Frequently Asked Questions
Who is realistically exposed to this vulnerability?
Systems running Microsoft Windows 10, Windows Server 2016, or Windows Server 2019 are identified as affected. Exploitation requires local access and low privileges, so it is primarily a post-compromise or local-user risk rather than a remote unauthenticated attack.
What does an attacker need to do to exploit it?
An attacker must be able to run a specially crafted application on the victim system. No user interaction is required once the attacker has the necessary local access.
What is the impact of successful exploitation?
A successful attacker could run arbitrary code in an elevated context. The CVSS vector indicates high impact to confidentiality, integrity, and availability.
What remediation is identified?
Apply the security update that corrects how the Windows State Repository Service handles objects in memory. The provided data does not identify a workaround or mitigation for systems that cannot yet be patched.
