Attack that inserts malicious SQL code into application queries to access or manipulate databases.
SQL injection (SQLi) exploits vulnerabilities in web applications that incorporate user input into database queries without proper validation. Attackers insert SQL commands through input fields, URLs, or other data entry points. Successful SQLi can read sensitive data, modify or delete database contents, execute administrative operations, or even access the underlying server. SQL injection has been a top web vulnerability for decades and remains prevalent due to insecure coding practices.
Why It Matters
The DSC Perspective:
SQL injection can expose your entire database—customer data, credentials, financial records. Web applications handling sensitive data need security testing to identify SQL injection vulnerabilities. WAF provides additional protection.
