Local takeover requiring user interaction

Published Oct 18, 2022 · Updated Sep 23, 2024

Improper access control in Oracle VM VirtualBox Core before 6.1.40 allows local users to take over VirtualBox on Windows hosts. Oracle has not published the affected Core locus or the access-control operation that mishandles attacker-controlled input. Exploitation requires low-privilege host logon and interaction by another person; successful attacks compromise VirtualBox confidentiality, integrity, and availability.
