Drupal security: video example of user account hijacking with XSS

In this short screencast a variety of security holes are shown, as well as some malicious things which are made possible due to these lapses. We'll take a walk-through of two security issues showcased in the vulnerable.module, as well as two other exploits which I put together:
  • User account hijacking via cookie/session XSS thievery
  • User account hijacking via password-changing-inline-XSS

It's worth noting that in the screencast we demonstrate security exploits in the context of a Drupal installation which uses custom code (e.g., the examples in the video do not represent actual vulnerabilities in Drupal core). Likewise, these exploits and security holes potentially apply to any web site, Drupal or not, which accepts user input.
