Installation

Docker

Clone the repository

git clone [email protected]:dolevf/Damn-Vulnerable-GraphQL-Application.git && cd Damn-Vulnerable-GraphQL-Application

Build the Docker image

docker build -t dvga .

Create a container from the image

docker run -t -p 5000:5000 -e WEB_HOST=0.0.0.0 dvga

In your browser, navigate to http://localhost:5000

Optionally, if you need the application to bind on a specific port or interface, use the following command: docker run -e WEB_HOST=0.0.0.0 -e WEB_PORT=8080 -t -p 8080:8080 dvga

Server

Navigate to /opt

cd /opt/

Clone the repository

git clone [email protected]:dolevf/Damn-Vulnerable-GraphQL-Application.git && cd Damn-Vulnerable-GraphQL-Application

Install Requirements

pip3 install -r requirements.txt

Run application

python3 app.py

In your browser, navigate to http://localhost:5000.

Disclaimer

DVGA is highly insecure, and as such, should not be deployed on internet facing servers. By default, the application is listening on 127.0.0.1 to avoid misconfigurations.

DVGA is intentionally flawed and vulnerable, as such, it comes with no warranties. By using DVGA, you take full responsibility for using it.
