CVE-2021-21315 – System Information Library for Node.JS Command Injection

https://notcve.org/view.php?id=CVE-2021-21315

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. • https://github.com/ForbiddenProgrammer/CVE-2021-21315-PoC https://github.com/alikarimi999/CVE-2021-21315 https://github.com/G01d3nW01f/CVE-2021-21315 https://github.com/MazX0p/CVE-2021-21315-exploit https://github.com/xMohamed0/CVE-2021-21315-POC https://github.com/sebhildebrandt/systeminformation/commit/07daa05fb06f24f96297abaa30c2ace8bfd8b525 https://github.com/sebhildebrandt/systeminformation/security/advisories/GHSA-2m8v-572m-ff2v https://lists.apache.org/thread.html/r8afea9a83ed568f2647cccc6d8d06126f9815715ddf9a4d479b26b05%40%3Cissu • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
