Senserva AI Opinion for CVE-2025-29835

This information disclosure bug is in the Remote Access Connection Manager rather than RRAS itself, though it shares the same 58 percent EPSS score and affected Windows 10 1809 and Server 2019 systems as the elevated RRAS cluster nearby in this list. Connection Manager handles dial up and VPN connection profiles, so exposure depends on whether those legacy connection types are configured.

Do this: Check whether Remote Access Connection Manager profiles are actually configured on affected systems, and patch regardless given the 58 percent EPSS score.
