What is SQL?
A computer language called SQL (Structured Query Language) was created specifically for managing and modifying relational databases. Databases, tables, and the data contained in those tables can all be created, modified, and deleted using it. SQL is a popular language for managing data because it offers a standard syntax and commands that can be used with various database systems, including MySQL, Oracle, Microsoft SQL Server, and PostgreSQL. SQL can be utilized for many different tasks, including data selection and filtering, table joining, index creation, and more. It is a crucial tool for database administrators, developers, and data analysts.
What is SQL Injection Attack?
So basically SQL injection attack is the manipulation of the SQL queries that are executing on the backend side. It typically enables an attacker to examine data that they would not typically be able to retrieve. Data belonging to other users or any other data that the application itself has access to may fall under this category. In many instances, an attacker can update or remove this data, permanently altering the application’s content or behavior.
what actions might a successful attacker take against a compromised target?
If the website is vulnerable to SQL Injection then the attacker can perform a lot of acting directly on the database.
:- Unauthorized Access to sensitive data Like usernames, Passwords, Creditcard numbers, etc.
:- The attacker can make a persistent backdoor for a long period of time
:- An attacker can modify or delete data in the database, potentially causing significant damage to the website or the organization that hosts it. For example, they could change the prices of products in an online store or delete customer orders.
:- In the case of a SQL injection attack, a successful attacker may gain access to the database server and pivot to other systems that are connected to it. For example, the database server may be connected to a web server that hosts the website, an application server that handles user requests, or a file server that stores data files.
:- Execute arbitrary commands on the database server, allowing them to take complete control of the server.
