Background
better-envforge is an npm package designed as a dotenv-style environment configuration toolkit, allowing developers to manage environment variables easily. However, it has been found to contain malicious code that disguises itself under a different name, node-env-buffer, leading to significant security risks for users who install and utilize this package.
Vulnerability Detail
The vulnerability originates from the better-envforge package version 1.0.0, which contains malicious code embedded within its files. When the package is required or the CLI command 'dot2env' is executed, it reads a JPEG file to extract a base64-encoded PowerShell command. This command is executed via a self-deleting VBS script that runs PowerShell with attacker-controlled commands. This poses a severe risk as any Windows host that imports this package will execute the malicious code, potentially leading to unauthorized access and control over the system.
How To Fix
This package is malicious. Remove it and rotate any credentials it could have accessed.
npm uninstall better-envforgeIf it arrived as a transitive dependency, remove the package that pulled it in, then reinstall.
