Note: This project will be discontinued after December 13th, 2021.

The vulnerable code database (Vulncode-DB) is a database for vulnerabilities and their corresponding source code if available. The database extends the NVD / CVE data sets with user-supplied information regarding patch links, vulnerable code offsets and descriptions. Particularly, the database intends to make real-world examples of vulnerable code universally accessible and useful.

The main instance is hosted on vulncode-db.com and more context is provided at vulncode-db.com/about.

• Bootstrapping problem - Vulncode-DB 's usefulness depends on having unique content. We can automatically detect some vulnerability patches via CVE/NVD metadata. We can also highlight relevant sections and annotate them in a write-up fashion. We also allow users to modify or annotate content themselves. However, this by itself is insufficient to make anyone use the platform. You need much and high-quality data first to make this useful, which a prototype like ours can't attain at this stage without extensive investment.
• Lack of community support - While there was some positive feedback there have been only a few contributors. The platform and vision seem to be inadequate to get more practical support.
• Insufficient resources - Developing the platform and for example a feature like a version control system for user moderated content similar to Wikipedia requires much engineering work for which we, as 20% contributors, are understaffed.
• Added value unknown - Even if all of the above would be solved it's still unclear whether the platform would provide sufficient value for individuals to justify a dedicated project. You can go to CVE details or Google for write-ups to learn more about a vulnerability. This is an established habit, hard to break and might already be good enough for individuals to learn more.

• This repository will be kept alive. However, we'll discontinue the https://vulncode-db.com website and API after December 13th, 2021.

• We're open to feedback, let's talk! You can reach us via https://twitter.com/evonide (rhabalov [at] gmail.com) or https://twitter.com/bluec0re.

Finally, thank you to all contributors and individuals who supported the project. We are very grateful for your support, time and feedback.

Best,

Ruslan and Timo

The setup is simplified with Docker and docker-compose in particular. Having these prerequisites installed you can setup the project using the following instructions:

# Clone the repository and its (third-party) submodules.
git clone --recursive https://github.com/google/vulncode-db.git
cd vulncode-db
# Setup configuration files, the Docker images and containers.
./setup.sh
# Initialize the application and run an empty version of it.
./docker/docker-admin.sh start

Additionally, if you intend to add some data consider running:

# Fetch and insert CWE identifiers and some recent NVD entries.
./docker/docker-admin.sh init
# Search for entries with patch links and add additional application entries for them.
./docker/docker-admin.sh crawl_patches
# Run the application.
./docker/docker-admin.sh start

The main application should then be available at http://localhost:8080.

Please also see the documentation provided in docker/README.md for more details.
