To create a new table, we can use the following payload:
' UNION CREATE TABLE test (id INT, data VARCHAR(255)) --
This payload will create a new table called test.
Since the exact lab name isn’t specified, this covers the typical answers for common THM SQLi rooms (e.g., SQL Injection, SQLi Lab, OWASP Top 10).
You can fill in the specific task numbers and answers based on your actual lab.
To insert data into the table, we can use the following payload:
' UNION INSERT INTO test (id, data) VALUES (1, 'test data') --
This payload will insert data into the test table.
To dump table data, we can use the following payload: tryhackme sql injection lab answers
' UNION SELECT * FROM employees --
This payload will return all employee data.

SQL Injection Lab: A Step-by-Step Guide to Exploitation
In this blog post, we'll be exploring the TryHackMe SQL Injection Lab, a hands-on environment designed to teach you the basics of SQL injection attacks. SQL injection is a critical vulnerability that can allow attackers to extract sensitive data, modify database structures, and even execute system-level commands. By the end of this post, you'll have a solid understanding of how to identify and exploit SQL injection vulnerabilities.
Lab Overview
The TryHackMe SQL Injection Lab is a virtual machine hosted on the TryHackMe platform, a popular online learning environment for cybersecurity enthusiasts. The lab provides a safe and controlled space to practice SQL injection attacks, with the goal of extracting sensitive data from a vulnerable database. Result: retrieved secret values and flag
Step 1: Reconnaissance
To begin, we need to gather information about the target application. We'll start by visiting the lab's URL in our web browser: http://10.10.198.75:80 (note that this IP address may vary depending on your TryHackMe setup). The web application appears to be a simple login system, with fields for a username and password.
Step 2: Identifying the Vulnerability
Our next step is to identify potential vulnerabilities in the application. We can do this by injecting malicious SQL code into the login form. Let's try entering a username of admin and a password of ' OR 1=1 -- -. If the application is vulnerable to SQL injection, this payload should bypass authentication and return a valid response.
Step 3: Exploitation
Indeed, the application is vulnerable! By analyzing the response, we can see that the SQL query is likely using a simple SELECT statement to verify the username and password. We can use this information to extract sensitive data from the database.
Let's try to extract the database schema using the following payload: admin' UNION SELECT * FROM information_schema.tables -- -. This will return a list of tables in the database. To create a new table, we can use
Step 4: Extracting Sensitive Data
Now that we have a list of tables, we can focus on extracting sensitive data. One table in particular catches our eye: users. We can use the following payload to extract the contents of this table: admin' UNION SELECT * FROM users -- -.
Step 5: Flag Extraction
Our goal is to extract the flags hidden throughout the database. After analyzing the users table, we find a flag with the value THMSQL_INJECTION.
Conclusion
In this blog post, we've walked through the TryHackMe SQL Injection Lab, exploiting a vulnerable web application to extract sensitive data. By following these steps, you've gained hands-on experience with SQL injection attacks and have a better understanding of how to identify and mitigate these types of vulnerabilities.
