Background
The test1ro package is an npm module that is designed for use in JavaScript applications. It is typically utilized for various functionalities within the Node.js ecosystem. However, this package has been found to contain malicious code that can compromise the security of systems using it. The vulnerability arises from preinstall and postinstall hooks that execute code without user consent, potentially leading to data leakage and unauthorized access.
Vulnerability Detail
The vulnerability in the test1ro package stems from its preinstall and postinstall hooks that execute a script (node index.js) during the npm install process. This script retrieves the host's identifier using os.hostname() and sends it to a hardcoded external server (http://eo8f3m3ho26a0nm.m.pipedream.net/<package>?h=<hostname>). This behavior allows the attacker to collect sensitive information about the user's environment without their knowledge. The package also uses a high version number (999.99.99) to exploit dependency confusion, which could lead to the installation of malicious code instead of the intended internal package.
How To Fix
This package is malicious. Remove it and rotate any credentials it could have accessed.
npm uninstall test1ro
If it arrived as a transitive dependency, remove the package that pulled it in, then reinstall.
