CVE-2022-37909 is a medium-severity vulnerability affecting Hewlett Packard Enterprise's Aruba networking products, specifically the Aruba Mobility Conductor (formerly Mobility Master), Aruba Mobility Controllers, WLAN Gateways, and SD-WAN Gateways managed via Aruba Central. The vulnerability arises from certain configurations of ArubaOS, the operating system running on these devices, which can lead to the disclosure of sensitive information related to configured ESSIDs (Extended Service Set Identifiers). ESSIDs are the names of wireless networks broadcast by access points. The disclosure scenario is complex and depends on multiple factors outside the direct control of an attacker, indicating that exploitation is non-trivial and may require specific network conditions or configurations to be present. The vulnerability is classified under CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor). According to the CVSS v3.1 scoring, it has a score of 5.3 (medium severity), with the vector indicating that the attack requires adjacent network access (AV:A), high attack complexity (AC:H), no privileges required (PR:N), no user interaction (UI:N), and impacts confidentiality only (C:H), without affecting integrity or availability. No known exploits are reported in the wild, and no patches have been explicitly linked in the provided information. The vulnerability primarily risks unauthorized disclosure of sensitive wireless network configuration data, which could aid attackers in reconnaissance or further targeted attacks on the network infrastructure.

For European organizations, this vulnerability could lead to unauthorized disclosure of sensitive wireless network configuration information, such as ESSIDs, which may include internal or guest network identifiers. While the direct impact on confidentiality is significant, the lack of impact on integrity and availability limits the immediate operational disruption. However, the disclosed information could facilitate more sophisticated attacks, including targeted network intrusions or lateral movement within corporate environments. Organizations relying heavily on Aruba wireless infrastructure, especially those with complex or sensitive wireless deployments, may face increased risk of exposure of network topology or segmentation details. This is particularly relevant for sectors with stringent data protection requirements, such as finance, healthcare, and critical infrastructure. The requirement for adjacent network access reduces the risk from remote attackers but raises concerns about insider threats or attackers who have already gained limited network footholds. Given the strategic importance of secure wireless communications in modern enterprise environments, exploitation could undermine trust in network security and potentially expose sensitive operational details.

1. Review and audit ArubaOS configurations related to ESSIDs to identify and remediate any settings that could lead to sensitive information exposure. 2. Limit physical and wireless network access to trusted personnel and devices to reduce the risk of adjacent network exploitation. 3. Segment wireless networks appropriately, ensuring that sensitive ESSIDs are not broadcast or accessible in less secure network zones. 4. Implement strict network access controls and monitoring on wireless infrastructure to detect anomalous access patterns that could indicate reconnaissance or exploitation attempts. 5. Keep ArubaOS and Aruba Central management platforms updated with the latest firmware and software releases from Hewlett Packard Enterprise, monitoring for official patches addressing this vulnerability. 6. Employ network intrusion detection/prevention systems (IDS/IPS) tuned to detect suspicious activities around wireless network enumeration or configuration probing. 7. Educate network administrators on secure configuration best practices specific to Aruba products to prevent inadvertent exposure of sensitive wireless network information. 8. Where possible, restrict management interfaces of Aruba devices to secure management VLANs or out-of-band management networks to minimize exposure.
