layers to trick a user into clicking on a button 
or link on another page when they were intending to click on the the top level 
page. Thus, the attacker is "hijacking" clicks meant for their page and routing 
them to another page, most likely owned by another application, domain, or both.

 

Using a similar technique, keystrokes can also be hijacked. With a carefully 
crafted combination of stylesheets, iframes, and text boxes, a user can be led 
to believe they are typing in the password to their email or bank account, but 
are instead typing into an invisible frame controlled by the attacker.

 

POC:

 

<html>

<head></head>

<body>

<h1>WEBSITE IS VULNERABLE TO CLICKJACKING</h1>

<iframe width=100% height=80% src="https://bash-hackers.org";></iframe>

</body>

</html>

 

Impact: 

The site can also be opened in an iframe after the user has logged in making it 
hard for the user to avoid phishing.A user can be tricked into entering his 
credentials in  the placeholder for the original website details. And thus his 
credentials would be sent to the attacker.



Remediation :

Add an X-Frame-Options Header in the header of the website Or you can use 
"Content-Security-Policy" header to set frame rules.For more information you 
can visit this link.

Note:

I am attaching a screenshot as a POC. 



Hoping for a  bounty for responsibly disclosing this report to your website.



Waiting for your reply.

Regards
Syed Maaz
