Name of the Vulnerable Software and Affected Versions: Oracle VM VirtualBox versions prior to 6.1.20

Description: The issue is related to insufficient input validation in the Core component of Oracle VM VirtualBox, allowing a low-privileged attacker with logon access to the infrastructure to compromise Oracle VM VirtualBox. Successful attacks can result in unauthorized access to critical data or complete access to all Oracle VM VirtualBox accessible data.

Recommendations: For versions prior to 6.1.20, update to version 6.1.20 or later to resolve the issue. As a temporary workaround, consider restricting access to the Core component of Oracle VM VirtualBox to minimize the risk of exploitation.
