critical Tenable Cloud Security Plugin ID 407067

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - An elevation of privilege vulnerability exists when an attacker establishes a vulnerable Netlogon secure
 channel connection to a domain controller, using the Netlogon Remote Protocol (MS-NRPC). An attacker who
 successfully exploited the vulnerability could run a specially crafted application on a device on the
 network. To exploit the vulnerability, an unauthenticated attacker would be required to use MS-NRPC to
 connect to a domain controller to obtain domain administrator access. Microsoft 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. For 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). When
 the second phase of Windows updates become available in Q1 2021, customers will be notified via a revision
 to this security vulnerability. If you wish to be notified when these updates are released, we recommend
 that you register for the security notifications mailer to be alerted of content changes to this advisory.
