📋 Description

According to the CVSS metric, the attack complexity is high (AC:H). What does that mean for this vulnerability? Successful exploitation of this vulnerability requires an attacker to gather information specific to the environment of the targeted component.

According to the CVSS metric, the attack vector is local (AV:L). Why does the CVE title indicate that this is a remote code execution? The word Remote in the title refers to the location of the attacker. This type of exploit is sometimes referred to as Arbitrary Code Execution (ACE). The attack itself is carried out locally. For example, when the score indicates that the Attack Vector is Local and User Interaction is Required, this could describe an exploit in which an attacker, through social engineering, convinces a victim to download and open a specially crafted file from a website which leads to a local attack on their computer.

How do I know if my system is affected by this vulnerability? For systems running Remote Desktop Connection, the server is secure by default. Systems are vulnerable when an administrator has enabled Restricted Admin or Windows Defender Remote Credential Guard on the remote host by using the Registry key setting (DWORD value named "DisableRestrictedAdmin") as outlined in Protect Remote Desktop credentials with Windows Defender Remote Credential Guard.
