CVE-2021-2409: Oracle VirtualBox NAT Numeric Truncation Privilege Escalation Vulnerability

First published: Tue Jul 20 2021(Updated: )

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 implementation of NAT. The issue results from the lack of proper validation of user-supplied data, which can result in a numeric truncation before writing to memory. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of the hypervisor.
