Hacking Your Way Inside with Broken Authentication & Access Control
Learn how to exploit broken authentication and access control to gain unauthorized access to restricted resources in this hands-on lab.

Lab overview
Broken authentication and access control vulnerabilities are critical security issues that can lead to unauthorized access to sensitive data, manipulation of user accounts, and even complete system compromise. These vulnerabilities often arise due to improper validation of user credentials and insufficient restrictions on access to application resources.
In this lab, you will explore how to exploit broken authentication to log in as an administrator user and leverage broken access control to view the basket data of other users. This hands-on lab will provide practical insights into identifying and exploiting these vulnerabilities.
Objectives
Upon completion of this lab, you will be able to:
- Understand how broken authentication can be exploited to bypass login mechanisms.
- Exploit broken access control to access unauthorized user data.
- Recognize the severity of these vulnerabilities and the importance of securing authentication and access control mechanisms.
Who is this lab for?
This lab is designed for:
- Beginners who want to understand and exploit broken authentication and access control vulnerabilities.
- Developers looking to learn how these vulnerabilities arise and how to prevent them.
- IT Professionals and Security Enthusiasts aiming to upskill in web application security.
