Frequently Asked Questions
Which systems should be prioritized for review?
Prioritize Microsoft Windows systems running affected versions: Windows 10, Windows 11, and Windows Server 2012, 2012 R2, 2016, 2019, 2022, and 2025. The issue is in the Routing and Remote Access Service (RRAS), so systems where that service is used should receive particular attention.
What level of access does an attacker need?
The vector is network-based, attack complexity is low, and no user interaction is required. However, the provided severity vector indicates the attacker needs low-level privileges before exploitation.
What is the potential impact of successful exploitation?
Successful exploitation can result in remote code execution and unauthorized access to the affected machine. The supplied impact ratings indicate high potential impact to confidentiality, integrity, and availability.
Does the provided information confirm that RRAS is enabled by default or provide a workaround?
No. The provided data identifies RRAS as the affected component but does not state whether it is enabled by default, list affected build numbers, or provide mitigations or workarounds.
