What does SQL Injection primarily target?

• A. Web servers
• B. Network infrastructure
• C. Vulnerable applications to inject malicious SQL queries
• D. User credentials

Answer: (C)

SQL Injection primarily targets vulnerable applications by exploiting weaknesses in their database interaction. When an application fails to properly validate and sanitize user inputs, an attacker can manipulate the SQL queries that the application sends to the database. This allows the attacker to inject malicious SQL code, which can lead to unauthorized data access, data manipulation, or even complete control of the database. In this context, the focus is on the application layer, where the attacker can gain access to sensitive information by crafting SQL statements that the application executes without sufficient input validation. By understanding the structure of the database and the way the application interacts with it, attackers can construct queries that may allow them to retrieve, modify, or delete data. This emphasis on applications rather than infrastructure or user credentials highlights the specific vulnerability that SQL Injection exploits: the interaction between user inputs and database queries within applications. Protecting against SQL Injection requires developers to implement security measures, such as prepared statements and parameterized queries, to sanitize user inputs effectively.
