Cross-site scripting
Cross-site scripting or XSS is a web attack at application layer. XSS rather than targeting the script embedded in a page executed on the server side, it tagets the script executed on the client side. In XSS attack, the hacker injects some malicious script to do something bad in the web page. For more details visit the link http://findnerd.com/list/view/Cross-site-scripting/2076/
