SQL Injection is the main source of web application critical vulnerabilities found globally in 2023, with 23 percent. This critical security flaw allows attackers to manipulate your database by injecting malicious SQL code, potentially exposing sensitive data or completely compromising your systems.

Is it Easy to Execute an SQL Injection Attack?

Unfortunately, SQL injection attacks are relatively easy to execute, especially against poorly protected applications. These attacks require minimal technical knowledge and can be performed using simple tools available online. The attack’s straightforward nature makes it particularly dangerous:

1. An attacker identifies a vulnerable input field on a website (like a login form or search box)
2. Instead of entering expected information, they insert specially crafted SQL code
3. If the application doesn’t properly validate this input, the malicious code executes directly on the database

What Happens if Your Application is Vulnerable to SQL Injection?

The consequences of a successful SQL injection attack can be devastating for your business:

Data Theft Through SQL Injection

Attackers can extract sensitive information including:

• Customer personal data and financial information
• Authentication credentials and passwords
• Proprietary business data
• Healthcare records or other regulated information

Database Destruction via SQL Injection

With the right SQL commands, attackers can:

• Delete entire databases
• Modify critical information
• Create unauthorised administrator accounts
• Insert malicious content into your websites

According to the OWASP Foundation, SQL injection attacks have been responsible for major data breaches affecting millions of users across banking, healthcare, and e-commerce sectors.

Real-World SQL Injection Impact

The 2017 Equifax breach, which exposed personal data of 147 million people, began with an SQL injection vulnerability. The financial impact exceeded £1.3 billion in remediation costs and settlements.

Can I Protect My Applications Against SQL Injection?

Yes, you can effectively defend against SQL injection attacks by implementing proper security practices:

1. Use Parameterised Queries to Prevent SQL Injection

Parameterised queries (prepared statements) separate SQL code from user input. 

2. Implement ORM Frameworks for SQL Security

Object-Relational Mapping (ORM) frameworks like Hibernate (Java), Entity Framework (.NET), or Eloquent (PHP) automatically handle input sanitisation and help prevent SQL injection.

3. Apply Input Validation Against SQL Attacks

Validate all user inputs before processing:

• Implement strict type checking
• Validate against expected patterns
• Reject suspicious characters and known SQL injection patterns

4. Utilise Stored Procedures for Database Security

Stored procedures execute predefined SQL statements, preventing arbitrary SQL execution and protecting against injection.

5. Apply the Principle of Least Privilege for Database Access

Database accounts used by applications should have minimum necessary permissions:

• Restrict SELECT, INSERT, UPDATE operations to only required tables
• Never run applications with database administrator privileges
• Separate databases for different application components
