About SQL Injection
SQL Injection is a web security vulnerability that allows attackers to interfere with database queries made by an application. This can lead to:
- Unauthorized Access: Bypassing authentication and accessing restricted data
- Data Theft: Extracting sensitive information from the database
- Data Manipulation: Modifying or deleting database contents
- Privilege Escalation: Gaining administrative access to the system
Prevention Techniques
- Use parameterized queries or prepared statements
- Implement proper input validation
- Use an ORM (Object-Relational Mapping) framework
- Apply the principle of least privilege
- Regular security audits and testing
Note: This is an educational demonstration. In real applications, always use parameterized queries and never construct SQL queries by concatenating user input.
