Frequently Asked Questions
Who is exposed to this vulnerability?
Systems running the Microsoft Windows Update Orchestrator Service are exposed. Exploitation is local, so an attacker must already have authorized access to the affected system.
What level of access does an attacker need?
The attacker needs low privileges and local access. No user interaction is required for exploitation.
What is the likely impact of successful exploitation?
A successful attacker could elevate privileges locally. The provided severity vector indicates potential high impact to confidentiality, integrity, and availability.
How difficult is exploitation expected to be?
The supplied vector rates attack complexity as high. This indicates exploitation requires conditions beyond merely having local low-privileged access, although those conditions are not specified in the provided data.
