Frequently Asked Questions
1
Who can exploit this vulnerability?
An attacker must already be authorized on the affected Windows system and have local access. The provided data does not indicate that it is exploitable remotely or without prior access.
2
Which systems should be prioritized for review?
Review Microsoft Windows 10, Windows 11, and Windows Server 2012, 2012 R2, 2016, 2019, 2022, and 2025 systems. Because successful exploitation can result in elevated privileges with high confidentiality, integrity, and availability impact, systems where lower-privileged users can log on locally are particularly relevant.
