Command Injection Vulnerability

Basic Information

CVE State: PUBLISHED
Reserved Date: December 22, 2020
Published Date: February 16, 2021
Last Updated: February 06, 2025
Vendor: sebhildebrandt
Product: systeminformation
Description: The System Information Library for Node.JS (npm package "systeminformation") is an open source collection of functions to retrieve detailed hardware, system and OS information. In systeminformation before version 5.3.1 there is a command injection vulnerability. Problem was fixed in 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.
