CVE-2025-37134 is an authenticated command injection vulnerability identified in the CLI binary of Hewlett Packard Enterprise's ArubaOS (AOS) operating system, specifically affecting AOS-8 Controllers and Mobility Conductors. The vulnerability exists in multiple affected versions including 8.10.0.0, 8.12.0.0, 8.13.0.0, 10.4.0.0, and 10.7.0.0. An attacker with valid authentication credentials can exploit this flaw to inject arbitrary commands into the system shell executed with privileged user rights. This means the attacker can perform any action on the underlying operating system, such as modifying configurations, exfiltrating sensitive data, disrupting network services, or establishing persistent backdoors. The CVSS v3.1 score of 7.2 reflects a high severity due to network attack vector, low attack complexity, required high privileges, no user interaction, and full impact on confidentiality, integrity, and availability. Although no known exploits are currently reported in the wild, the vulnerability represents a critical risk to network infrastructure security. ArubaOS is widely deployed in enterprise and service provider wireless networking environments, making this vulnerability particularly impactful. The lack of available patches at the time of disclosure necessitates immediate risk mitigation through access restrictions and monitoring until vendor updates are released.

For European organizations, exploitation of CVE-2025-37134 could lead to severe consequences including unauthorized control over critical network infrastructure, resulting in data breaches, network outages, and potential lateral movement within corporate networks. Given ArubaOS's role in managing wireless controllers and mobility conductors, attackers could disrupt enterprise wireless connectivity, impacting business operations and productivity. Confidential information traversing these networks could be exposed or manipulated, undermining compliance with GDPR and other data protection regulations. The integrity of network configurations could be compromised, allowing attackers to create persistent access or disable security controls. Availability impacts could cause denial of service conditions affecting large user populations. Organizations in sectors such as finance, telecommunications, government, and critical infrastructure are particularly vulnerable due to their reliance on secure and stable network environments. The requirement for authenticated access somewhat limits the attack surface but does not eliminate risk, especially if credential management or insider threats are weak.

1. Apply patches and updates from Hewlett Packard Enterprise as soon as they become available to address this vulnerability directly. 2. Restrict CLI access to ArubaOS Controllers and Mobility Conductors to only trusted administrators using strong multi-factor authentication (MFA). 3. Implement strict role-based access controls (RBAC) to minimize the number of users with privileged CLI access. 4. Monitor and audit CLI access logs continuously for unusual or unauthorized command execution attempts. 5. Employ network segmentation to isolate ArubaOS management interfaces from general user networks and external access. 6. Use VPNs or secure management channels with encryption and strong authentication for remote access. 7. Conduct regular security awareness training for administrators to recognize phishing or credential compromise risks. 8. Prepare incident response plans specifically addressing network infrastructure compromise scenarios. 9. Consider deploying intrusion detection/prevention systems (IDS/IPS) tuned to detect anomalous command injection patterns or suspicious activities on ArubaOS devices.
