Lab Description

In this hands-on lab, you will dive deep into Cross-Site Scripting (XSS) vulnerabilities, one of the most common and dangerous web application security issues. Utilizing the Damn Vulnerable Web Application (DVWA) and Mutillidae, intentionally insecure platforms designed for learning, you will simulate real-world attack scenarios to understand how XSS can be used to execute malicious scripts in user browsers.

You will practice injecting JavaScript payloads through various user input fields, revealing how insufficient input validation and sanitization can compromise session integrity and user data. You’ll explore both reflected and stored XSS attacks, examine how attackers bypass common filters, and learn how to defend against these threats using best practices in web development and security testing.

By the end of this lab, you will have a clear understanding of XSS mechanisms, the risks they pose, and how to implement effective countermeasures to strengthen your web application’s defense posture.
