Quick Start

Try it using a single command with Docker. This setup uses an SQLite database instead of MySQL.

docker run –name dvna -p 9090:9090 -d appsecco/dvna:sqlite

Access the application at

Getting Started

Damn Vulnerable NodeJS Application can be deployed in three ways

  • For Developers, using docker-compose with auto-reload on code updates
  • For Security Testers, using the Official image from Docker Hub
  • For Advanced Users, using a fully manual setup

Development Setup

Clone this repository

git clone; cd dvna

Create a vars.env with the desired database configuration


Start the application and database using docker-compose

docker-compose up

Access the application at

The application will automatically reload on code changes, so feel free to patch and play around with the application.

Using Official Docker Image

Create a file named vars.env with the following configuration


Start a MySQL container

docker run –name dvna-mysql –env-file vars.env -d mysql:5.7

Start the application using the official image

docker run –name dvna-app –env-file vars.env –link dvna-mysql:mysql-db -p 9090:9090 appsecco/dvna

Access the application at and start testing!
