Assigner: GitHub, Inc.

Description

vm2 is an open source vm/sandbox for Node.js. Prior to version 3.11.0, VM2 suffers from a sandbox breakout vulnerability through the inspect function. This allows attackers to write code which can escape from the VM2 sandbox and execute arbitrary commands on the host system. This issue has been patched in version 3.11.0.

Attack-Flow Graph

Executive Summary

The vulnerability exists in vm2, an open source virtual machine and sandbox for Node.js. Prior to version 3.11.0, there is a sandbox breakout vulnerability through the inspect function. This means that attackers can write code that escapes the vm2 sandbox environment and execute arbitrary commands on the host system.

Mitigation Strategies

To mitigate this vulnerability, you should upgrade vm2 to version 3.11.0 or later, where the sandbox breakout issue through the inspect function has been patched.

Impact Analysis

This vulnerability can have severe impacts because it allows attackers to break out of the sandbox and run arbitrary commands on the host system. This can lead to full system compromise, unauthorized access to sensitive data, disruption of services, and potentially complete control over the affected system.

Compliance Impact

The vulnerability in vm2 allows attackers to escape the sandbox and execute arbitrary commands on the host system, which can lead to unauthorized access and control over sensitive data.

Such unauthorized access and potential data breaches could negatively impact compliance with standards and regulations like GDPR and HIPAA, which require strict controls to protect sensitive personal and health information.

However, specific impacts on compliance depend on the context in which vm2 is used and the nature of the data processed.
