git commit メッセージから潜在的なソフトウェア脆弱性を発見する

gitのコミットメッセージから潜在的なソフトウェア脆弱性を見つけます。 出力形式はJSONで、関連するコミットとそのコミットに含まれる可能性のあるソフトウェア脆弱性の修正情報が含まれます。 検索はコミットメッセージのみに対する正規表現のセットに基づいています。 CVE IDが存在する場合、それらは自動的に出力に追加されます。 入力には任意のgitリポジトリまたはGHアーカイブソースを使用できます。
sudo apt install jq)git-vuln-finderはpoetryでインストールできます。poetryがインストールされていない場合は、次のコマンドを実行してください: curl -sSL https://raw.githubusercontent.com/python-poetry/poetry/master/get-poetry.py | python。
$ poetry install
$ poetry shell
$ git-vuln-finder -h
pipを使用することもできます。その後、次のようにインポートします:

pipを使用することもできます。
pipxは、Pythonパッケージが提供するスクリプト(システム全体で利用可能)を個別のvirtualenvにインストールし、システムや互いから隔離します。
usage: git-vuln-finder [-h] [-v] [-r R] [-o O] [-s S] [-p P] [-c] [-t] [-gh GH]
Finding potential software vulnerabilities from git commit messages.
optional arguments:
-h, --help show this help message and exit
-v increase output verbosity
-r R git repository to analyse
-o O Output format: [json]
-s S State of the commit found
-p P Matching pattern to use: [vulnpatterns, cryptopatterns, cpatterns] - the pattern 'all' is used to match all the patterns at once.
-c output only a list of the CVE pattern found in commit messages (disable by default)
-t Include tags matching a specific commit
-gh GH special option for gharchive, pass a file containing a PushEvent in JSON format

git-vuln-finderには3つのデフォルトパターンが用意されており、コミットメッセージに記述された潜在的な脆弱性を見つけるために選択できます。例えば:
vulnpatterns は、Webアプリケーションや一般的なセキュリティコミットメッセージを特にターゲットとした汎用脆弱性パターンです。学術論文に基づいています。cryptopatterns は、コミットメッセージに記載された暗号化エラーに関する脆弱性パターンです。cpatterns は、C/C++系言語で見られる標準的な脆弱性パターンのセットです。$ git-vuln-finder -r ~/git/curl | jq .
