How to Fix CVE-2023-30547

To remediate this vulnerability, upgrade all affected Vm2 dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

vm2 fixed: 3.9.17 
npm install vm2@3.9.17
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls vm2

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2023-30547, inspect your project dependencies using npm:

npm ls vm2

Analyze the terminal output to locate any version of Vm2 in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.9.17), your application is affected.

Note: The npm ls vm2 command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection'), where the product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component. In Vm2, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

There exists a vulnerability in exception sanitization of vm2 for versions up to 3.9.16, allowing attackers to raise an unsanitized host exception inside `handleException()` which can be used to escape the sandbox and run arbitrary code in host context. ### Impact A threat actor can bypass the sandbox protections to gain remote code execution rights on the host running the sandbox. ### Patches This vulnerability was patched in the release of version `3.9.17` of `vm2`. ### Workarounds None. ### References PoC - https://gist.github.com/leesh3288/381b230b04936dd4d74aaf90cc8bb244 ### For more information If you have any questions or comments about this advisory: - Open an issue in [VM2](https://github.com/patriksimek/vm2) Thanks to [Xion](https://twitter.com/0x10n) (SeungHyun Lee) of [KAIST Hacking Lab](https://kaist-hacking.github.io/) for disclosing this vulnerability.
