Senserva AI Opinion for CVE-2025-53153

A fourth entry in this RRAS information disclosure series, still Critical 9.8 and 36 percent EPSS, targets the same Windows Server 2019 and Server 2022 builds as its siblings. The consistency of severity and EPSS score across this run suggests Microsoft is closing out a batch of related findings discovered in the same audit of the RRAS codebase. It has not been confirmed exploited or linked to ransomware.

Do this: Patch RRAS on Server 2019 and Server 2022 as a single update covering this and the other related RRAS CVEs in this batch.
