CVE-2022-37919 is a vulnerability identified in the API of Hewlett Packard Enterprise's Aruba EdgeConnect Enterprise Software, specifically affecting versions ECOS 9.2.1.0 and below, ECOS 9.1.3.0 and below, ECOS 9.0.7.0 and below, and ECOS 8.3.7.1 and below. The vulnerability resides in the web-based management interface of the appliance, allowing an unauthenticated attacker to exploit the API to induce a denial-of-service (DoS) condition. This DoS condition prevents the affected appliance from properly responding to legitimate API requests, effectively disrupting normal management and operational functions. Since the attack vector does not require authentication or user interaction, it can be executed remotely by an attacker with network access to the management interface. The vulnerability impacts the availability of the Aruba EdgeConnect Enterprise appliance, a critical component in software-defined wide area network (SD-WAN) solutions used to optimize and secure enterprise network traffic. No known exploits have been reported in the wild as of the publication date, and no official patches or remediation links were provided in the source information. The vulnerability is classified as medium severity, reflecting its impact on availability but limited to denial-of-service without direct compromise of confidentiality or integrity.

For European organizations, the exploitation of CVE-2022-37919 could lead to significant operational disruptions, especially for enterprises relying on Aruba EdgeConnect Enterprise for SD-WAN management and network optimization. The denial-of-service condition could result in loss of centralized control over network traffic routing, degraded network performance, and potential downtime of critical business applications dependent on the SD-WAN infrastructure. This could affect sectors with high dependency on network availability such as finance, manufacturing, healthcare, and telecommunications. Additionally, disruption in network management could delay incident response and remediation efforts during concurrent security incidents. While the vulnerability does not directly expose sensitive data or allow unauthorized access, the loss of availability can indirectly impact business continuity and service level agreements. Given the unauthenticated nature of the exploit, attackers could launch DoS attacks without prior access, increasing the risk profile for organizations with exposed or poorly segmented management interfaces.

European organizations should implement the following specific mitigation measures: 1) Immediately restrict access to the Aruba EdgeConnect Enterprise web-based management interface by enforcing strict network segmentation and firewall rules, allowing only trusted administrative IP addresses to connect. 2) Deploy virtual private networks (VPNs) or zero-trust network access (ZTNA) solutions to secure remote management access, preventing direct exposure of the management interface to untrusted networks. 3) Monitor network traffic and API request patterns for anomalies indicative of DoS attempts targeting the management interface, enabling rapid detection and response. 4) Engage with Hewlett Packard Enterprise support channels to obtain any available patches or firmware updates addressing this vulnerability, and plan timely deployment once available. 5) Implement rate limiting or API request throttling where possible to mitigate the impact of excessive or malicious API calls. 6) Maintain an up-to-date inventory of affected Aruba EdgeConnect appliances and verify their software versions to prioritize remediation efforts. 7) Conduct regular security assessments and penetration testing focusing on management interfaces to identify and remediate similar vulnerabilities proactively.
