Upgrade systeminformation to version 5.31.7 or higher.
Overview
systeminformation is a simple system and OS information library.
Affected versions of this package are vulnerable to Command Injection through the checkLinuxDCHPInterfaces() function in lib/network.js. An attacker can execute arbitrary commands by supplying a malicious source path in a Linux interfaces(5) configuration file that networkInterfaces() parses. The vulnerable code reads /etc/network/interfaces and recursively follows source directives, then interpolates the parsed path unquoted into a shell command passed to execSync(). Any process calling networkInterfaces() on a system where an attacker can influence a sourced interfaces file can be made to run injected commands with the privileges of that Node.js process.
