Overview of this book

This is an easy-to-follow guide, full of hands-on and real-world examples of applications. Each of the vulnerabilities discussed in the book is accompanied with the practical approach to the vulnerability, and the underlying security issue. This book is intended for all those who are looking to get started in Android security or Android application penetration testing. You don’t need to be an Android developer to learn from this book, but it is highly recommended that developers have some experience in order to learn how to create secure applications for Android.

Security vulnerability

One of the most common vulnerabilities in both web applications and mobile applications are the injection-based vulnerabilities. SQLite also suffers from an injection vulnerability if the input given by the user is used as it is or with little but insufficient protection in a dynamic SQL query.

Let's have a look at the SQL query used to query the data in the application, as shown here:

String getSQL = "SELECT * FROM " + tableName + " WHERE " + 
username + " = '" + uname + "' AND " + password + " = '" + pword + 
"'";
Cursor cursor = dataBase.rawQuery(getSQL , null);

In the preceding SQL query, the uname and pword fields are being passed from the user input directly into the SQL query, which is then executed using the rawQuery method. The rawQuery method will, in fact, simply execute whatever SQL query is passed to it. Another method that is similar to rawQuery is the execSQL method, which is as vulnerable as rawQuery.

The preceding SQL query is used to verify the user...
