Background
The cfgmgr-syn package, available on PyPI, is designed to manage configuration settings in Python applications. It is intended to simplify the process of handling configuration files and settings. However, this package has been found to contain malicious code that compromises user data, specifically by exfiltrating clipboard content to a hardcoded location.
Vulnerability Detail
The vulnerability originates from a malicious code snippet within the cfgmgr-syn package, specifically in versions 1.0.26 and 1.0.27. This code is obfuscated and includes a persistence mechanism, allowing it to remain active even after the initial execution. The primary risk associated with this vulnerability is clipboard-stealing, where sensitive information copied to the clipboard can be exfiltrated to an external server. The malicious code connects to an IP address (204.10.194.247) and sends the stolen data to a specified URL (http://204.10.194.247:8765). This poses a significant threat to user privacy and data security.
How To Fix
This package is malicious. Remove it and rotate any credentials it could have accessed.
pip uninstall cfgmgr-synIf it arrived as a transitive dependency, remove the package that pulled it in, then reinstall.
