Injection Attacks

Injection attacks are a type of security vulnerability that allows an attacker to inject malicious code into a web application. This can be done by exploiting a flaw in the application's input validation process, which allows the attacker to submit specially crafted input that includes malicious code. The malicious code can then be executed by the application, giving the attacker access to the application's data and resources.

**Types of Injection Attacks**

There are several different types of injection attacks, including:

• SQL injection attacks target database-driven web applications. The attacker injects SQL statements into the application's input, which are then executed by the database. This can allow the attacker to access sensitive data, modify data, or even delete data.
• XSS (cross-site scripting) attacks target web applications that allow users to input data that is displayed to other users. The attacker injects malicious JavaScript code into the application's input, which is then executed by the browser of the user who views the tainted data. This can allow the attacker to steal cookies, session IDs, or other sensitive information from the user's browser.
• Command injection attacks target web applications that allow users to execute commands on the server. The attacker injects malicious commands into the application's input, which are then executed by the server. This can allow the attacker to gain access to the server's files and resources, or even to execute arbitrary code on the server.
