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docker pull kmmanoj/vulnerable-apis (may be outdated with respect to the current state of the repo)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