• Severity: high (CVSS 7.8 v3.1)
• Exploited in the wild: yes — in CISA KEV since 2022-01-18
• EPSS: 90.7% probability of exploitation in the next 30 days
• Public exploit or detection template: yes
• Published: 2021-02-16 · updated 2026-06-17
• Weakness: CWE-78

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.

Affected products

• Apache Software Foundation Apache Cordova Android: 10.0.0
• sebhildebrandt systeminformation: before 5.3.1 — fixed in 5.3.1

How to fix

Upgrade to a fixed version: sebhildebrandt systeminformation 5.3.1. Check the vendor advisory for mitigations.
