Concrete steps and command examples for SOC/SRE teams to execute in order
-
1Identify exposure identify
grep -r 'github.com/fission/fission' . | 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/fission/fission` を grep し、稼働しているサービス・バージョンを把握する。
-
5Apply temporary workaround mitigate
set networkPolicy.: enabledパッチが適用されるまでの応急処置として、set networkPolicy.: enabled を実施。回避策の副作用 (機能低下) を確認した上で。
-
6Apply patch patch
Upgrade github.com/fission/fission to 1.23.0ステージング環境で 1.23.0 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。
-
7Post-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。
