• Horizontal Access Control Issues
• Vertical Access Control Issues
• Mass Assignment
• Cross-Site Scripting
• NoSQL Injection
• Server Side Request Forgery
• JSON Web Token (JWT) Secret Key Brute Force
• Information Disclosure
• Hidden API Functionality Exposure
• Cross-Origin Resource Sharing Misonfiguration
• JSON Hijacking
• SQL Injection
• XML External Entity Injection (XXE)
• Command Injection
• XPATH Injection
• XML-RPC User Enumeration
• Open Redirect
• Path Traversal
• Unsafe Deserialization
• Sensitive Data Exposure
• GraphQL Access Control Issues
• GraphQL Introspection Enabled
• GraphQL Arbitrary File Write
• GraphQL Batching Brute Force
• Client Side Template Injection

Set Up Instructions

Manual (Preferred Method)

Node and NPM is needed to run dvws-node

Tested on:

• node v16.19.0
• npm 8.19.3

Set up a mongoDB environment to listen on port 27017. Docker can be used to quickly set this up.

docker run -d -p 27017-27019:27017-27019 --name dvws-mongo mongo:4.0.4

Create a MySQL database which listens of port 3306 Docker can be used as follows

docker run -p 3306:3306 --name dvws-mysql -e MYSQL_ROOT_PASSWORD=mysecretpassword -e MYSQL_DATABASE=dvws_sqldb -d mysql:8

Git clone the DVWS Repository

git clone https://github.com/snoopysecurity/dvws-node.git

Change directory to DVWS

cd dvws-node

npm install all dependencies (build from source is needed for libxmljs, you might also need install libxml depending on your OS: sudo apt-get install -y libxml2 libxml2-dev)

npm install --build-from-source

Run the startup script which create some test data

node startup_script.js

To start the application/API, run (sudo privileges is needed to bind to ports)

sudo npm start

Within your /etc/hosts file, ensure localhost resolves to dvws.local. This ensures URLs from swagger is resolved correctly (optional)

127.0.0.1    dvws.local

Docker Compose

If you have docker compose installed on your system, all you need to execute is :

Clone DVWS

git clone https://github.com/snoopysecurity/dvws-node.git

Change directory to dvws-node

cd dvws-node

Start Docker

`docker-compose up`

This will start the dvws service with the backend MySQL database and the NoSQL database.

If the DVWS web service doesn't start because of delayed MongoDB or MySQL setup, then increase the value of environment variable : WAIT_HOSTS_TIMEOUT
