Playing with GraphQL when introspection is disabled

Quick write up on extracting a GraphQL schema when introspection is disabled. Bits and pieces sourced from various sources. Successfully tested on an Apollo instance.

TLDR: Some GraphQL instances provide name autocomplete suggestions. Some peeps have written tools to automate the extraction process. (ref https://youtu.be/nPB8o0cSnvM).

1. Bruteforce schema without introspection

First step is using a tool called clairvoyance by @nikitastupin (https://github.com/nikitastupin/clairvoyance). I found the main repo to lack error handling and support for additional features such as proxy.

index.phps listing below

<?php
session_start();

$link = @mysql_connect('localhost', '', '');

@mysql_select_db('', $link);

The documentation is so limited. A compilation of things I found on StackOverflow and don't want to have to search it up again.

Bypass root check

MS-MSDT 0-day Office RCE

MS Office docx files may contain external OLE Object references as HTML files. There is an HTML sceme "ms-msdt:" which invokes the msdt diagnostic tool, what is capable of executing arbitrary code (specified in parameters).

The result is a terrifying attack vector for getting RCE through opening malicious docx files (without using macros).

Here are the steps to build a Proof-of-Concept docx:

1. Open Word (used up-to-date 2019 Pro, 16.0.10386.20017), create a dummy document, insert an (OLE) object (as a Bitmap Image), save it in docx.
