An attacker who successfully exploited the vulnerability could run a specially crafted application on a device on the network.\nTo exploit the vulnerability, an unauthenticated attacker would be required to use MS-NRPC to connect to a domain controller to obtain domain administrator access.\nMicrosoft is addressing the vulnerability in a phased two-part rollout. These updates address the vulnerability by modifying how Netlogon handles the usage of Netlogon secure channels.\nFor guidelines on how to manage the changes required for this vulnerability and more information on the phased rollout, see  How to manage the changes in Netlogon secure channel connections associated with CVE-2020-1472 (updated September 28, 2020).\nWhen the second phase of Windows updates become available in Q1 2021, customers will be notified via a revision to this security vulnerability.
