Unauthenticated service interruption via undisclosed SSTP flaw
Published Apr 11, 2023 · Updated Jan 23, 2025
Denial of service in Microsoft Windows SSTP allows remote attackers to interrupt service by sending network traffic to an affected system. Microsoft has not published the specific SSTP message, parser locus, or incorrect operation that triggers the interruption. Network access without authentication is sufficient, and the published assessment reports no confidentiality or integrity impact.
