Hi team,
While performing security testing of your website i have found the
vulnerability called Clickjacking.
Many URLS are in scope and vulnerable to Clickjacking.
What is Clickjacking ?
Clickjacking (User Interface redress attack, UI redress attack, UI
redressing) is a malicious technique of tricking a Web user into clicking
on something different from what the user perceives they are clicking on,
thus potentially revealing confidential information or taking control of
their computer while clicking on seemingly innocuous web pages.
The server didn't return an X-Frame-Options header which means that this
website could be at risk of a clickjacking attack. The X-Frame-Options HTTP
response header can be used to indicate whether or not a browser should be
allowed to render a page in a <frame> or <iframe>. Sites can use this to
avoid clickjacking attacks, by ensuring that their content is not embedded
into other sites.
This vulnerability affects Web Server.
Steps to Reproduce / POC

POC is in the attachments. Thanks, waiting for your response.
Impact
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 attackers
