CVE-2023-21898

Name of the Vulnerable Software and Affected Versions Oracle VM VirtualBox versions prior to 6.1.42 Oracle VM VirtualBox versions prior to 7.0.6

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 the ability to cause a hang or frequently repeatable crash of Oracle VM VirtualBox, leading to a denial of service. This issue applies to VirtualBox VMs running Windows 7 and later.

Recommendations For Oracle VM VirtualBox versions prior to 6.1.42, update to version 6.1.42 or later. For Oracle VM VirtualBox versions prior to 7.0.6, update to version 7.0.6 or later. As a temporary workaround, consider restricting access to the Core component of Oracle VM VirtualBox to minimize the risk of exploitation.
