System Information Library for Node.JS Command Injection

KEVHIGH 7.8EPSS 90.7%

Does this matter?

Known to be exploited in the wild (CISA KEV, CISA remediation deadline 1 February 2022). Treat as an emergency change: patch or isolate now, then hunt for prior compromise.

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.
