в‘пёЏ HTML injection (of 38 bytes) Bypassing Content Security Policy We now finally have arbitrary HTML injection! Rules array items along with the smuggled 38 bytes of HTML payload!

The code at 'init' uses innerHTML to inject the It is possible to use the JSONP endpoint again, this time to execute the 'init()' The first real step of the challenge was to 'plant' HTML code into a globally defined array named ' rules'.В This could be achieved using the native Array.push function: I've described the impact of executing multiple methods using SOME and how it can be as bad or nearly as bad as XSS throughout the SOME white-paper.

Abusing the JSONP endpoint with designated callbackВ parameter by navigating each window context.

Setting up 5-6 windows (iframes) based on the amount of methods we want to execute on the challenge page.Multiple Method Execution is all about constructing a gadget and reusing existing code. This however will only execute an alert, which will not allow stealing the CSP nonce or executing arbitrary XSS.

Injecting '%26callback=alert' to the client_id parameter allows us to overwrite the 'connect.php' endpoint's callback parameter and therefore get control over the method to execute. в‘пёЏ Method execution can quite simply be controlled by abusing HPP. Method Execution via HTTP Parameter Pollution Shafigullin ( terjanq ( Luan Herrera ( Dive The first to solve was the great, followed by 3 other fantastic players: Roman Thankfully 4 of the players were above all others and solved this challenge relatively fast! All with the intended solution, though some used shorter and cleaner code to solve. Here is a simplified version of the solution: ('Error: ''>'','406: Not Acceptable')

Navigating the DOM tree to overcome character limits.Дuring my talk in 2017, I already published the instructions for solving steps 1-2 andД«efore we dig into the details the following is the challenge solution:.

Bypass CSP to execute XSS while abusing 'strict-dynamic'.

Inject arbitrary HTML limited to 38 characters.

Abuse the lack of X-Frame-Options to obtain multiple method execution.

Control the method execution using a callback (SOME attack).

To solve the challenge one had to complete several steps: His callback challenge was similar and inspired me to share my research in the form of a my own XSS challenge. I created a new XSS challenge! Can you solve it? ( slide 16, under 'What are the vulnerable endpoints?')ДЄs I was always 'too busy', on Jun 7, 2020, released the following tweet: 'JSONP is NOT vulnerable without a chain' While the vulnerable, active content-types like 'text/html', 'Adobe Flash' or 'ActiveX plugins' are less common.Дuring HackInTheBox 2017, I shared the hint of my ongoing research: Nowadays, finding vulnerable callback endpoints got harder as passive content-types dominate the web.

This talk explains how to abuse callback endpoints to execute javascript methods in a vulnerable domain. Want to execute XSS? But, there's always this 'text/javascript' (or similar) When you see a callback control in a JSONP endpoint doesn't that make you
