Frequently Asked Questions
What level of access does an attacker need before exploitation?
The CVSS vector indicates low privileges are required. The attacker does not need user interaction, but exploitation has high attack complexity.
Which systems should be prioritized for review?
The affected software list includes Microsoft Windows 10, Windows 11, and Windows Server 2012 through Windows Server 2025, including 2012 R2, 2016, 2019, and 2022. Systems running RRAS should be assessed first because the issue is in that service.
What is the potential impact if exploitation succeeds?
Successful exploitation can result in remote code execution and unauthorized access to the affected machine. The supplied CVSS metrics rate confidentiality, integrity, and availability impact as high.
