6 Critical Facts About the Microsoft Zerologon Vulnerability

The Microsoft Zerologon vulnerability has been making headlines lately due to its potential to create serious security issues for organizations utilizing Windows-based systems. Here are six key things to know about this critical security flaw:

What is the Microsoft Zerologon Vulnerability?

The Microsoft Zerologon vulnerability, officially known as CVE-2020-1472, is a critical security flaw in the Netlogon authentication process within the Windows Server operating system. This vulnerability allows an attacker to impersonate the identity of any computer on a network when trying to authenticate against a Windows server, potentially gaining full control over the targeted domain controller.

How Does Zerologon Work?

Zerologon takes advantage of a flaw in the cryptographic algorithm used by the Netlogon authentication process, allowing an attacker to manipulate communications between a domain controller and client machines. By sending a series of crafted Netlogon messages, an attacker can trick the domain controller into changing its computer password to a blank value, effectively granting the attacker unauthorized access to the network.

Why is Zerologon Considered Dangerous?

Zerologon poses a severe threat to organizations using Windows servers, as it enables attackers to easily gain administrative privileges and take full control of the domain. Once an attacker has successfully exploited the vulnerability, they can install malware, steal sensitive data, disrupt operations, or even launch more sophisticated attacks within the compromised network.
