As modern software complexity increases, open-source dependencies are increasingly relied upon to efficiently incorporate functionality into these systems. Even if the software is securely designed, vulnerabilities in these third-party dependencies can lead to security breaches. VulDoctor is a web application utilizing machine learning and AI that allows users to dynamically track security vulnerabilities in their code repositories and receive updates on the newest vulnerabilities in the software component.

A sample of the application can be found here. However, all functionality may not be present.

Note: This software is primarily experimental, and hence requires some setup.

1. Install NVM curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.35.3/install.sh | bash
2. Install Node nvm install node
3. Run npm install in root directory
4. Run npm install in ./server
5. Copy .env into the root directory (see example of .env file below)
6. Add "proxy": "http://localhost:5000" to the end of package.json in the root directory.
7. Run npm start in one terminal to start the server.
8. Run npm run start-client in another terminal to start the client.

The .env file should be placed in the root directory. It contains the private keys to the services used. An example is displayed below, with obfuscation of keys, to show how the keys are referred to in the source code. Ripgrep may prove to be useful in the reverse engineering process. New accounts for each service should be made by the new maintainer.
