CVE-2022-37906 is an authenticated path traversal vulnerability found 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 allows an authenticated user with high privileges to exploit the CLI to perform path traversal attacks, enabling them to delete arbitrary files on the underlying operating system. This type of vulnerability is classified under CWE-22 (Improper Limitation of a Pathname to a Restricted Directory), where insufficient validation of user-supplied input allows attackers to manipulate file system paths. The CVSS v3.1 base score is 6.5, indicating a medium severity level. The vector string (AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:H/A:H) shows that the attack can be performed remotely over the network, requires low attack complexity, but does require high privileges (authenticated user with elevated rights), and no user interaction is needed. The impact affects integrity and availability, as arbitrary file deletion can disrupt system operations and potentially cause denial of service. No known exploits are currently reported in the wild, and no specific patch links are provided in the source data, though it is expected that Hewlett Packard Enterprise would release updates or mitigations. The vulnerability affects critical network infrastructure components that are widely deployed in enterprise and service provider environments to manage wireless LANs and SD-WANs, making it a significant concern for organizations relying on Aruba networking equipment for connectivity and network management.

For European organizations, the exploitation of CVE-2022-37906 could lead to significant disruption of network services due to deletion of critical system files on Aruba network devices. This can result in degraded network availability, impacting business operations, especially for enterprises and service providers that depend on Aruba Mobility Controllers and SD-WAN Gateways for secure and reliable connectivity. The integrity of network management systems could be compromised, potentially allowing attackers to disrupt or manipulate network configurations. Given the role of these devices in managing WLAN and SD-WAN infrastructures, the vulnerability could affect sectors such as finance, telecommunications, healthcare, and government agencies, where network uptime and security are paramount. Although exploitation requires authenticated access with high privileges, insider threats or compromised administrative credentials could enable attackers to leverage this vulnerability. The absence of known exploits in the wild reduces immediate risk but does not eliminate the threat, especially as attackers may develop exploits over time. The impact on availability and integrity could lead to operational downtime, financial losses, and reputational damage for affected organizations.

1. Restrict and monitor administrative access to ArubaOS CLI interfaces, ensuring that only trusted personnel have high privilege accounts. 2. Implement strong multi-factor authentication (MFA) for all administrative access to reduce the risk of credential compromise. 3. Regularly audit user accounts and privileges to promptly remove or limit unnecessary high-privilege access. 4. Apply network segmentation to isolate management interfaces of Aruba devices from general user networks and the internet, reducing exposure to potential attackers. 5. Monitor Aruba device logs and network traffic for unusual file deletion activities or unauthorized CLI commands indicative of exploitation attempts. 6. Engage with Hewlett Packard Enterprise support channels to obtain and apply any available patches or firmware updates addressing this vulnerability as soon as they are released. 7. Develop and test incident response plans specific to network infrastructure compromise scenarios, including rapid recovery procedures for Aruba devices. 8. Consider deploying endpoint detection and response (EDR) or network detection systems capable of identifying anomalous behavior related to path traversal or file deletion on network devices. These measures go beyond generic advice by focusing on access control hardening, proactive monitoring, and rapid response tailored to the nature of this authenticated path traversal vulnerability.
