CVE-2025-37179 identifies multiple out-of-bounds read vulnerabilities in Hewlett Packard Enterprise's ArubaOS, specifically affecting 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 allocated buffer boundaries, classified under CWE-125 (Out-of-bounds Read). While this does not directly compromise confidentiality or integrity, it can cause the affected process to crash under specific conditions, leading to a denial-of-service (DoS) scenario. The vulnerability can be exploited remotely over the network without requiring authentication or user interaction, increasing its accessibility to attackers. However, no known exploits have been reported in the wild to date. ArubaOS is widely used in enterprise wireless and wired network infrastructure, meaning that affected devices could experience service interruptions if exploited. The CVSS v3.1 base score is 5.3, reflecting a medium severity level, with the vector indicating network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), and impact limited to availability (A:L) only. This vulnerability underscores the importance of robust input validation in network device firmware to prevent memory safety issues that can disrupt critical network services.

For European organizations, the primary impact of CVE-2025-37179 is potential denial-of-service conditions affecting network infrastructure devices running vulnerable ArubaOS versions. This can lead to temporary loss of wireless or wired network connectivity, disrupting business operations, communications, and access to critical services. While the vulnerability does not expose sensitive data or allow unauthorized changes, the availability impact can be significant in environments relying heavily on Aruba networking equipment for internal and external connectivity. Sectors such as finance, healthcare, government, and telecommunications could face operational disruptions, especially if redundancy and failover mechanisms are not robust. Additionally, attackers could leverage this vulnerability as part of a broader attack chain to degrade network reliability or distract security teams. The lack of known exploits reduces immediate risk, but the ease of exploitation without authentication means that threat actors could develop exploits rapidly once the vulnerability is public knowledge. Therefore, European enterprises should prioritize detection and mitigation to maintain network service continuity.

1. Monitor Hewlett Packard Enterprise advisories closely and apply official patches or firmware updates for ArubaOS versions 8.10.0.0 and 8.12.0.0 as soon as they become available. 2. Implement network segmentation to isolate critical ArubaOS devices from untrusted networks, reducing exposure to remote exploitation attempts. 3. Deploy intrusion detection and prevention systems (IDS/IPS) with signatures or behavioral rules to detect anomalous traffic patterns that may trigger the vulnerability. 4. Regularly audit and update network device configurations to minimize unnecessary services and restrict management access to trusted administrators only. 5. Establish robust redundancy and failover mechanisms for wireless and wired network infrastructure to mitigate potential service disruptions. 6. Conduct proactive vulnerability scanning and penetration testing focused on network infrastructure to identify and remediate similar memory safety issues. 7. Maintain comprehensive logging and monitoring of ArubaOS devices to quickly detect crashes or abnormal behavior indicative of exploitation attempts. 8. Educate network operations and security teams about this vulnerability and response procedures to ensure rapid incident handling.
