SQL Injections: Web Application Vulnerabilities and Methods of Attacking Databases via SQL Queries
SQL injections are one of the most common and dangerous vulnerabilities in web applications that can lead to serious consequences for data security. What is SQL Injection? SQL injection is a type of attack on web applications in which an attacker injects malicious SQL code into input fields or query parameters, allowing them to perform unwanted operations on the database. SQL injections occur due to insufficient server-side processing of user input. SQL injection works by inserting SQL code into a query string, which is then executed by the database. This SQL can be intentionally designed to modify or retrieve data from a database, bypass authorization, delete or modify tables, and more.
