Frequently Asked Questions
Who can exploit this vulnerability?
An attacker must already be authorized on the affected Windows system and able to execute an attack locally. The available data does not indicate that it is remotely exploitable.
What level of impact could successful exploitation have?
Successful exploitation can elevate the attacker's privileges. The supplied vector rates confidentiality, integrity, and availability impacts as high.
Which systems should be reviewed for exposure?
Review Microsoft Windows 10 and Windows 11 endpoints, along with Windows Server 2012, 2012 R2, 2016, 2019, 2022, and 2025 systems. The issue is associated with the Windows Routing and Remote Access Service (RRAS).
Does exploitation require user interaction?
No user interaction is required according to the supplied vector. Exploitation does require low attacker privileges and has high attack complexity.
