Data disclosure through undisclosed Core flaw
Published Apr 22, 2021 · Updated Sep 26, 2024
Information disclosure in Oracle VM VirtualBox Core before 6.1.20 allows local users to read all data accessible to the hypervisor. Oracle has not published the affected function, attacker-controlled input, or incorrect operation within the Core component. Exploitation requires high privileges and logon to the host infrastructure, and the disclosure can cross product boundaries.
