The SQL Injection lab on TryHackMe consists of a series of challenges designed to test one's skills in identifying and exploiting SQL injection vulnerabilities. The lab provides a web application with a database backend, and users are tasked with injecting malicious SQL code to extract or modify data.
The second challenge requires us to extract data from the users table. We need to inject a SQL query that will extract the username and password columns.
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.
The first challenge requires us to dump the database using SQL injection. To do this, we need to inject a SQL query that will extract the database schema and contents. We start by analyzing the web application's input fields and identifying potential SQL injection points.
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.
Using SQL injection, we inject the following query: 1' UNION SELECT * FROM products -- . However, we soon realize that we need to escalate privileges to gain write access to the products table.
