A Brief Study on Defining Templates to Avoid XSS Vulnerabilities Using Auto Escape Templates for Web Applications

Abstract: Cross-site scripting (XSS) is a type of computer security vulnerabilities typically found in Web applications. XSS enables attackers to inject client-side script into web pages viewed by other users. A cross-site scripting vulnerability may be used by attackers to bypass access controls such as the same origin policy (refer Fig:1). Cross-site scripting carried out on websites accounted for roughly 84% of all security vulnerabilities documented by Symantecas of 2007 [1]. Their effect may range from a petty nuisance to a significant security risk, depending on the sensitivity of the data handled by the vulnerable site and the nature of any security mitigation implemented by the site's owner
