CVE-2022-37924 is a vulnerability identified in 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 command line interface (CLI) of the Aruba EdgeConnect Enterprise platform, which is used for managing and configuring SD-WAN (Software-Defined Wide Area Network) appliances. The flaw allows remote authenticated users to execute arbitrary commands on the underlying host operating system with root privileges. This is due to improper input validation or command injection weaknesses, categorized under CWE-78 (Improper Neutralization of Special Elements used in an OS Command). Exploiting this vulnerability could lead to complete system compromise, enabling attackers to manipulate network traffic, disrupt services, or pivot into internal networks. Although exploitation requires authentication, the elevated privileges gained post-exploitation significantly increase the risk. There are no known public exploits or active exploitation campaigns reported as of the publication date (November 30, 2022). The vulnerability affects critical network infrastructure components that are integral to enterprise WAN management and security, making it a significant concern for organizations relying on Aruba EdgeConnect for their network operations.

For European organizations, the impact of this vulnerability could be substantial. Aruba EdgeConnect Enterprise Software is widely deployed in enterprise and service provider networks to manage SD-WAN infrastructure, which is critical for ensuring secure and reliable connectivity across distributed sites. Successful exploitation could lead to full system compromise, allowing attackers to disrupt network operations, intercept or manipulate sensitive data, and potentially launch further attacks within the corporate network. This could result in operational downtime, data breaches, and loss of trust from customers and partners. Given the reliance on SD-WAN for digital transformation and cloud connectivity, the vulnerability could affect sectors such as finance, telecommunications, manufacturing, and government agencies. The requirement for authentication limits exposure to external unauthenticated attackers but does not eliminate risk, especially in scenarios where credentials are compromised or insider threats exist. The lack of known exploits suggests a window of opportunity for defenders to patch and mitigate before widespread attacks occur.

1. Immediate patching: Organizations should upgrade Aruba EdgeConnect Enterprise Software to the latest versions beyond the affected releases, as vendors typically release patches addressing such vulnerabilities. 2. Restrict CLI access: Limit CLI access to trusted administrators only, using network segmentation and access control lists (ACLs) to reduce the attack surface. 3. Implement strong authentication: Enforce multi-factor authentication (MFA) for all users accessing the management interface to reduce the risk of credential compromise. 4. Monitor and audit: Enable detailed logging and continuous monitoring of CLI access and command execution to detect anomalous activities promptly. 5. Credential hygiene: Regularly rotate administrative credentials and ensure they are stored securely. 6. Network segmentation: Isolate management interfaces from general user networks and the internet to prevent unauthorized access. 7. Incident response readiness: Prepare and test incident response plans specifically for network infrastructure compromise scenarios. 8. Vendor communication: Stay updated with Hewlett Packard Enterprise advisories for any patches or mitigation guidance and apply them promptly.
