Description

The npm package 'nativescript-swisspost-pcc-creative-editor' masquerades as an internal Swiss Post NativeScript package but contains malicious code. During installation, it executes arbitrary Node.js code that leaks the installer's project directory name to a third-party server. This package is a dependency-confusion attack that results in code execution and information disclosure on the installer's system. The package author labels it as a bug bounty proof of concept, but the impact is critical. Any system with this package installed should be considered fully compromised.

Impact

Installation of this package results in arbitrary Node.js code execution on the installer's machine and disclosure of the installer's project directory name to an external attacker-controlled server. This compromises the confidentiality and integrity of the affected system. The vendor advisory states that any computer with this package installed should be considered fully compromised, requiring immediate rotation of all secrets and keys from a different machine. Removal of the package alone does not guarantee full remediation due to potential persistent compromise.

Defensive guidance

The package should be immediately removed from all affected systems. All secrets and keys stored on compromised machines must be rotated from a separate, trusted device. Due to the severity of the compromise, affected systems should be treated as fully compromised and undergo thorough investigation and remediation beyond package removal.

Summary

The 'nativescript-swisspost-pcc-creative-editor' npm package contains malicious code executed during the 'preinstall' lifecycle event. The package reads the installer's project directory name from the environment variable 'INIT_CWD' and sends this information with a timestamp to a hardcoded external callback URL. This behavior constitutes a dependency-confusion attack, allowing arbitrary code execution at install time and leaking sensitive project information. The package pretends to be an internal Swiss Post package but is malicious. The package version explicitly affected is 54.16.3.
