Apprentice

In the Apprentice level of Cross-Site Scripting (XSS) labs, you'll dive deeper into the different types of XSS vulnerabilities that can be exploited in web applications. These labs focus on various attack vectors, including reflected, stored, and DOM-based XSS.

You will learn how unfiltered or unsanitized user input can be manipulated to inject malicious JavaScript into web pages. This can lead to unauthorized actions being performed in the victim's browser, such as alerting sensitive information, hijacking sessions, or redirecting users to malicious sites. Each lab provides hands-on experience in identifying and exploiting these vulnerabilities in real-world scenarios.

Throughout this level, you'll experiment with different contexts in which XSS can occur, such as:

• Reflected XSS: Malicious input is reflected off the web server into the page, often through user-controlled search fields or URLs.

• Stored XSS: Malicious input is stored in the application's database and later executed when viewed by other users.

• DOM-based XSS: Vulnerabilities that occur on the client-side, where JavaScript running in the browser allows attackers to inject malicious scripts into the page.

By completing these labs, you will gain a solid understanding of how XSS attacks work and how they can be exploited in different contexts.
