Tracing out Cross Site Scripting Vulnerabilities in Modern Scripts

Web Technologies were primarily designed to cater the need of ubiquitousness. The security concern has been overlooked and such overlooks resulted in vulnerabilities. These vulnerabilities are being highly exploited by hackers in various ways to compromise security. When vulnerability is blocked, the attacker traces out a different mechanism to exploit it. Cross site scripting (XSS) attack is also an exploitation of one of the vulnerabilities existing in the web applications. This paper traces out the vulnerability in functions and attributes of modern scripts to carry out cross site scripting attack and suggests preventive measures.
