Developers need to sanitize the input section and remove the potentially malicious code in SQL statements that could allow attackers to gain unauthorized access to sensitive database information: usernames, passwords, and other essential credentials. To prevent this from happening, you should avoid using the user input directly in the application code. This is an example of a URL with a modified query that will generate an error and let a malicious hacker gain access to all the usernames and passwords.

In the below example, an SQL command has been inserted to change the value of the fields Username ($username = 1' or '1' = '1) and Password ($password = 1' or '1' = '1) which will be modified as follows: It involves using classic HTTP requests by inserting unexpected commands through a user interface to cause the database server to respond with an error that includes information about the target: structure, version, or operating system. One of the most common types of SQL injection techniques is error-based SQL injection which is the simplest SQL exploit and easy to detect. Here is a sample URL which extracts the type and version of the database server (MySQL) by exploiting the SQL Injection vulnerability: ' UNION SELECT NULL, NULL, - '

Execute operating system commands on the database server (under certain conditions).

Read/write files from the disk (under certain conditions).

Read/write information from the database.

The input provided by an attacker may include characters that could interfere with the SQL syntax and will result in arbitrary SQL queries performed on the database.Īs a result, the risk of an SQL Injection vulnerability is that the attacker could:

They do this by first finding a vulnerable user input within a web app and create input content which is often used as the malicious payload to launch this attack. SQLi is also one of the most well-known web application vulnerabilities with a dedicated chapter in the OWASP Top 10 project and is also a highly chased after vulnerability in bug bounty programs.Ī common SQL injection attack happens when attackers try to insert malicious SQL statements located in an HTTP (or HTTPS) request by changing the current behavior of SQL statements created by the web application.

SQL Injection remains one of the most prevalent attacks used by hackers and a serious security threat to both individuals and companies. What is an SQL injection and how do I prevent this attack?
