CVE-2025-37178 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 in 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 does not directly lead to information disclosure or code execution, the out-of-bounds read can cause the affected process to crash under specific conditions, resulting in a denial-of-service (DoS) condition. The vulnerability is remotely exploitable without authentication or user interaction, increasing its risk profile. The CVSS v3.1 score is 5.3 (medium), reflecting the limited impact on confidentiality and integrity but notable availability concerns. No patches or known exploits are currently available, but the vulnerability's presence in network infrastructure software like ArubaOS could disrupt wireless network services if exploited. ArubaOS is widely used in enterprise wireless LAN controllers and access points, making this a relevant concern for organizations relying on HPE networking products.

For European organizations, the primary impact of CVE-2025-37178 is the potential disruption of network services due to process crashes causing denial-of-service conditions. ArubaOS is commonly deployed in enterprise wireless networks, including in sectors such as finance, healthcare, government, and critical infrastructure. A successful exploit could interrupt wireless connectivity, impacting business operations, communications, and access to critical applications. Although the vulnerability does not compromise data confidentiality or integrity, availability interruptions can lead to operational downtime, reduced productivity, and potential cascading effects on dependent systems. Organizations with high reliance on ArubaOS-managed wireless environments, especially those with limited redundancy or failover capabilities, are at increased risk. The lack of authentication requirements for exploitation means attackers could target exposed network interfaces remotely, emphasizing the need for network segmentation and access controls. The absence of known exploits currently reduces immediate risk but does not eliminate the threat, especially as threat actors may develop exploits over time.

1. Implement strict network segmentation to isolate ArubaOS management interfaces from untrusted networks, limiting exposure to potential attackers. 2. Employ access control lists (ACLs) and firewall rules to restrict inbound traffic to ArubaOS devices only from trusted sources. 3. Monitor ArubaOS device logs and network traffic for signs of abnormal process crashes or repeated service interruptions that could indicate exploitation attempts. 4. Prepare incident response plans to quickly address potential denial-of-service events impacting wireless infrastructure. 5. Engage with HPE support channels to obtain updates on patches or workarounds as they become available and prioritize timely deployment. 6. Consider deploying redundant wireless controllers or failover mechanisms to maintain network availability in case of service disruption. 7. Regularly audit and update ArubaOS firmware and configurations to minimize exposure to known vulnerabilities. 8. Limit exposure of ArubaOS devices to the internet or untrusted networks wherever possible to reduce attack surface.
