Frequently Asked Questions
Who is exposed to this vulnerability?
Systems running the listed Microsoft Windows versions are affected: Windows 10 and Windows Server 2012, 2012 R2, 2016, and 2019. Exploitation is local, so the attacker must be able to run code on the target system.
What access does an attacker need to exploit it?
The attacker must already be authorized with low-level privileges on the affected Windows system. No user interaction is required, and successful exploitation can elevate the attacker's privileges locally.
