An cli based jwt testing lab to learn about how JWT token works for Authorization and session handling

Installation:

git clone https://github.com/sanjai-AK47/JWT.git
cd JWT
npm install express
npm install jsonwebtoken

How to do attack for previlage escalation:

Server.js:

Run the server.js or and server1.js for basic jwt token manipulation and escalation attack with using jwt.io

cd JWT
node server.js or server1.js

Now make a curl request with curl as user and make previlage escalation from user to admin

curl -X POST -H "Content-Type: application/json" -d '{"username":"user","password":"user"}' http://localhost:8080/login

Now you get the authentication toke make a request to dashboard

curl -H "Authorization: Bearer {YOUR JWT TOKEN}" http://localhost:8080/dashboard

You can see that you have logined as normal user in dashboard

Exploitation and solution:

Now its time to think like a hacker and made previlage escalation with using tools hashat and jwt_tool to exploit this previlage escation attack and the solution are not mentioned here because try for this attack and do something to exploit this. If anyone found the exploitation or to discuss about the exploitation you can go to discussion side and discuss with others

Information

The both server.js and server1.js has different exploitation so do both and analyse it
