Goof - Snyk's vulnerable demo app

A vulnerable Node.js demo application, based on the Dreamers Lab tutorial.

Running

mongod &

git clone https://github.com/Snyk/snyk-demo-todo
npm install
npm start

This will run Goof locally, using a local mongo on the default port and listening on port 3001 (http://localhost:3001)

Heroku usage

Goof requires attaching a MongoLab service to be deployed as a Heroku app. That sets up the MONGOLAB_URI env var so everything after should just work.

CloudFoundry usage

Goof requires attaching a MongoLab service and naming it "goof-mongo" to be deployed on CloudFoundry. The code explicitly looks for credentials to that service.

Cleanup

To bulk delete the current list of TODO items from the DB run:

npm run cleanup

Exploiting the vulnerabilities

This app uses npm dependencies holding known vulnerabilities.

Here are the exploitable vulnerable packages:

• Mongoose - Buffer Memory Exposure
• st - Directory Traversal
• ms - ReDoS
• marked - XSS

The exploits directory includes a series of steps to demonstrate each one.

Fixing the issues

To find these flaws in this application (and in your own apps), run:

npm install -g snyk
snyk wizard

In this application, the default snyk wizard answers will fix all the issues. When the wizard is done, restart the application and run the exploits again to confirm they are fixed.
