Response Actions (7 steps)

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

  1. 1
    Identify exposure identify
    grep -r 'nl.nl-portal:documenten-api' . | 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 `nl.nl-portal:documenten-api` を grep し、稼働しているサービス・バージョンを把握する。

  2. 3
    Hunt for indicators of compromise detect
    grep 'GET /api/documentapi/{documentapi}/document/{documentId}/content' /var/log/nginx/access.log | grep -E '(unusual_payload|sqli_pattern)'

    アクセスログで `GET /api/documentapi/{documentapi}/document/{documentId}/content` への異常なリクエスト (不正な認証ヘッダ・SQLメタ文字)を過去 30〜90日分捜索。WAF/SIEM があれば該当パスのアラート発火履歴を確認。

  3. 5
    Apply temporary workaround mitigate
    If you cannot upgrade immediately, block the path `GET /api/documentapi/*/document/*/content` and the `getDocumentContent` GraphQL query at your gateway or reverse proxy, and remove any client code that calls them.

    パッチが適用されるまでの応急処置として、If you cannot upgrade immediately, block the path `GET /api/documentapi/*/document/*/content` and the `getDocumentContent` GraphQL query at your gateway or reverse proxy, and remove any client code that calls them. を実施。回避策の副作用 (機能低下) を確認した上で。

  4. 6
    Apply patch patch
    Upgrade nl.nl-portal:documenten-api to 3.0.1

    ステージング環境で 3.0.1 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。

  5. 7
    Post-deployment verification verify
    Replay attack against GET /api/documentapi/{documentapi}/document/{documentId}/content on staging to confirm patch closes the vector

    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。
