Frequently Asked Questions
Which systems should be assessed for exposure?
Assess Microsoft Windows 10, Windows 11, and Windows Server 2012 R2, 2016, 2019, 2022, and 2025 systems that use the Microsoft Windows Key Storage Provider.
Does exploitation require local access?
Yes. The reported attack vector is local, so the attacker must be able to execute or interact with the affected system locally rather than exploit it solely over the network.
What level of access and effort does exploitation require?
The vulnerability requires low privileges and has high attack complexity. No user interaction is required, and the stated impact is disclosure of information rather than modification of data or service disruption.
