The fourth challenge requires us to dump the database using advanced SQL injection techniques. We need to inject a SQL query that will extract the database schema and contents using advanced techniques.

The database schema consists of two tables: users and products .

SQL injection is a critical web application security vulnerability that can have severe consequences if left unaddressed. TryHackMe's SQL Injection lab provides a valuable learning experience for individuals to practice and learn about SQL injection attacks. By completing the lab's challenges, individuals can gain hands-on experience in identifying and exploiting SQL injection vulnerabilities, as well as learn how to prevent and mitigate such attacks.

Using SQL injection, we inject the following query: 1' UNION SELECT * FROM users -- . This query will extract the username and password columns from the users table.

We can escalate privileges by injecting the following query: 1' UNION SELECT 'admin', 'admin', 'admin' INTO users -- . This query will create a new user with admin privileges.
