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-2016-10555.
The server uses RS256 algorithm as the default signing algorithm to generate the tokens.
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.
- The public key used to verify the JWT token generated by the target server is provided in the GUI instance in the root directory.
- PyJWT, the library used to work with JWT Tokens is provided in the GUI instance.
- Do not attack the gateway located at IP address 192.X.Y.1
You can find everything you need for the challenge on the token issuer's website.
All relevant information to solve this lab is available on the CVE website.
The following activities are strictly prohibited on this website unless otherwise explicitly stated as allowed in the mission statement:
- Using automated scanners
- Using brute force attacks
- Denial of Service attacks
- Attacking other student machines in challenges where you might achieve a shell on the vulnerable system
- Attacking the lab infrastructure
Users violating the above will be either temporarily or permanently banned from the website.
If you are unsure about an activity, then please contact support to confirm that it is allowed on our website.
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 firstname.lastname@example.org 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.
