XSS (Cross Site Scripting)

XSS (Cross Site Scripting) is a technique which enables malicious attackers to inject client-side script into web pages viewed by users. It is a type of computer security vulnerability typically found in web applications. By doing so an attacker can gain elevated access privileges to sensitive page content, session cookies and a variety of other information maintained by the browser on behalf of the user.

XSS holes are web application vulnerabilities which allow attackers to bypass client-side security mechanisms, which is a significant security risk at client end. The attacker may gain access to valuable information and damage the whole security system. Often attackers will inject JavaScript, VBScript, ActiveX, HTML or Flash into a vulnerable application to fool a user in order to gather data from them.

XSS flaws or holes can be classified into non-persistent and persistent. Some sources further divide them into traditional and DOM-based. There are various techniques that can be used to control cross-site such as mitigation techniques (validation, escaping and filtering), cookie security, disabling scripts and so on.
