A severe security flaw lurking within HPE OneView Software has sent a clear warning signal across the cybersecurity landscape. This critical vulnerability, capable of allowing attackers to execute arbitrary code remotely and without any authentication, demands immediate attention from IT professionals and security teams managing HPE infrastructure. The implications of such a vulnerability are profound, potentially leading to complete system compromise, data breaches, and significant operational disruption.

Understanding the Critical Threat: CVE-2025-37164

The vulnerability, officially tracked as CVE-2025-37164, has been assigned the maximum CVSS severity score of 10.0. This score, indicative of “critical risk,” signifies that the flaw is easily exploitable, requires no specialized privileges, and can lead to a complete loss of confidentiality, integrity, and availability of the affected system. For HPE OneView users, this means an unauthenticated attacker could potentially gain full control over their converged infrastructure management environment.

HPE OneView is a sophisticated infrastructure management solution designed to simplify lifecycle operations for servers, storage, and networking. Its comprehensive capabilities make it a central point of control, and as such, a high-value target for malicious actors. A remote code execution (RCE) vulnerability in such a critical system is a gateway to the entire managed environment.

• CVE ID: CVE-2025-37164
• Product: HPE OneView Software
• Vulnerability Type: Remote Code Execution (RCE)
• Severity: CVSS Score 10.0 (Critical)

The Mechanism of Attack: Remote Code Execution Unveiled

Remote Code Execution (RCE) vulnerabilities are among the most dangerous types of security flaws. They grant attackers the ability to run their own malicious code on a target system from a remote location. In the context of HPE OneView, this capability could allow an attacker to:

• Install backdoors or malware.
• Steal sensitive configuration data, credentials, and intellectual property.
• Manipulate or disrupt critical infrastructure operations managed by OneView.
• Pivot to other systems connected to the HPE OneView environment.
• Establish a persistent presence within the network for future attacks.

The “without authentication” aspect of this vulnerability significantly lowers the bar for exploitation. An attacker does not need legitimate credentials or prior access to the system, making it a particularly attractive target for broad-scale attacks and opportunistic exploitation.

Remediation Actions: Securing Your HPE OneView Environment

Given the critical nature of CVE-2025-37164, immediate action is paramount for all HPE OneView users. Organizations must prioritize applying the necessary security updates and implementing best practices to mitigate this severe risk.

• Apply Patches Immediately: HPE will release or has released security patches addressing CVE-2025-37164. Monitor HPE’s official security advisories and promptly apply all recommended updates to your HPE OneView deployments. This is the most crucial step in remediation.
• Isolate HPE OneView: Where possible, restrict network access to the HPE OneView appliance. Ensure it is only accessible from trusted administrative networks or specific hosts, reducing its exposure to potential external threats.
• Implement Network Segmentation: Segment your network to limit the blast radius of a potential compromise. If HPE OneView were to be compromised, proper segmentation would prevent an attacker from easily moving to other critical systems.
• Regular Security Audits: Conduct frequent security audits and vulnerability scans of your HPE OneView installations and the surrounding infrastructure to identify and address potential weaknesses proactively.
• Monitor Logs for Anomalies: Enhance logging and implement robust monitoring of HPE OneView activity. Look for unusual access patterns, unauthorized configuration changes, or any indicators of compromise related to this specific vulnerability.
• Review Access Controls: Even though this vulnerability does not require authentication, maintaining strict access controls for legitimate users helps contain potential internal threats or post-exploitation activities.
