[ Why it matters ]Priority signals

  • Exploited in the wild: on CISA's Known Exploited Vulnerabilities list since 2022-01-18
  • EPSS: 91% chance of exploitation in the next 30 days (higher than 100% of CVEs)

[ Description ]Official 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.

CISA: In this vulnerability, an attacker can send a malicious payload that will exploit the name parameter. After successful exploitation, attackers can execute remote.
