CVE-2023-32314 : Exploit Details and Defense Strategies

A critical vulnerability, CVE-2023-32314, exists in the

vm2

sandbox escape feature, allowing threat actors to execute remote code. This article delves into the impact, technical details, and mitigation strategies for this CVE.

Understanding CVE-2023-32314

The CVE-2023-32314 vulnerability targets the

vm2

environment, enabling attackers to escape the sandbox and execute malicious code remotely.

What is CVE-2023-32314?

The

vm2

sandbox, designed to run untrusted code with Node's built-in modules, contains a vulnerability in versions up to 3.9.17. Exploiting an unexpected object creation due to the

Proxy

specification allows threat actors to bypass sandbox protections, gaining remote code execution capabilities on the host system.

The Impact of CVE-2023-32314

The impact of this vulnerability is critical, with a CVSS v3.1 base score of 9.8 (Critical). It poses high confidentiality, integrity, and availability risks, requiring immediate attention to prevent potential exploitation.

Technical Details of CVE-2023-32314

This section explores the specifics of the CVE, including the vulnerability description, affected systems, and the exploitation mechanism.

Vulnerability Description

The CVE-2023-32314 vulnerability in

vm2

up to version 3.9.17 allows threat actors to exploit the creation of a host object via the

Proxy

specification, leading to unauthorized remote code execution.

Affected Systems and Versions
