CVE-2022-37905 is a vulnerability identified in Hewlett Packard Enterprise's ArubaOS, specifically affecting the Aruba Mobility Conductor (formerly known as Mobility Master), Aruba Mobility Controllers, WLAN Gateways, and SD-WAN Gateways managed via Aruba Central. These devices are critical components in enterprise network infrastructure, providing wireless LAN and SD-WAN management capabilities. The vulnerability allows an attacker to execute arbitrary code during the boot sequence of the affected 7xxx series controllers. This early-stage code execution is particularly severe because it occurs before the operating system fully initializes, enabling permanent modification of the underlying OS. Such a compromise could allow attackers to implant persistent backdoors or malicious firmware modifications that survive reboots and standard remediation efforts. The CVSS v3.1 base score is 6.6, indicating a medium severity level. The vector string (AV:N/AC:H/PR:H/UI:N/S:U/C:H/I:H/A:H) reveals that the attack requires network access, high attack complexity, and high privileges, but no user interaction. The vulnerability impacts confidentiality, integrity, and availability to a high degree, given the potential for full OS compromise. No known exploits are currently reported in the wild, and no patches or mitigations are explicitly linked in the provided data. The CWE-1236 classification relates to improper handling of boot or initialization code, which aligns with the vulnerability's nature. Overall, this vulnerability poses a significant risk to the integrity and trustworthiness of Aruba network devices, which are widely deployed in enterprise environments globally.

For European organizations, the impact of CVE-2022-37905 could be substantial. Aruba network devices are commonly used in enterprise and governmental networks across Europe for wireless and SD-WAN infrastructure. Successful exploitation could lead to persistent compromise of critical network infrastructure, enabling attackers to intercept, manipulate, or disrupt network traffic. This could result in data breaches affecting sensitive corporate or personal data, disruption of business operations, and potential lateral movement within networks. Given the permanent nature of the modification, remediation would require device replacement or complete firmware reinstallation, causing operational downtime and increased costs. Additionally, compromised network infrastructure could undermine trust in secure communications and expose organizations to regulatory penalties under GDPR if personal data confidentiality is breached. The requirement for high privileges and network access suggests that attackers would likely need to have already penetrated internal networks or compromised administrative credentials, emphasizing the importance of internal security controls. However, the high impact on confidentiality, integrity, and availability makes this vulnerability a critical concern for organizations relying on Aruba devices for their network backbone.

1. Immediate inventory and identification of all Aruba Mobility Conductors, Mobility Controllers, WLAN Gateways, and SD-WAN Gateways managed by Aruba Central within the organization. 2. Engage with Hewlett Packard Enterprise support channels to obtain official patches or firmware updates addressing CVE-2022-37905, as none are linked in the provided data. 3. If patches are unavailable, implement strict network segmentation to isolate affected devices from untrusted networks and limit administrative access to trusted personnel only. 4. Enforce multi-factor authentication (MFA) and strong credential management for all administrative accounts managing Aruba devices to reduce the risk of privilege escalation. 5. Monitor network traffic and device logs for unusual boot sequences or unauthorized configuration changes that may indicate exploitation attempts. 6. Develop and test incident response plans specifically for network infrastructure compromise, including procedures for device reimaging or replacement. 7. Consider deploying additional network security controls such as Network Access Control (NAC) and Intrusion Detection/Prevention Systems (IDS/IPS) to detect anomalous activity targeting Aruba devices. 8. Regularly review and update firmware and software on all network devices to minimize exposure to known vulnerabilities. 9. Coordinate with supply chain and procurement teams to ensure future acquisitions consider security posture and patch management capabilities of network equipment vendors.
