Lab 7
Level 1 - Beginner
Session Fixation Basics Lab
Level 1 Authentication simulation: learn why applications must rotate session identifiers after login to prevent fixation attacks.
Beginner
Authentication • 20 min
Learning Objectives
This lab is a controlled simulation only. No real backend or dangerous code execution is used.
Objective 1
Review a fake login and session flow where a session already exists before authentication.
Objective 2
Identify why reusing the same session after login creates fixation risk.
Objective 3
Understand why session rotation, invalidation, and secure cookies all matter after authentication.
Challenge Area
Use the input fields below to safely simulate the vulnerable behavior.
Fixed Session Identifier
Fake Login and Session Flow
Pre-login session: session-fixed-001
Login result: authentication successful
Post-login session: session-fixed-001
Submitted token: (none yet)
Result Panel
Review the fake login and session flow, then enter the pre-login session identifier that remains active after authentication.
