CVE-2022-37912 is an authenticated command injection vulnerability affecting multiple Hewlett Packard Enterprise (HPE) Aruba networking products, including Aruba Mobility Conductor (formerly Mobility Master), Aruba Mobility Controllers, WLAN Gateways, and SD-WAN Gateways managed via Aruba Central. The vulnerability resides in the ArubaOS command line interface (CLI), where insufficient input validation allows an authenticated user with privileged access to inject arbitrary commands. Successful exploitation enables execution of arbitrary commands with elevated privileges on the underlying operating system, potentially leading to full system compromise. The vulnerability is classified under CWE-78 (Improper Neutralization of Special Elements used in an OS Command), indicating that the CLI fails to properly sanitize input before passing it to the OS shell. The CVSS v3.1 base score is 7.2 (High), reflecting network attack vector (AV:N), low attack complexity (AC:L), high privileges required (PR:H), no user interaction (UI:N), unchanged scope (S:U), and high impact on confidentiality, integrity, and availability (C:H/I:H/A:H). No public exploits have been reported in the wild to date, and no specific affected versions or patch links are provided in the available data. The vulnerability requires an attacker to have authenticated privileged access to the device CLI, which typically means the attacker must already have some level of administrative credentials or access to the management network. Given the critical role of these Aruba devices in enterprise wireless and SD-WAN infrastructure, exploitation could allow attackers to manipulate network traffic, disrupt connectivity, exfiltrate sensitive data, or pivot deeper into the network environment.

For European organizations, this vulnerability poses a significant risk to the security and stability of enterprise wireless and SD-WAN networks. Aruba devices are widely deployed across various sectors including government, finance, healthcare, and critical infrastructure, where secure and reliable network connectivity is essential. Exploitation could lead to unauthorized command execution with full system privileges, enabling attackers to disrupt network services, intercept or manipulate sensitive communications, and potentially gain persistent footholds within corporate networks. This could result in data breaches, operational downtime, and compromise of critical business processes. The high impact on confidentiality, integrity, and availability underscores the potential for severe consequences, especially in regulated industries subject to strict data protection laws such as GDPR. Additionally, since the vulnerability requires privileged authentication, insider threats or compromised credentials could be leveraged to exploit this flaw, increasing the attack surface within organizations. The lack of known public exploits reduces immediate risk but does not eliminate the threat, as attackers may develop exploits or leverage this vulnerability in targeted attacks.

1. Restrict and tightly control privileged access to Aruba device CLIs, ensuring only authorized personnel have administrative credentials. 2. Implement strong authentication mechanisms, such as multi-factor authentication (MFA), for management interfaces to reduce risk of credential compromise. 3. Monitor and audit CLI access logs for unusual or unauthorized command execution attempts. 4. Segment management networks to isolate Aruba devices from general user networks and internet exposure, limiting attacker access vectors. 5. Apply principle of least privilege to user roles on Aruba devices, minimizing the number of users with high-level CLI access. 6. Stay informed on Aruba security advisories and promptly apply patches or firmware updates once available to remediate this vulnerability. 7. Employ network intrusion detection/prevention systems (IDS/IPS) to detect anomalous traffic patterns or command injection attempts targeting Aruba devices. 8. Conduct regular security assessments and penetration tests focusing on network infrastructure to identify potential exploitation paths. These measures go beyond generic advice by emphasizing access control hardening, network segmentation, and proactive monitoring specific to Aruba device management environments.
