EXPLOITATION - XSS VULNS

XSS - CROSS SITE SCRIPTING VULNS

• Allow an attacker to inject javascript code into the page.
• The code is executed when the page loads.
• The code is executed on the client machine, not the server.

Three main types:

1. Persistent/Stored XSS.

2. Reflected XSS.

3.DOM-based XSS

 

DISCOVERING XSS

• Try to inject javascript code into the pages.
• Test text boxes and URL parameters on the form
  • 　　http://target.com/page.php?something=something

REFLECTED XSS

• None persistent, not stored.
• Only work if the target visits a specially crafted URL
  • 　　http://target.com/page.php?something=<script>altert("XSS")</script>

 

 

STORED XSS

• Persistent, stored on the page or DB.
• The injected code is executed every time the page is loaded.
