What type of attack involves injecting commands through a web application?

1. SQL Injection

2. XSS Injection

3. Command Injection

4. All of the above

The correct answer is: All of the above

The type of attack that involves injecting commands through a web application can encompass several different methods, all of which are designed to exploit vulnerabilities in web applications. SQL Injection is a specific type of attack where malicious SQL statements are inserted into an entry field for execution, allowing attackers to manipulate databases and gain unauthorized access to data. XSS (Cross-Site Scripting) Injection, on the other hand, involves injecting malicious scripts into content that users will view, which can lead to session hijacking or redirecting users to malicious sites. Command Injection is a broader form of injection attack that involves inserting arbitrary commands into a system through a web application, which can allow an attacker to execute commands on the server where the application is hosted. Since SQL Injection, XSS Injection, and Command Injection all represent forms of command injection in web applications, their inclusion in the answer demonstrates a comprehensive understanding that there are various methods through which commands can be injected into web applications to exploit vulnerabilities. Therefore, the answer that includes all these types is accurate, highlighting that multiple forms of injection attacks are possible.
