vulnerable-apis

vulnerable APIs inspired by https://github.com/mattvaldes/vulnerable-api

Setup

Docker

If, Out of the box

docker pull kmmanoj/vulnerable-apis (may be outdated with respect to the current state of the repo)

Else, Build the application as docker image (preferred)

docker build -t kmmanoj/vulnerable-apis .

Finally, Run the application as docker container

docker run --name vuln-api-instance --rm -it -p 5000:5000 kmmanoj/vulnerable-apis

Traditional way

Create a python virtual environment: virtualenv venv

Activate the virtual environment: source ./venv/bin/activate

Install the dependencies: pip install -r src/requirements.txt

Start the application with specific environment variables: TRANSIENT_DB=true python src/main.py

Fork the collection and the environment in Postman

Open Postman (desktop agent preferrably)

Fork the collection and environment to your own workspace by clicking the Run in Postman button below.

Or separately, fork the collection to a workspace of your choice.

And fork the environment to the same workspace where you forked the above collection.

Set the initial value and current value of the host variable to http://localhost:5000

Go back to the collections and start hacking!

Using util (if using the docker setup)

Login to the container

docker exec -it vuln-api-instance /bin/bash

Navigate to /util to use the JWT token break(or)make tool.

cd /util

Usage of JWT Token break(or)make

Usage:
	python3 brute_force_jwt_token.py make - to create a token using a leaked secret
	python3 brute_force_jwt_token.py break - to find the secret used by JWT token

NOTE: For non-containerized deployments, find the util directory in the repository itself. The required dependencies are already installed in the virtual environment.

Performance

example

$ ab -n 5000 -c 100 -T 'application/json' -p login.json http://127.0.0.1:5000/user/login
