Example: http://[victim]/openautoclassifieds/friendmail.php?listing=<script>alert(document.domain);</script> The vulnerability has been confirmed in version 1.0. Solution: Filter malicious input in a HTTP proxy or firewall with URL filtering capabilities. Edit the source code to ensure that user input is properly validated.
