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 'PUT /api/user/self' /var/log/nginx/access.log | grep -E '(unusual_payload|sqli_pattern)'

    アクセスログで `PUT /api/user/self` 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 temporarily restrict or rate-limit PUT /api/user/self and avoid allowing frequent user setting updates while Redis-backed quota cache is enabled.

    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 temporarily restrict or rate-limit PUT /api/user/self and avoid allowing frequent user setting updates while Redis-backed quota cache is enabled. 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.16

    ステージング環境で 1.0.0-rc.16 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 PUT /api/user/self 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。
