Third-party Vulnerability

Netlogon Elevation of Privilege Vulnerability (Zerologon)


BD is aware of and currently monitoring the Microsoft Netlogon elevation of privilege vulnerability (also known as Zerologon), affecting Netlogon Remote Protocol (MS-NRPC). This third-party vulnerability, which Microsoft is correcting through a phased two-part roll out that started on Aug. 11, 2020, is not specific to BD or our products. Additionally, we have not received any reports regarding this vulnerability being exploited on BD products.

CVE-2020-1472 is an elevation of privilege vulnerability that could allow an unauthorized user to establish a vulnerable Netlogon secure channel connection to a domain controller using the Netlogon Remote Protocol (MS-NRPC). To exploit the vulnerability, an unauthenticated attacker would need to use MS-NRPC to connect to a domain controller to obtain domain administrator access.

This vulnerability could potentially allow an attacker to run a specially crafted application on a device on the network.

This vulnerability was recently added to the list of third-party vulnerabilities threat actors could potentially use to infect systems with Ryuk Ransomware. For more information, please see our Ryuk Ransomware bulletin.


Please see the Product Security Patching website for all available product security patches. Additionally, we recommend the following compensating controls for customers using BD products that utilize Netlogon Remote Protocol:

  • Implement or perform Deep Packet Inspection on your firewall product.
  • Monitor Domain Controller logs for activity related to this vulnerability. Especially on events containing the fields Security ID: ANONYMOUS LOGON, Account Name: ANONYMOUS LOGON or Account Domain: NT AUTHORITY.
  • Do not authorize untrusted devices to make use of the Domain Controllers.
  • Enable “Enforcement Mode.” Microsoft’s Change Management Guidance provides details for organizations to implement “Enforcement Mode” immediately.
