Frequently Asked Questions
Who is exposed to this vulnerability?
Systems running the affected Microsoft Windows client or server products are exposed if a local attacker can authenticate to the system. The issue is locally exploitable and does not require user interaction.
What level of access does an attacker need?
An attacker must already be authorized on the affected machine with low privileges. Successful exploitation can elevate those local privileges and affect confidentiality, integrity, and availability.
Is this remotely exploitable?
The provided vector identifies local attack access, so exploitation requires access to the affected Windows system rather than network-only access.
