Testing for stored cross-site scripting // Evaluating Input Validation Checks

Stored cross-site scripting occurs when malicious JavaScript is injected into an input field, parameter, or header and, after returning from the web server, is executed within the browser and becomes a permanent part of the page. Stored XSS occurs when the malicious JavaScript is stored in the database and is used later to populate the display of a web page. Penetration testers need to test all client values sent to the web server to determine whether XSS is possible.
