Vulnerability in helm.sh/helm/v3 (CVE-2020-15184)

Summary

Vulnerability in helm.sh/helm/v3 (CVE-2020-15184). Risk of unauthorized operations or information disclosure. Exploitable via alias. Mitigation: upgrade to 3.3.2 or later.

Original description

The description as published by the source.

In Helm before versions 2.16.11 and 3.3.2 there is a bug in which the alias field on a Chart.yaml is not properly sanitized. This could lead to the injection of unwanted information into a chart. This issue has been patched in Helm 3.3.2 and 2.16.11. A possible workaround is to manually review the dependencies field of any untrusted chart, verifying that the alias field is either not used, or (if used) does not contain newlines or path characters.

Response actions

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

  1. 1
    Identify exposure identify 
    grep -r 'helm.sh/helm/v3' . | 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 helm.sh/helm/v3 を grep し、稼働しているサービス・バージョンを把握する。

  2. 2
    Apply patch patch 
    Upgrade helm.sh/helm/v3 to 3.3.2

    ステージング環境で 3.3.2 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を含めること。

  3. 3
    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。本番ではアクセスログ・WAF でアラート再発が無いか継続監視。
