CVE-2025-37179 identifies multiple out-of-bounds read vulnerabilities in Hewlett Packard Enterprise's ArubaOS (AOS) versions 8.10.0.0 and 8.12.0.0. The root cause is insufficient validation of maximum buffer size values within a system component responsible for handling certain data buffers. This flaw allows the process to read memory beyond the intended buffer boundaries, classified under CWE-125 (Out-of-bounds Read). While this vulnerability does not permit direct data leakage or code execution, it can cause the affected process to crash under specific conditions, leading to denial-of-service (DoS) scenarios. The CVSS v3.1 score of 5.3 reflects a medium severity level, with an attack vector of network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), and no user interaction (UI:N). The impact is limited to availability (A:L) with no confidentiality (C:N) or integrity (I:N) impact. No patches were listed at the time of reporting, and no known exploits have been observed in the wild. ArubaOS is widely used in enterprise wireless and wired network infrastructure, making this vulnerability relevant for organizations relying on HPE networking equipment. The vulnerability's exploitation could disrupt network services by crashing critical processes, potentially affecting business continuity and operational stability.

For European organizations, the primary impact of CVE-2025-37179 is the potential for denial-of-service conditions on ArubaOS-managed network devices. This could lead to temporary loss of network connectivity or degraded network performance, affecting both wired and wireless communications. Critical sectors such as finance, healthcare, government, and telecommunications that rely heavily on stable network infrastructure could experience operational disruptions. Although the vulnerability does not compromise data confidentiality or integrity, service outages can indirectly impact business operations and availability of critical services. The lack of required authentication and user interaction increases the risk of remote exploitation by attackers scanning for vulnerable ArubaOS devices. However, the absence of known exploits in the wild reduces immediate threat levels. European organizations with large-scale deployments of ArubaOS should prioritize monitoring and mitigation to prevent potential service interruptions.

1. Monitor Hewlett Packard Enterprise advisories closely for official patches addressing CVE-2025-37179 and apply them promptly once available. 2. Implement network segmentation to isolate ArubaOS devices from untrusted networks, reducing exposure to remote attacks. 3. Employ intrusion detection and prevention systems (IDS/IPS) to detect anomalous traffic patterns or repeated attempts to exploit buffer handling. 4. Regularly audit and update ArubaOS firmware to the latest stable versions beyond 8.12.0.0 and 8.10.0.0 to benefit from security improvements. 5. Configure device logging and alerting to capture process crashes or unusual behavior indicative of exploitation attempts. 6. Limit network access to management interfaces of ArubaOS devices using access control lists (ACLs) and VPNs. 7. Conduct internal penetration testing and vulnerability scanning focused on network infrastructure to identify potential exposure. 8. Train network operations teams to recognize signs of denial-of-service attacks and respond swiftly to minimize downtime.
