Challenge
Understanding Session Management Vulnerabilities in Java
In this challenge, you will learn about Java deserialization vulnerabilities in web applications. You'll review vulnerable code snippets and understand how attackers can exploit the standard ObjectInputStream to execute malicious code on a server.
-
Challenge
Understanding Cookie Security and Safe Deserialization Approaches
In this challenge, you'll learn about cookie security attributes and their importance in preventing web attacks. You'll explore how the HttpOnly, Secure, and SameSite attributes help protect against XSS, network sniffing, and CSRF attacks, respectively.

Challenge
Implementing Secure Deserialization
In this challenge, you will implement secure deserialization using ValidatingObjectInputStream. You'll modify vulnerable code to define a whitelist of trusted classes that can be safely deserialized, preventing potential remote code execution attacks.
