Ruby Advisory Database

The Ruby Advisory Database is a community effort to compile all security advisories that are relevant to Ruby libraries.

You can check your own Gemfile.locks against this database by using bundler-audit.

Support Ruby security!

Do you know about a vulnerability that isn't listed in this database? Open an issue, submit a PR, or use this form which will email the maintainers.

Directory Structure

The database is a list of directories that match the names of Ruby libraries on rubygems.org. Within each directory are one or more advisory files for the Ruby library. These advisory files are named using the advisories' CVE identifier number.

gems/:
  actionpack/:
    CVE-2014-0130.yml  CVE-2014-7818.yml  CVE-2014-7829.yml  CVE-2015-7576.yml
    CVE-2015-7581.yml  CVE-2016-0751.yml  CVE-2016-0752.yml

Format

Each advisory file contains the advisory information in YAML format:

---
gem: examplegem
cve: 2013-0156
date: 2013-05-01
url: https://github.com/rubysec/ruby-advisory-db/issues/123456
title: |
  Ruby on Rails params_parser.rb Action Pack Type Casting Parameter Parsing
  Remote Code Execution

description: |
  Ruby on Rails contains a flaw in params_parser.rb of the Action Pack.
  The issue is triggered when a type casting error occurs during the parsing
  of parameters. This may allow a remote attacker to potentially execute
  arbitrary code.

Schema

  • gem [String] (required): Name of the affected gem.
  • framework [String] (optional): Name of the framework which the affected gem belongs to.
  • platform [String] (optional): If this vulnerability is platform-specific, name of platform this vulnerability affects (e.g. jruby)
  • cve [String] (optional): Common Vulnerabilities and Exposures (CVE) ID.
  • osvdb [Integer] (optional): Open Sourced Vulnerability Database (OSVDB) ID.
  • ghsa [String] (optional): GitHub Security Advisory (GHSA) ID.
  • url [String] (required): The URL to the full advisory.
  • title [String] (required): The title of the advisory or individual vulnerability.
  • date [Date] (required): The public disclosure date of the advisory.
  • description [String] (required): One or more paragraphs describing the vulnerability.
  • cvss_v2 [Float] (optional): The CVSSv2 score for the vulnerability.
  • cvss_v3 [Float] (optional): The CVSSv3 score for the vulnerability.
  • unaffected_versions [Array<String>] (optional): The version requirements for the unaffected versions of the Ruby library.
  • patched_versions [Array<String>] (optional): The version requirements for the patched versions of the Ruby library.
  • related [Hash<Array<String>>] (optional): Sometimes an advisory references many urls and other identifiers. Supported keys: cve, ghsa, osvdb, and url

Tests

Prior to submitting a pull request, run the tests:

bundle install
bundle exec rspec

GitHub Advisory Sync

There is a script that will create initial yaml files for RubyGem advisories which are in the GitHub Security Advisory API, but are not already in this dataset. This script can be periodically run to ensure this repo has all the data that is present in the GitHub Advisory data.

The GitHub Advisory API requires a token to access it.

To run the GitHub Advisory sync, start by executing the rake task:

GH_API_TOKEN=<your GitHub API Token> bundle exec rake sync_github_advisories
  • The rake task will write yaml files for any missing advisories.
  • Those files must be further edited.
    • Fill in cvss_v3 field by following the CVE link and getting it from page
    • Fill in patched_versions field, using the comments at the bottom of the file
    • Fill in unaffected_versions, optional, if there are unaffected_versions
    • delete the GitHub data at the bottom of the yaml file
    • double check all the data, commit it, and make a PR
      • The GitHub Advisory data is structured opposite of RubySec unfortunately: GitHub identifies version range which are vulnerable; RubySec identifies version ranges which are not vulnerable. This is why some manual work to translate is needed.
