Attacking JSON Application : Pentesting JSON Application

Hello all, Its quite long time i have dosn`t updated my blog. So  here we go.



Today we will see how we can pentest  JSON Web Application.

Note- Some of the methods are taken from third party resources and some are presented as my personal experience.

First What Is JSON According To JSON Website.

JSON (JavaScript Object Notation) is a lightweight data-interchange format. It is easy for humans to read and write. It is easy for machines to parse and generate. It is based on a subset of the JavaScript Programming Language, Standard ECMA-262 3rd Edition - December 1999

"In a lemon language JSON is typically used Javascript to pass the parameter". Like Below HTTP Request.

GET /site/getuserinfo=narendrabhati HTTP/1.1
Host: websecgeeks.com
User-Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:44.0) Gecko/20100101 Firefox/44.0
Content-Type: application/json;

JSON Hijacking

JSON Hijacking

Today we will see that, How we can find the
JSON Hijacking vulnerability. As we know that this works on older browsers, still we should analyse it because this is a miss-understood/less known vulnerability for many security people. I hope you will like it.



What is JSON Hijacking?

JSON Hijacking is similior to CSRF(Cross Site Request Forgery) but there is just a little bit difference, In CSRF you trick the victim/user to do some malicious/unwanted activity but in JSON Hijacking you trick the user to access a crafted link which will read some data form victim account and pass it to attacker.

Who Are Affected To This?

This vulnerability is already fixed in modern browser, Like  as of now if victim is using modern browser it cannot be exploited. But still if any one is using an older browser it can be attacked.

Pentesting Node.js Application : Nodejs Application Security

Pentesting Node.js Application : Nodejs Application Security

Hello folks, Today we will see how we can do Pentesting Of NodeJS Application : Attacking NodeJS Application.

As we know that Javascript is a very common and important language and also a light wight which do our most of task very easily.

But we also know that, Great efficiency comes with great risk. Node JS is a kind of server side programming language derived from JS.

According to Wiki

Node.js is an open-source, cross-platform JavaScript run-time environment for executing JavaScript code server-side. Historically, JavaScript was used primarily for client-side scripting, in which scripts written in JavaScript are embedded in a webpage's HTML, to be run client-side by a JavaScript engine in the user's web browser. Node.js enables JavaScript to be used for server-side scripting, and runs scripts server-side to produce dynamic web page content before the page is sent to the user's web browser. Consequently, Node.js has become one of the foundational elements of the "JavaScript everywhere" paradigm,[4] allowing web application development to unify around a single programming language, rather than rely on a different language for writing server side scripts.

Today we will see some of the vulnerabilities which can be exploited in Node.JS application. We will also take a look on the source code for better understanding.
