📋 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.

How can I verify that the update is installed? Customers wanting to ensure the client has been updated can run the MDE Client Analyzer on the device. When running the analyzer on a Windows device that does not have the security update, the analyzer will present a warning (ID 121035) indicating missing patch and directing to relevant online article. Additionally, if the update is installed, but the Anti-Spoofing capability is not in a stable state, the analyzer will present warning (ID 121036) indicating an issue and providing additional online guidance or callout to reach out to Microsoft support if issue persists.
