Node.js Systeminformation - Command Injection (CVE-2021-21315)

Node.js server is affected by a Command Injection vulnerability, located in the System Information Library for Node.JS (npm package "systeminformation"), that an unauthenticated attacker can exploit to execute arbitrary commands on the target server. Systeminformation is an open source collection of functions that is used to retrieve hardware, system and OS information. The root cause of this vulnerability consists in insufficient sanitization of the URL.

Sniper can gain unauthenticated Remote Code Execution on the target system and extract multiple artefacts as evidence.

The risk exists that a remote unauthenticated attacker can fully compromise the server in order to steal confidential information, install ransomware or pivot to the internal network.

Upgrade the "systeminformation" package to version 5.3.1 or above.
