What causes injection attacks?
Injections are amongst the oldest and most dangerous attacks aimed at web applications. They can lead to data theft, data loss, loss of data integrity, denial of service, as well as full system compromise. The primary reason for injection vulnerabilities is usually insufficient user input validation.
How does injecting malicious code into your browser work?
You could make so much slick stuff with it! They work by injecting malicious code into your browser (or your system). They exploit some vulnerability to inject the malicious code and cause the malicious code to be injected. The malicious code contains a payload of some sort.

How does SQL injection affect a web application?
These statements control a database server behind a web application. Attackers can use SQL Injection vulnerabilities to bypass application security measures. They can go around authentication and authorization of a web page or web application and retrieve the content of the entire SQL database.
How does an attacker inject data into a website?
The attacker injects data into an application to execute crafted XPath queries. They can use them to access unauthorized data and bypass authentication. It’s easy to test if your website or web application is vulnerable to all the injection attacks listed above.
