Local privilege escalation through undisclosed RasMan flaw
Published Dec 15, 2021 · Updated Aug 4, 2024
Elevation of privilege in Microsoft Windows Remote Access Connection Manager allows local users to gain elevated privileges. Microsoft identifies RasMan as the affected component but has not disclosed the vulnerable code locus or wrong operation performed on attacker-controlled input. Exploitation requires existing low-privilege local access and grants control at a higher privilege level, affecting system confidentiality, integrity, and availability.
