Senserva AI Opinion for CVE-2024-38231

This flaw hits the Remote Desktop Licensing Service on Windows Server 2019 and 2022, which many organizations run on dedicated RDS licensing hosts that are often reachable inside the network and sometimes exposed externally. Despite the Denial of Service label, it carries a Critical rating of CVSS 9.8 and a 71 percent EPSS exploit probability, so weaponization is a realistic near-term risk even though it is not yet in CISA KEV or tied to ransomware.

Do this: Apply the Microsoft patch to all Remote Desktop Licensing hosts running Windows Server 2019 and 2022, and restrict access to the licensing service to trusted management networks.
