Senserva AI Opinion for CVE-2024-49120

Another member of the nine-flaw Remote Desktop Services batch: Critical, CVSS 9.8, Server 2019 and 2022, EPSS 84 percent. The bugs cluster in the RD Gateway connection handling path, and gateways are by definition exposed to the outside world so remote workers can reach them. For this CVE the differentiator is simply exposure: if your gateway is patched, focus shifts to the session hosts behind it.

Do this: After confirming gateways are patched, extend verification to internal RD Session Hosts on 2019 and 2022 that may sit in slower patch rings.
