あなただけのvuls.dbを作ろう！

はじめに

Vuls は エージェントレス で動く OSS の脆弱性スキャナです。

複数 OS・ミドルウェアを横断してスキャンできますが、その裏側では

NVD／OVAL／CVE List など 多種多様な脆弱性データベース
それぞれフォーマットも更新タイミングも異なる
脆弱性DBのフェッチが面倒

という課題がありました。

そこで登場したのが vuls.db です。
従来のgo-cve-dictionary、goval-dictionary、gost などのDBを1つにまとめ、さらに VEX・CSAF など次世代フォーマット も取り込める “統合 DB” として進化しています。

vuls.dbは次のようにFetchとExtract、DBの3つの工程を経て、作成・配布されます。

このブログでは

自分専用の vuls.db を作る手順

を解説します。

あなただけのvuls.dbの作り方

早速、vuls.dbを作ってみましょう！
今回は、RedHat VEXとCVEProject CVE List V5が入ったvuls.dbを作りたいと思います。

はじめに、vuls.dbを作成するために必要なツールをインストールします。

  
# require go 1.24 or higher
$ go install github.com/MaineK00n/vuls2/cmd/vuls@nightly
$ go install github.com/MaineK00n/vuls-data-update/cmd/vuls-data-update@nightly

続いて、vulsとvuls-data-updateを利用して、vuls.dbを作っていきます。

  
$ vuls db init --dbpath ./vuls.db

2025/05/01 12:10:06 [INFO] Pull dotgit from ghcr.io/vulsio/vuls-data-db:vuls-data-extracted-redhat-vex

$ vuls-data-update dotgit pull --dir . --restore ghcr.io/vulsio/vuls-data-db:vuls-data-extracted-mitre-v5
2025/05/01 12:10:06 [INFO] Pull dotgit from ghcr.io/vulsio/vuls-data-db:vuls-data-extracted-mitre-v5

$ vuls db add --dbpath vuls.db vuls-data-extracted-mitre-v5

2025/05/01 12:34:18 INFO Put Vulnerability Data

2025/05/01 12:34:33 INFO Put Metadata

$ rm -rf vuls-data-extracted-mitre-v5

では、作成したvuls.dbからCVEを検索してみましょう。

もちろん、vulsでの脆弱性検知に作成したvuls.dbを使うこともできます。

  
$ cat config.toml
...
[vuls2]
Path = "/path/to/vuls.db"
SkipUpdate = true # 作成したDBが更新されないために
...

# future-architect/vulsをvuls0とする
$ curl -sL https://github.com/future-architect/vuls/releases/download/v0.30.0/vuls_0.30.0_linux_amd64.tar.gz | tar zxf - vuls
$ mv vuls vuls0

さて、ここでvulsio/vuls-db-templateを紹介しようと思います。
GitHub Actionsで定期的にvuls.dbを作成して、作成したvuls.dbを自身のPackagesに公開するまでを、このテンプレートリポジトリを利用することで簡単に行えます。
先程、手動で作ったvuls.dbも、vuls-db-templateを利用することによって、次のようにGNUMakefileを変更するだけで、GitHub Actionsがvuls.dbを作成してくれます。

ユースケース紹介

これまで、vulsやvuls-data-updateを使う方法、またはvuls-db-templateを利用する方法という2つのvuls.dbの作り方を紹介しました。
これから、あなただけのvuls.dbを作るべきユースケースを3つ紹介します。

1. オフィシャルで採用されていないデータソースを使いたい

次の記事によると、RedHatは、OVALに代わるフォーマットとしてCSAF、VEXを採用し、2024年末に廃止予定でした。
OVALは2024年末に廃止はされなかったものの、RHEL 10といった将来のメジャーリリース向けのデータは提供されないようです。

よって、vulsはRedHatに対するデフォルトのデータソースをOVALからVEXに変更しました。

https://github.com/vulsio/vuls-data-db/commit/45b078f8888a81b82851d61285cf1663c68c1284

フォーマットの変更により、未修正の脆弱性に紐付くパッケージが、binary packageからsource packageに変更されています。
よって、スキャナが古い場合など、スキャン対象のsource packageが収集できていない場合、オフィシャルなvuls.dbでは、未修正な脆弱性を検知できなくなります。
そこで、OVALが入ったvuls.dbを作成・利用することで、この問題を一時的に回避できます。

2. オフィシャルなvuls.dbに必要のないデータソースがある

オフィシャルで配布するvuls.dbは、ユーザがどんな対象をスキャンするかわからないため、vulsでサポートする対象のデータソースをすべて追加する予定です。
goval-dictionaryやgostでは、必要な分だけDBに追加することができました。
もし、自分たちの環境に必要なデータソースだけを含むvuls.dbが必要であれば、紹介した方法でvuls.dbを作成してください。

3. 自前で持っているデータソースをvuls.dbに追加したい

vuls.dbでは、goval-dictionaryやgostなどと異なり、ユーザ自身が持っているデータソースを追加できるように考えています。

例えば、次のようにデータを用意します。

  
  




$ tree vuls-data-extracted-test/
vuls-data-extracted-test/
├── data
│   └── 2025
│       └── TEST-2025-0001.json

そして、用意したデータをvuls.dbに追加して、TMP-2025-0001を検索してみます。
すると、検索結果に自分が用意したデータの内容が追加されていることがわかります。
