![]() ![]() ![]() With control of a parameter, the attacker can inject a malicious query, which will be executed by the database. In other words, the attacker must have access to a parameter that they can control, which goes into the SQL statement. Without input sensitization, the user can make the database interpret the user input as a SQL statement instead of as data. ![]() Without checks on the received input, string concatenation becomes the most common mistake that leads to SQL injection vulnerability. To allow for dynamic SQL queries, developers often concatenate user input directly into the SQL statement. Our employee management web application has SQL injection vulnerabilities, which mimic the mistakes frequently made by developers.Īpplications will often need dynamic SQL queries to be able to display content based on different conditions set by the user. Through the malicious SQL statements, attackers can steal information from the victim’s database even worse, they may be able to make changes to the database. SQL injection is a technique through which attackers can execute their own malicious SQL statements generally referred to as a malicious payload. Task 2: Introduction to SQL Injection: Part 1 ![]()
