Mastering Modern Web Penetration Testing

By: Prakhar Prasad, Rafay Baloch

Overview of this book

Web penetration testing is a growing, fast-moving, and absolutely critical field in information security. This book executes modern web application attacks and utilises cutting-edge hacking techniques with an enhanced knowledge of web application security. We will cover web hacking techniques so you can explore the attack vectors during penetration tests. The book encompasses the latest technologies such as OAuth 2.0, Web API testing methodologies and XML vectors used by hackers. Some lesser discussed attack vectors such as RPO (relative path overwrite), DOM clobbering, PHP Object Injection and etc. has been covered in this book. We'll explain various old school techniques in depth such as XSS, CSRF, SQL Injection through the ever-dependable SQLMap and reconnaissance. Websites nowadays provide APIs to allow integration with third party applications, thereby exposing a lot of attack surface, we cover testing of these APIs using real-life examples. This pragmatic guide will be a great benefit and will help you prepare fully secure applications.

Dumping the data – in an error-based scenario


Let's go back to the previously discussed example, and now we shall exploit the vulnerability using the error-based technique of SQLMap to list the database user and list of databases as follows:

./sqlmap.py -u http://192.168.50.2/Less-1/?id=2 --current-user

The output is shown in the following screenshot:

Impressive! The current database user pointed out by SQLMap is root.

Now let us print the list of databases present using --dbs switch as follows:

./sqlmap.py -u http://192.168.50.2/Less-1/?id=2 --dbs

The output is shown in the following screenshot:

Once we have the list of databases available, it may be a good idea to dump one of them. For demonstration, I'll select security and dump out the tables present inside it. SQLMap provides the --tables switch to list the same, but it must be used in parallel with the -D switch, which tells it which database to choose, while dumping the tables as follows:

./sqlmap.py --technique=E -u http://192.168.50...
