CVE-2022-37910 is a buffer overflow vulnerability identified in the command line interface (CLI) of Hewlett Packard Enterprise's ArubaOS products, specifically affecting Aruba Mobility Conductor (formerly known as Mobility Master), Aruba Mobility Controllers, WLAN Gateways, and SD-WAN Gateways managed via Aruba Central. The vulnerability stems from improper handling of input within the CLI, leading to a buffer overflow condition (classified under CWE-120). Exploiting this flaw allows an attacker with high privileges and network access to cause a denial of service (DoS) by crashing or destabilizing the affected device. The vulnerability does not impact confidentiality or integrity but directly affects availability. The CVSS v3.1 base score is 4.4 (medium severity), with the vector indicating network attack vector (AV:N), high attack complexity (AC:H), requiring privileges (PR:H), no user interaction (UI:N), unchanged scope (S:U), and impact limited to availability (A:H). No known exploits have been reported in the wild, and no patches or fixes are currently linked in the provided data. The affected products are critical network infrastructure components used to manage wireless and SD-WAN environments, meaning disruption could impact enterprise network operations significantly. The vulnerability requires an attacker to have high-level privileges on the device and network access, which limits exploitation to insiders or attackers who have already compromised network segments or credentials. The absence of user interaction simplifies exploitation once access is obtained, but the high attack complexity and privilege requirement reduce the likelihood of widespread exploitation. Overall, this vulnerability presents a risk of service disruption in enterprise wireless and SD-WAN environments managed by Aruba products, necessitating timely mitigation to maintain network availability and stability.

For European organizations, the primary impact of CVE-2022-37910 is the potential denial of service on critical network infrastructure devices that manage wireless and SD-WAN connectivity. Disruption of Aruba Mobility Controllers, Mobility Conductor, WLAN Gateways, or SD-WAN Gateways could lead to loss of network availability, affecting business operations, communications, and access to cloud or internal resources. This is particularly impactful for sectors relying heavily on wireless connectivity and SD-WAN for distributed office environments, such as finance, manufacturing, healthcare, and public services. Given that the vulnerability requires high privileges and network access, the risk is elevated in environments where internal threat actors or lateral movement by attackers is possible. The lack of confidentiality or integrity impact reduces the risk of data breaches directly from this vulnerability, but availability loss can cause operational downtime, potential financial losses, and reputational damage. Additionally, organizations using Aruba Central for centralized management may face broader impact if multiple devices are affected simultaneously. The medium severity rating suggests that while the threat is not critical, it should be addressed promptly to avoid service interruptions, especially in high-availability or mission-critical network environments.

Restrict access to the ArubaOS CLI interfaces to trusted administrators only, using network segmentation and access control lists (ACLs) to limit exposure. Implement strong authentication and authorization controls to ensure only authorized personnel have high privilege access to affected devices. Monitor network and device logs for unusual CLI activity or signs of attempted exploitation, focusing on privilege escalation or anomalous commands. Apply any available vendor patches or firmware updates as soon as they are released by Hewlett Packard Enterprise to remediate the buffer overflow vulnerability. If patches are not yet available, consider temporary mitigations such as disabling remote CLI access where possible or using out-of-band management channels with stricter controls. Conduct regular security audits and vulnerability assessments on Aruba infrastructure to identify and remediate configuration weaknesses that could facilitate exploitation. Educate network administrators on the risks associated with this vulnerability and best practices for secure device management to reduce the risk of insider threats. Leverage Aruba Central’s monitoring capabilities to detect and respond quickly to any service disruptions or anomalies related to this vulnerability.
