  • Hunt for exploitation attempts and persistence artifacts
  • Increase monitoring for publicly documented tradecraft

Recommended action window: Immediate (within 24h)

NVD description

Hardcoded credentials in the Basic Authentication setup tool (bin/solr auth enable) in Apache Solr versions 9.4.0 through 9.10.1 and 10.0.0 allows a remote attacker to gain full administrative access to the cluster via publicly known default credentials installed silently alongside the user-specified account. As an immediate workaround without upgrading, delete the template users (superadmin, admin, search, index) from security.json or change their passwords. The future, not yet released, versions 9.11.0 and 10.1.0 will not be vulnerable, and it will be enough to upgrade to solve the issue. Not affected: * Clusters where bin/solr auth enable was not used to bootstrap BasicAuth * Clusters where template users have been assigned strong passwords after bootstrap

    Patch

    Apache Solrの認証設定ツールに、誰でも管理者権限を取得できる危険な脆弱性が見つかった。基本認証を有効化する際に開発者が気付かないまま既知の管理アカウントが作成されるため、公開環境ではクラスタ全体を乗っ取られる恐れがある。 CVE-2026-44825はApache Solr 9.4.0~9.10.1および10.0.0に影響する脆弱性だ。問題はBasic Authentication設定ツール「bin/solr auth enable」にあり、利用者が指定したアカウントとは別に、既知の認証情報を持つテンプレートユーザーが自動的に作成される。 その結果、攻撃者は公開されているデフォルト認証情報を利用してクラスタへログインし、管理者権限を取得できる可能性がある。影響を受けるのは、このコマンドラインツールを使用して認証設定を行った環境に限られ、手動でアカウントを作成した環境は対象外とされる。 現時点では修正版の9.11.0および10.1.0は未公開のため、Apacheはsecurity.json内のsuperadmin、admin、search、indexといったテンプレートユーザーを削除するか、強力なパスワードへ変更するよう推奨している。 https://securityonline.info/apache-solr-default-credentials-cve-2026-44825/

    Post summary

    Apache Solr's Basic Authentication enable tool creates a template user with default credentials, enabling attackers to gain admin rights (CVE‑2026‑44825). Apache advises deleting those users or changing passwords and will release patched versions in the near future.
