CVE-2025-37138 is a command injection vulnerability identified in Hewlett Packard Enterprise's ArubaOS (AOS) operating system, specifically impacting AOS-10 GW and AOS-8 Controllers/Mobility Conductor devices. The vulnerability exists within the command line interface binary, allowing an authenticated user with physical access to the hardware to inject arbitrary commands that execute with privileged system rights. This means an attacker who has both physical access to the device and valid credentials can execute arbitrary commands on the underlying operating system, potentially leading to full system compromise. The affected versions include 8.10.0.0, 8.12.0.0, 8.13.0.0, 10.4.0.0, and 10.7.0.0 of ArubaOS. The CVSS 3.1 base score is 6.2, reflecting medium severity with high impact on confidentiality, integrity, and availability, but limited by the requirement for physical access and high privileges. No public exploits or active exploitation in the wild have been reported to date. The vulnerability highlights the risk posed by insider threats or attackers who gain physical access to network infrastructure devices. ArubaOS controllers are widely used in enterprise and service provider networks for wireless and mobility management, making this vulnerability relevant for organizations relying on HPE Aruba infrastructure. The lack of publicly available patches at the time of disclosure necessitates immediate compensating controls to mitigate risk.

For European organizations, this vulnerability could lead to unauthorized command execution on critical network infrastructure devices, potentially resulting in data breaches, network disruption, or persistent unauthorized access. Since ArubaOS controllers often manage wireless and mobility services, exploitation could disrupt enterprise connectivity, degrade service availability, and compromise sensitive data traversing these devices. The requirement for physical access limits remote exploitation but raises concerns about insider threats or attackers gaining physical entry to data centers or network closets. Organizations in sectors with high physical security risks or those with distributed infrastructure are particularly vulnerable. The impact on confidentiality, integrity, and availability is high if exploited, as attackers can execute arbitrary commands with privileged access. This could facilitate lateral movement, data exfiltration, or sabotage of network operations. The medium CVSS score reflects the balance between high impact and exploitation constraints. European enterprises must consider the risk of physical security breaches combined with this vulnerability to protect their network infrastructure.

1. Enforce strict physical security controls to prevent unauthorized access to ArubaOS controllers, including locked server rooms and surveillance. 2. Limit privileged user accounts and enforce strong authentication mechanisms to reduce the risk of credential misuse. 3. Monitor command line interface logs and system activity for unusual or unauthorized commands indicative of exploitation attempts. 4. Apply ArubaOS patches or firmware updates as soon as they become available from HPE to remediate the vulnerability. 5. Implement network segmentation to isolate ArubaOS controllers from less trusted network segments, reducing attack surface. 6. Conduct regular security audits and penetration tests focusing on physical security and insider threat scenarios. 7. Educate staff on the risks of physical access and the importance of safeguarding credentials. 8. Consider deploying additional endpoint protection or host-based intrusion detection on controllers if supported. These steps go beyond generic advice by focusing on the unique requirement of physical access and privileged authentication for exploitation.
