CVE-2025-37132 is an arbitrary file write vulnerability found in Hewlett Packard Enterprise's ArubaOS (AOS) versions 8.10.0.0, 8.12.0.0, 8.13.0.0, 10.4.0.0, and 10.7.0.0. The flaw exists within the web-based management interface of both the AOS-10 Gateway and AOS-8 Controller/Mobility Conductor operating systems. An attacker with authenticated access and high privileges can exploit this vulnerability to upload arbitrary files to the system. This capability enables execution of arbitrary commands on the underlying operating system, effectively allowing full control over the affected device. The vulnerability does not require user interaction beyond authentication, and the attack vector is network-based, making remote exploitation feasible. The CVSS v3.1 score of 7.2 indicates a high severity, with the vector string showing network attack vector, low attack complexity, high privileges required, no user interaction, and high impact on confidentiality, integrity, and availability. Although no known exploits have been reported in the wild, the vulnerability poses a critical risk to network infrastructure devices that manage wireless and mobility services. ArubaOS devices are widely deployed in enterprise and service provider environments, making this vulnerability particularly concerning for organizations relying on these systems for secure network management. The lack of available patches at the time of disclosure increases the urgency for mitigation through access controls and monitoring.

The exploitation of CVE-2025-37132 can have severe consequences for European organizations. Successful attacks can lead to full compromise of ArubaOS devices, allowing attackers to execute arbitrary commands, potentially leading to data breaches, disruption of network services, and lateral movement within corporate networks. Given ArubaOS's role in managing wireless networks and mobility controllers, attackers could intercept or manipulate network traffic, degrade network availability, or pivot to other critical systems. Confidentiality is at high risk due to potential data exfiltration, integrity is compromised by unauthorized command execution, and availability can be disrupted by malicious payloads or system instability. For sectors such as finance, healthcare, government, and critical infrastructure in Europe, this vulnerability could undermine operational continuity and regulatory compliance. The requirement for high privilege authentication limits exposure but does not eliminate risk, especially if credential theft or insider threats are present. The absence of known exploits currently provides a window for proactive defense, but the high impact necessitates urgent attention.

To mitigate CVE-2025-37132, European organizations should implement the following specific measures: 1) Immediately restrict access to the ArubaOS web management interface to trusted administrative personnel and networks using network segmentation and firewall rules. 2) Enforce strong multi-factor authentication (MFA) for all administrative accounts to reduce the risk of credential compromise. 3) Monitor ArubaOS device logs and network traffic for unusual file uploads, command executions, or other suspicious activities indicative of exploitation attempts. 4) Apply vendor patches or updates as soon as they become available; if patches are not yet released, consider temporary compensating controls such as disabling the web management interface or using out-of-band management channels. 5) Conduct regular audits of administrative accounts and permissions to ensure least privilege principles are enforced. 6) Employ intrusion detection/prevention systems (IDS/IPS) tuned to detect exploitation patterns related to arbitrary file writes or command execution on ArubaOS devices. 7) Educate network administrators about the vulnerability and signs of compromise to enhance incident response readiness.
