In this episode, we look into SQL injection techniques, demonstrating how to exploit vulnerabilities in APIs. We go into the APISEC|CON 2025 CTF and begin exploring different challenges, explaining the methodology behind SQL injections, the importance of understanding database structures, and the implications of these vulnerabilities in real-world applications. The session concludes with a discussion on the potential impact of SQL injection attacks and the importance of securing applications against such threats.

Takeaways

• SQL injection is a critical vulnerability in web applications.
• Understanding the structure of databases is essential for exploitation.
• The use of AND and OR clauses can manipulate SQL queries effectively.
• Error messages can provide valuable information for attackers.
• Retrieving table names is a key step in SQL injection attacks.
• The SQLite master table contains essential schema information.
• Using UNION SELECT can help retrieve data from multiple tables.
• SQL injection can lead to unauthorized access and data breaches.
• Proper input validation is crucial to prevent SQL injection.
• Misconfigured databases can amplify the risks associated with SQL injection.
