Response Actions (7 steps)

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

  1. 1
    Identify exposure identify
    grep -r 'github.com/QuantumNous/new-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 `github.com/QuantumNous/new-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 'POST /api/stripe/webhook' /var/log/nginx/access.log | grep -E '(unusual_payload|sqli_pattern)'

    アクセスログで `POST /api/stripe/webhook` 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 upgrading immediately is not possible, operators should disable unused payment webhooks, enforce request body limits at a reverse proxy or load balancer, and ensure application and container logs have rotation and quotas.

    パッチが適用されるまでの応急処置として、If upgrading immediately is not possible, operators should disable unused payment webhooks, enforce request body limits at a reverse proxy or load balancer, and ensure application and container logs have rotation and quotas. 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 github.com/QuantumNous/new-api to 1.0.0-rc.11

    ステージング環境で 1.0.0-rc.11 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 POST /api/stripe/webhook 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。
