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 due to improper input validation within the command line interface, classified under CWE-77 (Improper Neutralization of Special Elements used in a Command). An attacker with valid credentials can exploit this flaw to inject arbitrary commands that the underlying operating system executes with privileged user rights. This capability enables the attacker to compromise system confidentiality by accessing sensitive data, integrity by modifying configurations or files, and availability by disrupting network services. The affected versions span multiple releases, including 8.10.0.0, 8.12.0.0, 8.13.0.0, 10.4.0.0, and 10.7.0.0, indicating a broad exposure across ArubaOS deployments. The vulnerability was published on October 14, 2025, with a CVSS v3.1 base score of 7.2, indicating high severity. The attack vector is network-based with low attack complexity but requires high privileges (authenticated access), and no user interaction is necessary. No public exploits have been reported yet, but the critical nature of ArubaOS in enterprise network infrastructure makes this vulnerability a significant concern. ArubaOS devices often serve as central controllers for wireless and wired network management, so exploitation could lead to widespread network compromise or disruption.

For European organizations, the impact of CVE-2025-37134 could be severe. ArubaOS controllers and mobility conductors are commonly deployed in enterprise, government, and critical infrastructure networks across Europe. Successful exploitation could allow attackers to gain privileged control over network infrastructure, leading to unauthorized data access, manipulation of network configurations, interception or disruption of communications, and potential lateral movement within networks. This could result in operational downtime, data breaches involving sensitive personal or corporate information, and damage to organizational reputation. Given the role of ArubaOS in managing wireless access points and network policies, the availability and integrity of network services could be compromised, affecting business continuity. The requirement for authenticated access somewhat limits the attack surface but insider threats or compromised credentials could facilitate exploitation. The absence of known exploits currently provides a window for mitigation, but the high impact necessitates urgent attention.

1. Apply patches or firmware updates from Hewlett Packard Enterprise as soon as they become available to address CVE-2025-37134. 2. Restrict CLI access to ArubaOS controllers and mobility conductors strictly to trusted administrators using network segmentation and access control lists (ACLs). 3. Enforce strong authentication mechanisms such as multi-factor authentication (MFA) for all administrative access to ArubaOS devices. 4. Regularly audit and monitor CLI command logs for unusual or unauthorized command execution attempts to detect potential exploitation early. 5. Implement network anomaly detection systems to identify suspicious traffic patterns targeting ArubaOS management interfaces. 6. Limit the number of users with privileged access and enforce the principle of least privilege. 7. Conduct regular credential hygiene practices, including password rotation and monitoring for credential compromise. 8. Consider deploying ArubaOS devices behind VPNs or secure management networks to reduce exposure. 9. Maintain an incident response plan tailored for network infrastructure compromise scenarios involving ArubaOS devices.
