CVE-2025-37132 is an arbitrary file write vulnerability identified in Hewlett Packard Enterprise's ArubaOS (AOS) web-based management interface, affecting both AOS-10 Gateway and AOS-8 Controller/Mobility Conductor operating systems. The vulnerability exists due to improper validation of file uploads, allowing an authenticated attacker with high privileges to upload arbitrary files to the system. This capability enables the attacker to 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. The vulnerability is classified under CWE-434 (Unrestricted Upload of File with Dangerous Type). Exploitation requires authentication but no user interaction, and the attack vector is network-based, meaning the attacker can exploit it remotely once authenticated. The CVSS v3.1 base score is 7.2, indicating high severity with impacts on confidentiality, integrity, and availability. No public exploits or patches are currently available, but the vulnerability is publicly disclosed and should be addressed promptly. The vulnerability could be leveraged by malicious insiders or attackers who have obtained valid credentials to gain persistent and elevated access to critical network infrastructure devices, potentially disrupting network operations or exfiltrating sensitive data.

For European organizations, this vulnerability poses a significant risk to network infrastructure security, especially for enterprises and service providers relying on HPE ArubaOS for wireless and wired network management. Successful exploitation could lead to unauthorized command execution, enabling attackers to manipulate network configurations, intercept or redirect traffic, disrupt availability, or establish persistent footholds. This could impact confidentiality of sensitive communications, integrity of network policies, and availability of critical network services. Organizations in sectors such as finance, healthcare, telecommunications, and government are particularly vulnerable due to their reliance on secure and stable network environments. The requirement for authentication reduces the risk from external unauthenticated attackers but raises concerns about insider threats and credential compromise. The lack of patches at the time of disclosure increases the window of exposure. Additionally, the centralized nature of ArubaOS management interfaces means a single compromised device could affect multiple network segments, amplifying the impact.

European organizations should immediately implement strict access controls to limit management interface access to trusted administrators only, ideally via VPN or dedicated management networks. Multi-factor authentication (MFA) should be enforced for all accounts with access to ArubaOS management interfaces to reduce the risk of credential compromise. Network segmentation should isolate management interfaces from general user networks to minimize exposure. Continuous monitoring and logging of management interface activities should be enabled to detect anomalous file uploads or command executions. Organizations should prepare for rapid deployment of patches once HPE releases them and consider virtual patching techniques such as web application firewalls (WAFs) or intrusion prevention systems (IPS) to detect and block exploitation attempts. Regular credential audits and immediate revocation of unused or compromised accounts are critical. Additionally, security teams should conduct penetration testing and vulnerability assessments focused on ArubaOS devices to identify potential exploitation paths.
