Unauthenticated DHCP service interruption via undisclosed requests
Published Apr 9, 2024 · Updated May 3, 2025
Denial of service in affected Microsoft Windows Server 2008 through 2022 DHCP Server builds allows remote attackers to interrupt DHCP service. Microsoft has not published the request-processing flaw or the specific network input that triggers the failure. Exploitation requires network access but no authentication or user interaction, and the documented consequence is limited to loss of DHCP service availability.
