CVE-2022-37899 is an authenticated command injection vulnerability affecting Hewlett Packard Enterprise's Aruba networking products, specifically the Aruba Mobility Conductor (formerly known as Mobility Master), Aruba Mobility Controllers, WLAN Gateways, and SD-WAN Gateways managed via Aruba Central. The vulnerability exists within the ArubaOS command line interface (CLI), where insufficient input validation allows an authenticated user with privileged access to inject arbitrary commands. Successful exploitation enables the attacker to execute 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, low attack complexity, high privileges required, no user interaction, and high impact on confidentiality, integrity, and availability. No known exploits are currently reported in the wild, and no specific affected versions or patches are listed in the provided data. However, given the critical nature of the affected devices as core network infrastructure components, exploitation could severely disrupt network operations and compromise sensitive data.

For European organizations, the impact of this vulnerability is significant due to the widespread use of Aruba networking equipment in enterprise and service provider environments. Successful exploitation could lead to unauthorized control over critical network infrastructure, enabling attackers to intercept, modify, or disrupt network traffic, exfiltrate sensitive information, or launch further attacks within the network. This could affect confidentiality by exposing sensitive communications, integrity by allowing manipulation of network configurations or data, and availability by causing network outages or degraded performance. Given the role of Aruba Mobility Controllers and SD-WAN Gateways in managing wireless and wide-area networks, disruption could impact business continuity, especially for sectors reliant on secure and stable connectivity such as finance, healthcare, manufacturing, and government. The requirement for authenticated privileged access limits the attack surface but does not eliminate risk, as insider threats or compromised credentials could be leveraged. Additionally, centralized management via Aruba Central increases the potential blast radius if the management platform is affected.

1. Implement strict access controls and least privilege principles to limit CLI access to trusted administrators only. 2. Enforce strong authentication mechanisms, including multi-factor authentication (MFA), for all privileged accounts managing Aruba devices. 3. Regularly audit and monitor CLI access logs for suspicious activity or unauthorized command execution attempts. 4. Segregate management networks to isolate Aruba infrastructure from general user networks, reducing exposure. 5. Apply any available vendor patches or firmware updates promptly once released, even though none are listed currently, monitor Hewlett Packard Enterprise advisories closely. 6. Use network segmentation and intrusion detection/prevention systems to detect anomalous traffic patterns indicative of exploitation attempts. 7. Conduct regular security training for administrators to recognize social engineering or credential compromise risks. 8. If possible, disable or restrict CLI commands that are not essential to reduce the attack surface. 9. Employ configuration management tools to maintain consistent and secure device configurations and quickly remediate unauthorized changes.
