Hewlett Packard Enterprise OneView is a widely used IT infrastructure management software that provides centralized control over data center hardware and systems. A critical security vulnerability identified as CVE-2025-37164 affects all versions of OneView prior to 11.00. This flaw allows an unauthenticated remote attacker to execute arbitrary code on the affected system, effectively gaining full control without needing any credentials or user interaction. The vulnerability arises from improper input validation or authentication bypass mechanisms within the OneView software, enabling remote code execution (RCE) via network access. HPE has issued patches in version 11.00 and provided hotfixes for versions 5.20 through 10.20, with additional hotfixes for virtual appliance and Synergy Composer variants. The hotfix must be reapplied after certain upgrades or reimaging operations. While no exploitation in the wild has been reported, the criticality of the flaw (CVSS 10.0) and the privileged nature of OneView in managing IT infrastructure make this vulnerability extremely dangerous. Attackers exploiting this flaw could disrupt IT operations, steal sensitive data, deploy malware, or pivot to other internal systems. The vulnerability also highlights the importance of timely patch management in enterprise environments.

For European organizations, the impact of this vulnerability is severe due to the widespread use of HPE OneView in managing enterprise IT infrastructure, including servers, storage, and networking equipment. Successful exploitation could lead to complete compromise of the IT management platform, allowing attackers to manipulate hardware configurations, disrupt services, or deploy ransomware and other malware. This could result in significant operational downtime, data breaches, and loss of business continuity. Critical sectors such as finance, healthcare, telecommunications, and government agencies that rely heavily on HPE OneView for infrastructure management are particularly at risk. The unauthenticated nature of the exploit increases the attack surface, enabling remote attackers to target exposed management interfaces without prior access. Additionally, the complexity of recovery and forensic investigation after such an attack could be substantial, increasing costs and reputational damage. The threat also raises concerns about supply chain security and the integrity of managed hardware components.

European organizations should immediately assess their HPE OneView deployments and apply the official patches released in version 11.00 or the appropriate hotfixes for versions 5.20 through 10.20. Special attention must be paid to reapplying hotfixes after upgrades from 6.60 or later to 7.00.00 and after any Synergy Composer reimaging operations. Network segmentation should be enforced to restrict access to OneView management interfaces, limiting exposure to trusted administrative networks only. Multi-factor authentication (MFA) and strong access controls should be implemented around management consoles, even though the vulnerability allows unauthenticated access, to reduce other attack vectors. Continuous monitoring and logging of OneView activity should be enhanced to detect anomalous behavior indicative of exploitation attempts. Organizations should also review their incident response plans to prepare for potential compromise scenarios involving infrastructure management platforms. Vendor advisories and threat intelligence feeds should be monitored for updates on exploit availability or active attacks. Finally, conducting penetration testing and vulnerability scanning focused on management software can help identify residual risks.
