Descriptions

Vulnerability in the Oracle VM VirtualBox component of Oracle Virtualization (subcomponent: Core). Supported versions that are affected are Prior to 5.2.28 and prior to 6.0.6. Easily exploitable vulnerability allows low privileged attacker with logon to the infrastructure where Oracle VM VirtualBox executes to compromise Oracle VM VirtualBox. While the vulnerability is in Oracle VM VirtualBox, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in takeover of Oracle VM VirtualBox. CVSS 3.0 Base Score 8.8 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H).

Vulnerabilidad en el componente Oracle VM VirtualBox de Oracle Virtualization (subcomponente: Core). Las versiones soportadas que se ven afectadas son las anteriores a la 5.2.28 y las anteriores a la 6.0.6. La vulnerabilidad fácilmente explotable permite a los atacantes con bajos privilegios acceder a la infraestructura donde se ejecuta Oracle VM VirtualBox para comprometer a Oracle VM VirtualBox. Aunque la vulnerabilidad se encuentra en Oracle VM VirtualBox, los ataques pueden tener un impacto significativo en productos adicionales. Los ataques exitosos de esta vulnerabilidad pueden resultar en la adquisición de Oracle VM VirtualBox. CVSS 3.0 Base Score 8.8 (Impactos de Confidencialidad, Integridad y Disponibilidad). Vector CVSS: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H).

This vulnerability allows local attackers to escalate privileges on vulnerable installations of Oracle VirtualBox. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.
The specific flaw exists within the handling of virtualized e1000 devices. The issue results from the lack of proper locking when performing operations on an object. An attacker can leverage this vulnerability to escalate privileges and execute code in the context of the hypervisor.
