Dellは、PowerFlex Managerに存在する複数の脆弱性を修正した。最も深刻なCVE-2026-56688はCVSSスコア9.1で、リモートからroot権限で任意のOSコマンドを実行される可能性がある。現時点で悪用や概念実証コードは確認されていない。 CVE-2026-56688は、OS Repository処理におけるOSコマンドインジェクションで、入力値の不適切な処理により細工されたデータがシステムコマンドへ渡される。これにより、高い権限を持つリモート利用者がroot権限で任意のコマンドを実行し、アプライアンス全体を制御できる可能性がある。Dellはこのほか、CVE-2026-35065（CVSS 8.8）やCVE-2026-32804（CVSS 8.1）を含む10件以上の脆弱性も同時に修正した。これらは認証、アクセス制御、SQL処理などに影響する。影響を受けるのはPowerFlex Software 5.1.0.1未満および4.5.5.2未満で、修正版は5.1.0.1以降と4.5.5.2以降としている。DellはRCMリリース経由で更新を提供しており、更新までの間は管理インターフェースへのネットワークアクセスを制限し、コンソールへのアクセスを信頼できる管理者のみに限定するよう推奨している。 https://securityonline.info/dell-powerflex-cve-2026-56688-rce/

🚨 CRITICAL - OS command injection in PowerFlex Manager OS Repository processing (CVE-2026-56688) Dell PowerFlex Manager contains an OS command injection flaw in the OS Repository processing component, allowing attacker-controlled input to reach system command execution paths. The root cause is improper input validation/neutralization of OS command metacharacters, enabling command injection. Exploitation is possible remotely by a high-privileged attacker who can trigger OS Repository processing with crafted parameters or repository content. Successful exploitation results in arbitrary command execution as root, leading to full appliance compromise and enabling lateral movement into managed infrastructure. 👉 Affected: Dell PowerFlex Manager < 5.1.0.1 | Upgrade to 5.1.0.1
Post summary
The post discloses a critical OS command injection in Dell PowerFlex Manager and recommends upgrading to version 5.1.0.1 to resolve the issue.
