Search webserver/proxy logs for unusual `POST /api/adapters/install` requests with malformed payloads or SQL meta-characters. Run `grep -r 'vps-maintenance' .` against your dependency files (package-lock.json, requirements.txt, go.sum) to find affected services.

Response Actions (7 steps)

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

1
Identify exposure identify
```
grep -r 'vps-maintenance' . | 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 `vps-maintenance` を grep し、稼働しているサービス・バージョンを把握する。
3
Hunt for indicators of compromise detect
```
grep 'POST /api/adapters/install' /var/log/nginx/access.log | grep -E '(unusual_payload|sqli_pattern)'
```
アクセスログで `POST /api/adapters/install` 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。
7
Post-deployment verification verify
```
Replay attack against POST /api/adapters/install 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。
