Descriptions
Vulnerability in the Oracle VM VirtualBox product of Oracle Virtualization (component: Core). Supported versions that are affected are Prior to 5.2.40, prior to 6.0.20 and prior to 6.1.6. Easily exploitable 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. Successful attacks of this vulnerability can result in takeover of Oracle VM VirtualBox. CVSS 3.0 Base Score 6.0 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:H/UI:N/S:C/C:H/I:N/A:N).
Vulnerabilidad en el producto Oracle VM VirtualBox de Oracle Virtualization (componente: Core). Las versiones compatibles afectadas son anteriores a la versión 5.2.40, anteriores a la versión 6.0.20 y anteriores a la versión 6.1.6. La vulnerabilidad fácilmente explotable permite a los atacantes con privilegios elevados iniciar sesión en la infraestructura donde se ejecuta Oracle VM VirtualBox para comprometer Oracle VM VirtualBox. Si bien la vulnerabilidad se encuentra en Oracle VM VirtualBox, los ataques pueden afectar significativamente a productos adicionales. Los ataques con éxito de esta vulnerabilidad pueden resultar en la adquisición de Oracle VM VirtualBox. CVSS 3.0 Base Score 6.0 (Impactos de confidencialidad, integridad y disponibilidad). Vector CVSS: (CVSS: 3.0 / AV: L / AC: L / PR: H / UI: N / S: C / C: H / I: N / A: N).
This vulnerability allows local attackers to disclose sensitive information 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 IP checksums in the virtualized e1000 network interface. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated buffer. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of the hypervisor.
