SQL Injection is a code injection technique that attackers use to exploit vulnerabilities in a web application's database layer. It occurs when untrusted data is sent to an interpreter as part of a command or query, tricking the interpreter into executing unintended commands or accessing unauthorized data.
Attackers can extract sensitive information including user credentials, personal data, and financial records.
Attackers can modify, delete, or insert data in the database, potentially causing data corruption or loss.
SQL injection can be used to bypass authentication mechanisms and gain unauthorized access to systems.
In severe cases, attackers can gain complete control over the database server and underlying system.
Protecting against SQL injection requires a multi-layered security approach:
