How to hack websites using cross-site scripting (XSS)

In this episode of Full Disclosure we are explaining the website attack known as Cross-Site Scripting (XSS). Cross-Site Scripting is a type of security vulnerability that affects web applications that do not sanitize user input properly. This kind of vulnerability allows an "attacker" to inject HTML or client side script like JavaScript into the website. Cross-Site Scripting is most commonly used to steal cookies. Cookies are used for authenticating, tracking, and maintaining specific information about users; therefore, by stealing a user's cookies an attacker could bypass the website's access control. There are three types of XSS attacks: Persistent, Non-Persistent, and DOM-Based. In this episode we will cover Persistent and Non-Persistent Cross-Site Scripting attacks.
