Response Actions (7 steps)

Concrete steps and command examples for SOC/SRE teams to execute in order

  1. 1
    Identify exposure identify
    grep -r 'io.root.org.apache.activemq:activemq-client' . | grep -v node_modules

    リポジトリと本番環境の依存ファイル (package-lock.json / requirements.txt / go.sum / Gemfile.lock 等) で `io.root.org.apache.activemq:activemq-client` を grep し、稼働しているサービス・バージョンを把握する。

  2. 6
    Apply patch patch
    Upgrade io.root.org.apache.activemq:activemq-client to 5.18.3-root.io.2, 6.1.3-root.io.3, 5.18.3-root.io.3, 5.18.3-root.io.7, 6.1.3-root.io.2, 5.18.3-root.io.8, 6.1.3-root.io.4

    ステージング環境で 5.18.3-root.io.2, 6.1.3-root.io.3, 5.18.3-root.io.3, 5.18.3-root.io.7, 6.1.3-root.io.2, 5.18.3-root.io.8, 6.1.3-root.io.4 に上げて回帰テスト → 本番反映。回帰テストはアプリの主要ハッピーパスと、Step 3 で見つけた異常検知の続報チェックを含めること。

  3. 7
    Post-deployment verification verify
    Confirm patched version is live in production

    パッチ適用後、ステージングで PoC または同等の悪用パターンを再現して脆弱性が閉じたことを確認。本番では Step 3 と同じログクエリでアラート再発が無いか継続監視。
