AI-suggested
- Immediately restrict network access to the HPE Aruba Networking Private 5G Core API to trusted and authenticated internal networks only, using firewalls and access control lists (ACLs).
- Implement strict network segmentation to isolate the 5G core infrastructure from general enterprise networks and the internet to reduce exposure.
- Deploy continuous monitoring and anomaly detection systems focused on API traffic to identify unusual or unauthorized access attempts.
- Conduct thorough audits of user roles and permissions within the 5G core environment to minimize privilege exposure.
- Prepare for rapid deployment of official patches or updates from HPE once released, including testing in controlled environments.
- Engage with HPE support and subscribe to security advisories to receive timely information on mitigation and patch availability.
- Consider deploying additional security layers such as Web Application Firewalls (WAFs) or API gateways that can enforce stricter validation and error handling.
- Train security teams on the specifics of private 5G core vulnerabilities and incident response procedures tailored to telecom infrastructure.
- Review and update incident response plans to include scenarios involving 5G core infrastructure compromise.
- Collaborate with telecom providers and industry groups to share threat intelligence related to private 5G core vulnerabilities.
Description
Vulnerabilities in the API error handling of an HPE Aruba Networking 5G Core server API could allow an unauthenticated remote attacker to obtain sensitive information. Successful exploitation could allow an attacker to access details such as user accounts, roles, and system configuration, as well as to gain insight into internal services and workflows, increasing the risk of unauthorized access and elevated privileges when combined with other vulnerabilities.
