Background
element-plus-vite-cli is a command-line interface tool designed for building applications using Vue 3 and Element Plus. It streamlines the development process by providing essential functionalities for project setup and management. However, recent findings have revealed that this package is susceptible to a significant security vulnerability that allows for the execution of malicious code, potentially compromising user systems.
Vulnerability Detail
The vulnerability originates from the package invoking tooling-bootstrap.cjs, which searches for specific sentinel files characteristic of fintech applications. Upon finding a match, it concatenates and decodes embedded base64 chunks into a malicious MJS agent. This agent is then executed, allowing attackers to perform various operations such as executing arbitrary commands, exfiltrating files, and manipulating system processes. The agent communicates with a command-and-control server, posing severe risks to user data and system integrity.
How To Fix
This package is malicious. Remove it and rotate any credentials it could have accessed.
npm uninstall element-plus-vite-cliIf it arrived as a transitive dependency, remove the package that pulled it in, then reinstall.
