A TL;DR solution to Security Driven by @terjanq

A TL;DR solution to Security Driven by @terjanq

For this year's Google CTF, I prepared a challenge that is based on a real-world vulnerability. The challenge wasn't solved by any team during the competition so here is the proof that the challenge was in fact solvable! :)

The goal of the challenge was to send a malicious file to the admin and leak their file with a flag. The ID of the file was embedded into the challenge description (/file?id=133711377731) and only admin had access to it, because the file was private.

Disclamer: The write-up is written on airplane therefore the quality of it is poor, mostly to showcase the required steps to solve the challenge

Everything I Know About UI Routing

Definitions

  1. Location - The location of the application. Usually just a URL, but the location can contain multiple pieces of information that can be used by an app
    1. pathname - The "file/directory" portion of the URL, like invoices/123
    2. search - The stuff after ? in a URL like /assignments?showGrades=1.
    3. query - A parsed version of search, usually an object but not a standard browser feature.
    4. hash - The # portion of the URL. This is not available to servers in request.url so its client only. By default it means which part of the page the user should be scrolled to, but developers use it for various things.
    5. state - Object associated with a location. Think of it like a hidden URL query. It's state you want to keep with a specific location, but you don't want it to be visible in the URL.

The Rules of React

The Rules of React

All libraries have subtle rules that you have to follow for them to work well. Often these are implied and undocumented rules that you have to learn as you go. This is an attempt to document the rules of React renders. Ideally a type system could enforce it.

What Functions Are "Pure"?

A number of methods in React are assumed to be "pure".

On classes that's the constructor, getDerivedStateFromProps, shouldComponentUpdate and render.

Google Apps Script to read JSON and write to sheet
function getJSON(aUrl,sheetname) {
