Name of the Vulnerable Software and Affected Versions Oracle VM VirtualBox versions prior to 6.1.28

Description The issue is related to insufficient input validation in the Core component of Oracle VM VirtualBox, allowing an attacker to gain full control over the application. This vulnerability can be easily exploited by a low-privileged attacker with logon access to the infrastructure where Oracle VM VirtualBox is executed, resulting in the takeover of Oracle VM VirtualBox. It is noted that this vulnerability does not apply to Windows systems.

Recommendations For versions prior to 6.1.28, update to version 6.1.28 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.
