JWS Standard for JWT II
rest-jwt-advanced | Level: Easy | Total Lab Runs: 0 | Premium Lab |
A REST API is running on the target machine and uses JWT based
authentication. The implementation of JWT is very crucial for the safety
of an API. The API uses the JWT library implementation that is
vulnerable to the issue documented in CVE-2018-0114.
Objective: Retrieve the flag stored on the target server.
|/auth/local||Authenticates the user and returns JWT authentication token||POST||identifier, password|
|/users||Creates a new user||POST||username, password, email, role, provider|
|/admin||Access Strapi Admin Panel||GET||-|
- This lab is dedicated to you! No other users are on this network :)
- Once you start the lab, you will have access to a Kali GUI instance.
- Your Kali instance has an interface with IP address 192.X.Y.2. Run "ifconfig" to know the values of X and Y.
- The REST API should be running on port 1337 on the machine located at the IP address 192.X.Y.3.
- node-rsa, the Node.js RSA library is provided in the GUI instance.
- The public key parameters (n and e) are transmitted as Base64urlUInt encoded values.
- Do not attack the gateway located at IP address 192.X.Y.1

Technical Support for this Lab:
There is a reason we provide unlimited lab time: you can take as much time as you need to solve a lab. However, we realize that sometimes hints might be necessary to keep you motivated!
We currently provide technical support limited to:
- Giving hints for a lab exercise
- In rare circumstances, if you have totally given up (NO!!!) then tell you how to solve it. This will be limited to sharing the solution video or lab report
- A lab exercise fails to load or has errors in it
If you need technical support, please email email@example.com clearly mention the name and link of the lab exercise and other essential details. The more descriptive you are, the faster we can help you. We will get back to you within 24 hours or less.
