📌 サードパーティの依存コード使用時

他のソフトウェアに埋め込まれた場合、不正アップロードを介して既存インフラ全体の妥当性が破壊されるリスク。

Recommended action

影響を受けたソフトウェアのバージョンを即座に更新し、監視システムでの異常な動作の確認と制限を行うことを推奨します。

Response actions

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

1
Identify exposure identify
```
grep -r 'path-traversal' . | 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 path-traversal を grep し、稼働しているサービス・バージョンを把握する。
4
Consider incident declaration escalate
```
Notify SOC / on-call
```
CISA KEV登録済 = 実環境で悪用が観測されている。Step 3 で兆候があればインシデント対応宣言、無くてもパッチ適用までWAF強化を最優先で。
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。
