Tryhackme Sql Injection Lab - Answers

: What is the acronym for the software used to manage databases? Answer : DBMS (Database Management System) Task 3: What is SQL Injection?

The TryHackMe SQL Injection lab is a virtual lab that provides a vulnerable web application for you to practice exploiting SQL injection vulnerabilities. The lab is designed to simulate a real-world scenario, where you will have to use SQL injection techniques to extract sensitive data from a database.

This is the most effective defense. It ensures that the database treats user input strictly as data, never as executable code.

Once you know the column count, determine which columns reflect data back to the screen. Inject: ' UNION SELECT 1,2,3 -- - Step 3: Extract Database Information : What is the database name found in the UNION lab? tryhackme sql injection lab answers

Next, determine which of these columns display data on the screen by injecting a UNION SELECT statement filled with dummy data or numbers. ' UNION SELECT 1, 2, 3-- - Use code with caution.

UNION-based SQLi allows an attacker to append the results of their own query to the results of the original application query. Step 1: Find the number of columns

Now, swap out the valid string column with database metadata functions.

Now, replace the visible column numbers with database functions to map the system. ' UNION SELECT 1, database(), 3-- - Get Database Version: ' UNION SELECT 1, version(), 3-- - Step 4: Enumerate Table Names : What is the acronym for the software

The application returns different content depending on whether the query evaluates to TRUE or FALSE.

Direct concatenation of user input into queries. This demonstrates the most basic form of vulnerability where simple logic can alter query outcomes.

' (Single quote): Often used to "break" a query to test for vulnerabilities. ; (Semicolon): Signifies the end of a SQL statement.

Once you discover an interesting table name (e.g., users or flags ), list its columns: The lab is designed to simulate a real-world

' UNION SELECT NULL, table_name, NULL FROM information_schema.tables WHERE table_schema=database()-- - Use code with caution.

Because '1'='1' is always true, the database returns the record for the admin user, successfully authenticating the session.

The goal of this challenge is to log into the application as an administrator without knowing the password. Methodology

After balancing the columns, use a payload like 0 UNION SELECT 1,2,database(); to find the database name and eventually the flag. Blind SQL Injection (Boolean & Time-Based)
