Exploitation Conditions

Exploitation requires an authenticated local session on the Dell PowerStore appliance with at least limited user privileges, confirmed by CVSS PR:L and AV:L. The attacker must be able to supply input to the vulnerable OS command execution path, most likely through the appliance's management CLI or administrative interface accessible to limited-privilege accounts. Remote unauthenticated exploitation is not possible given the local attack vector. No non-default configuration is indicated as a prerequisite - any limited-privilege local account appears sufficient. Exploitation is bounded by the requirement for prior local credential access, which limits the attacker population to insiders, compromised credential holders, or attackers who have already established a foothold in the data center management plane.

Impact

The 8.8 CVSS score reflects a structurally serious vulnerability: low complexity, low initial privileges, no user interaction required, and full C/I/A impact with scope change. However, the local attack vector (AV:L) substantially limits real-world risk compared to a network-exploitable flaw - an attacker must already hold a local authenticated session with at least limited privileges (PR:L), which rules out remote unauthenticated exploitation. No EPSS score was provided in the available intelligence, and no CISA KEV listing or public POC was identified, making exploitation status unknown rather than confirmed. The primary realistic risk scenarios are insider threat, credential compromise followed by local access, or lateral movement from within the data center management network. The scope change to root means that once exploitation succeeds, the entire appliance and its stored data are fully under attacker control, warranting prioritized patching especially in multi-tenant or shared-access storage environments.

Exploit ScenarioDerived

An attacker who has obtained a low-privilege local account on a Dell PowerStore appliance - through credential theft, insider access, or lateral movement from a compromised data center host - supplies crafted input containing shell metacharacters to a management command or configuration interface. The unsanitized input is passed to an OS-level execution function, injecting arbitrary commands that run as root. The attacker achieves full appliance control, enabling exfiltration of all stored data, disruption of storage services, or further lateral movement. No public POC has been identified at time of analysis.

AnalysisAIv1 – Sep 01, 2026

OS command injection in Dell PowerStore allows a locally authenticated user with limited privileges to execute arbitrary commands with root privileges, achieving full appliance compromise. The CVSS:3.1 vector (AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H, score 8.8) confirms low-complexity local privilege escalation with scope change to root, covering complete confidentiality, integrity, and availability impact. No public exploit or CISA KEV listing has been identified at time of analysis, but the low attack complexity and full impact triad make this a meaningful risk for environments where multiple accounts share local PowerStore access.

RemediationAI

Apply the security update documented in Dell advisory DSA-2026-330 at https://www.dell.com/support/kbdoc/en-us/000497829/dsa-2026-330-dell-powerstore-t-security-update-for-multiple-vulnerabilities. Exact patched firmware or PowerStore OS version numbers are not confirmed in the available intelligence - consult the advisory directly for the specific target release. As a compensating control prior to patching, restrict local shell and CLI access on PowerStore appliances to only essential administrative accounts, eliminating any unnecessary limited-privilege accounts that could serve as an attack foothold. Enforce role-based access control to ensure limited-privilege users cannot reach the vulnerable command execution surface, and audit audit logs for anomalous command patterns. Note that restricting local user access may impact operational workflows for teams using limited-privilege roles.

Technical ContextAI · show details

Dell PowerStore is an enterprise all-flash storage appliance platform widely deployed in data center environments. CWE-78 (Improper Neutralization of Special Elements used in an OS Command) indicates that user-supplied input is incorporated into an OS-level command execution path without adequate sanitization or escaping, enabling injection of shell metacharacters or subcommands. The CVSS scope change (S:C) reflects escalation from a limited-privilege management or shell account to root-level OS execution on the appliance's underlying operating system. The local attack vector (AV:L) indicates the vulnerable code path is accessible via the appliance's local management CLI, administrative shell, or equivalent interface available to authenticated users with limited roles.

DescriptionCVE.org

Dell PowerStore contains an OS Command Injection vulnerability. An authenticated user with limited privileges could potentially exploit this vulnerability to execute arbitrary commands with root privileges.

Executive ViewAI

Why It Matters

Dell PowerStore appliances contain a local privilege escalation vulnerability (CVE-2026-58567) that allows authenticated users with limited privileges to execute arbitrary commands as root, potentially compromising the entire storage appliance. An attacker with basic local account access could steal sensitive data or disrupt critical storage infrastructure. Organizations where multiple users share local shell access to PowerStore systems face elevated risk of insider abuse or account compromise.

Business Impact: High
Compensating Controls

No vendor-released patch identified at time of analysis. Implement interim mitigations: restrict local shell access through Dell PowerStore RBAC to administrators only; disable local login for service and non-administrative accounts; enable full audit logging of local authentication and privileged commands; segment network access to PowerStore administrative interfaces; conduct quarterly reviews to remove unnecessary local account privileges.
