CVE-2022-0686 (opens in a new tab)How to fix?
Upgrade url-parse to version 1.5.8 or higher.
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:/'
}
