CVE-2020-7788

This affects the package ini before 1.3.6. If an attacker submits a malicious INI file to an application that parses it with ini.parse, they will pollute the prototype on the application. This can be exploited further depending on the context.

This affects the package ini before 1.3.6. If an attacker submits a malicious INI file to an application that parses it with ini.parse, they will pollute the prototype on the application. This can be exploited further depending on the context.

Overview

The ini npm package before version 1.3.6 has a Prototype Pollution vulnerability.

If an attacker submits a malicious INI file to an application that parses it with ini.parse, they will pollute the prototype on the application. This can be exploited further depending on the context.

Patches

This has been patched in 1.3.6.

Steps to reproduce

payload.ini

[__proto__]
polluted = "polluted"

poc.js:

var fs = require('fs')
var ini = require('ini')

var parsed = ini.parse(fs.readFileSync('./payload.ini', 'utf-8'))
console.log(parsed)
console.log(parsed.__proto__)
console.log(polluted)

> node poc.js
{}
{ polluted: 'polluted' }
{ polluted: 'polluted' }
polluted

Node.js is a platform built on Chrome's JavaScript runtime for easily building fast, scalable network applications. Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices.

Security Fix(es):

Versions of the npm CLI prior to 6.14.6 are vulnerable to an information exposure vulnerability through log files. The CLI supports URLs like "<protocol>://[<user>[:<password>]@]<hostname>[:<port>][:][/]<path>". The password value is not redacted and is printed to stdout and also to any generated log files.(CVE-2020-15095)

This affects the package y18n before 3.2.2, 4.0.1 and 5.0.5. PoC by po6ix: const y18n = require( y18n )(); y18n.setLocale( proto ); y18n.updateLocale({polluted: true}); console.log(polluted); // true(CVE-2020-7774)

This affects the package npm-user-validate before 1.0.1. The regex that validates user emails took exponentially longer to process long input strings beginning with @ characters.(CVE-2020-7754)

This affects the package ini before 1.3.6. If an attacker submits a malicious INI file to an application that parses it with ini.parse, they will pollute the prototype on the application. This can be exploited further depending on the context.(CVE-2020-7788)

It was discovered that there was an issue in nodejs-ini, where an application could be exploited by a malicious input file. This affects the package ini before 1.3.6. If an attacker submits a malicious INI file to an application that parses it with ini.parse, they will pollute the prototype on the application. This can be exploited further depending on the context (CVE-2020-7788).

Root has patched CVE-2020-7788 in the ini package for Root:npm. Multiple fixed versions available.
