XSS Ref: http://en.wikipedia.org/wiki/Cross-site_scripting
Cross-site scripting (XSS) is a type of computer security vulnerability typically found in web applications which allow code injection by malicious web users into the web pages viewed by other users. Examples of such code include HTML code and client-side scripts. An exploited cross-site scripting vulnerability can be used by attackers to bypass access controls such as the same origin policy. Recently, vulnerabilities of this kind have been exploited to craft powerful phishing attacks and browser exploits. Cross-site scripting was originally referred to as CSS, although this usage has been largely discontinued.
