Vulnerability in github.com/grafana/grafana (CVE-2021-41244)

Summary

Vulnerability in github.com/grafana/grafana (CVE-2021-41244). Successful exploitation can lead to full system takeover. Mitigation: upgrade to 8.2.4 or later.

Original description

The description as published by the source.

Impact

On Nov. 2, during an internal security audit, we discovered that when the fine-grained access control beta feature is enabled and there is more than one organization in the Grafana instance, Grafana 8.0 introduced a mechanism which allowed users with the Organization Admin role to list, add, remove, and update users’ roles in other organizations in which they are not an admin.

Patches

Fixed in 8.2.4

Workarounds

All installations between v8.0 and v8.2.3 that have fine-grained access control beta enabled and more than one organization should be upgraded as soon as possible. If you cannot upgrade, you should turn off the fine-grained access control using a feature flag.

Grafana Cloud instances have not been affected by the vulnerability.

Response actions

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

  1. 1
    Identify exposure identify
    grep -r 'github.com/grafana/grafana' . | 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/grafana/grafana 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 github.com/grafana/grafana to 8.2.4

    ステージング環境で 8.2.4 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。
