Prerequisites

The following Python3 libraries are required:

  • Python3
  • Flask
  • Flask-SQLAlchemy
  • Graphene
  • Graphene-SQLAlchemy

See requirements.txt for dependencies.

Installation

Docker

  • Clone the repository

git clone git@github.com:dolevf/Damn-Vulnerable-GraphQL-Application.git && cd Damn-Vulnerable-GraphQL-Application

Alternatively, pull the image directly from Docker Hub: docker pull dolevf/dvga

  • 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 git@github.com: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.
