Understanding Code Injection Attacks

The video tutorial explains code injection attacks, focusing on SQL injection. It describes how attackers can insert malicious code into applications, particularly through SQL queries, to manipulate databases. The tutorial highlights the ease of exploiting such vulnerabilities and provides a practical example using a vulnerable application called WebGoat. It emphasizes the importance of implementing proper security checks to prevent unauthorized access and control over database data.

What is a code injection attack?

• An attack where the attacker modifies the source code of the application.

• An attack where the attacker steals data from the application.

• An attack where the attacker injects their own code into the application's input fields.

• An attack where the attacker crashes the application.

Why is it important for application developers to put checks into their code?

• To improve the performance of the application.

• To prevent unnecessary or unwanted data from being injected.

• To reduce the size of the application.

• To make the application more user-friendly.

Which of the following is NOT a type of code injection?

• HTML injection

• CSS injection

• SQL injection

• XML injection

What does SQL stand for?

• Structured Query Language

• Secure Query Language

• Simple Query Language

• Standard Query Language

What is the main purpose of SQL injection?

• To allow an attacker to put their own requests into database queries.

• To crash the database server.

• To inject malicious code into the database.

• To modify the application's user interface.

How can an attacker exploit a SQL injection vulnerability?

• By modifying the application's source code.

• By adding additional code into the input fields of the application.

• By making a user click a malicious link.

• By writing additional software.

What does the SQL query 'SELECT * FROM users WHERE name = 'Professor' OR 1=1' do?

• Selects all users with the name 'Professor'.

• Selects all users where 1 equals 1.

• Selects all information from the users table.

• Selects no information from the users table.

What is the purpose of the WebGoat application?

• To act as a real-world application for businesses.

• To serve as a vulnerable application for learning purposes.

• To demonstrate how to prevent SQL injection.

• To provide a secure application for users.

In the example, what additional code is injected to view all information in the database?

• ' AND '0'='0

• ' OR '1'='1

• ' AND '1'='1

• ' OR '0'='0

What can an attacker do after successfully exploiting a SQL injection vulnerability?

• Only modify data in the database.

• Only delete data in the database.

• Only view data in the database.

• View, delete, or modify all data in the database.
