Background

pxdbench is a Python package available on PyPI that is designed for benchmarking and performance testing. However, it has been identified as containing malicious code that compromises user data. The package is intended to be installed via pip, but its true functionality is overshadowed by its harmful behavior, which includes exfiltrating sensitive information from the host system.

Vulnerability Detail

The vulnerability in the pxdbench package arises from its malicious code that executes during installation. This code is designed to exfiltrate basic information about the host, such as the IP address and username, without the user's consent. The package overrides the install command in setup.py, ensuring that the malicious code runs whenever the package is installed. This poses a risk to users who may unknowingly install the package, leading to potential data breaches and privacy violations.

How To Fix

This package is malicious. Remove it and rotate any credentials it could have accessed.

pip uninstall pxdbench

If it arrived as a transitive dependency, remove the package that pulled it in, then reinstall.
