Web Pentesting Basics Of SQL

Web pentesting, also known as web application penetration testing, is a process of identifying security vulnerabilities in web applications. SQL injection is one of the most common and critical vulnerabilities that a web pentester might come across during an engagement. SQL injection is an attack in which an attacker inserts malicious SQL statements into a web application's input fields, with the intention of gaining unauthorized access to the application's backend database.

Here are some basics of SQL injection:

1. SQL injection attacks can be performed by manipulating input fields such as search boxes, login forms, or any other fields that accept user input.

2. The attacker tries to inject malicious SQL statements into the input fields, which can then be executed by the application's backend database.

3. SQL injection can lead to unauthorized access to sensitive data, such as usernames and passwords, credit card numbers, and other confidential information.

4. SQL injection attacks can be prevented by using prepared statements or parameterized queries, which separate user input from SQL code and prevent malicious SQL statements from being executed.

5. Other preventive measures include input validation, input filtering, and access controls.

6. Tools like SQLMap, Havij, and Burp Suite can be used to automate SQL injection attacks and test web applications for vulnerabilities.

7. It is important to note that performing SQL injection attacks on web applications without prior authorization from the application owner is illegal and can lead to severe consequences.

In summary, SQL injection is a serious web application vulnerability that can lead to the compromise of sensitive data. Web pentesters must understand the basics of SQL injection and use appropriate measures to prevent and detect such attacks.
