CVE-2025-37128 is a vulnerability identified in the web API of Hewlett Packard Enterprise's (HPE) Aruba Networking EdgeConnect SD-WAN Gateway, specifically affecting versions 9.4.0.0 and 9.5.0.0. This vulnerability allows an authenticated remote attacker to terminate arbitrary running processes on the affected device. The root cause relates to improper control over process termination commands exposed via the web API, categorized under CWE-250 (Execution with Unnecessary Privileges). Exploiting this flaw requires the attacker to have valid authentication credentials and involves user interaction, but no elevated privileges beyond that are necessary. The vulnerability's impact is primarily on availability, as terminating critical processes can disrupt system operations and potentially lead to an unstable system state or denial of service. The CVSS v3.1 base score is 6.8, indicating a medium severity level, with the vector highlighting network attack vector (AV:N), low attack complexity (AC:L), privileges required (PR:L), user interaction required (UI:R), scope changed (S:C), no confidentiality or integrity impact (C:N/I:N), and high impact on availability (A:H). No known exploits are currently reported in the wild, and no patches have been linked yet. This vulnerability is significant for organizations relying on HPE Aruba EdgeConnect SD-WAN Gateways for their network infrastructure, as it could be leveraged to disrupt critical network services remotely by authenticated users, potentially affecting business continuity and network reliability.

For European organizations, the impact of CVE-2025-37128 can be substantial, especially for enterprises and service providers utilizing HPE Aruba EdgeConnect SD-WAN solutions to manage wide area networks and ensure secure, reliable connectivity. Disruption caused by arbitrary process termination could lead to network outages, degraded performance, or unstable gateway behavior, affecting critical business operations and potentially causing financial losses or reputational damage. Given the reliance on SD-WAN for digital transformation and remote work enablement, availability issues could hinder productivity and service delivery. Additionally, the requirement for authentication limits exploitation to insiders or attackers who have compromised credentials, but this does not eliminate risk, as credential theft or misuse is common. The scope change in the CVSS vector indicates that the vulnerability can affect components beyond the initially targeted process, potentially amplifying the disruption. European organizations in sectors such as finance, telecommunications, healthcare, and government, where network uptime and security are paramount, may face increased operational risks if this vulnerability is exploited.

To mitigate CVE-2025-37128 effectively, European organizations should: 1) Immediately audit and restrict access to the HPE Aruba EdgeConnect SD-WAN Gateway web API, enforcing strict authentication and authorization controls to limit who can interact with process management functions. 2) Implement multi-factor authentication (MFA) for all users accessing the management interfaces to reduce the risk of credential compromise. 3) Monitor logs and network traffic for unusual API calls or process termination requests that could indicate attempted exploitation. 4) Segment management networks to isolate SD-WAN gateways from general user networks, minimizing exposure. 5) Engage with HPE support channels to obtain official patches or workarounds as soon as they become available and prioritize timely deployment. 6) Conduct regular vulnerability assessments and penetration testing focused on SD-WAN infrastructure to identify and remediate similar issues proactively. 7) Educate administrators and users about phishing and credential security to reduce the risk of authentication compromise. These steps go beyond generic advice by focusing on access control hardening, proactive monitoring, and network segmentation tailored to the specific nature of this vulnerability.
