Method Detail

encodeXSS

public static String encodeXSS(String text)

This helper method can be used to help prevent Cross Site Scripting vulnerabilities. Any Servlet or JSP which sends user input (eg. query parameters in HTTP requests) to be rendered into a user's browser needs to use this method to encode the user input. This ensures that any HTML in their input (either malicious or otherwise) is not executed by the browser. This is achieved by converting characters to their HTML escaped form. For example, '&' is converted to '&'.

A full description of Cross Site Scripting (XSS) vulnerabilities can be found at http://www.cert.org/tech_tips/malicious_code_mitigation.html.

Parameters:

text - This is the dynamic text which is going to be sent as html (eg. URL)

Returns:

encoded text
