Descriptions
Vulnerability in the Oracle VM VirtualBox product of Oracle Virtualization (component: Core). Supported versions that are affected are Prior to 6.1.38. Difficult to exploit vulnerability allows high 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 (scope change). Successful attacks of this vulnerability can result in takeover of Oracle VM VirtualBox. CVSS 3.1 Base Score 7.5 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:H/PR:H/UI:N/S:C/C:H/I:H/A:H).
Una vulnerabilidad en el producto Oracle VM VirtualBox de Oracle Virtualization (componente: Core). Las versiones soportadas que están afectadas son anteriores a 6.1.38. Una vulnerabilidad difícil de explotar permite que un atacante con altos privilegios que inicie sesión en la infraestructura donde es ejecutado Oracle VM VirtualBox pueda comprometer a Oracle VM VirtualBox. Mientras la vulnerabilidad está en Oracle VM VirtualBox, los ataques pueden afectar significativamente a otros productos (cambio de alcance). Los ataques con éxito de esta vulnerabilidad pueden resultar en la toma de control de Oracle VM VirtualBox. CVSS 3.1 Puntuación Base 7.5 (Impactos en la Confidencialidad, Integridad y Disponibilidad). Vector CVSS: (CVSS:3.1/AV:L/AC:H/PR:H/UI:N/S:C/C:H/I:H/A:H)
This vulnerability allows local attackers to escalate privileges on affected installations of Oracle VirtualBox. An attacker must first obtain the ability to execute high-privileged code on the target guest system in order to exploit this vulnerability.
The specific flaw exists within the PGMPhysRead function. The issue results from the lack of proper validation of user-supplied data, which can result in a write past the end of an allocated buffer. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of the hypervisor.
