Lesson 2: The Danger of Verbose True/False States

Any page that behaves differently based on any database condition is an oracle. Login forms that say "Invalid password" vs "User not found" are prime real estate for blind SQLi.

What is Blind SQL Injection?

In classic SQL injection, the attacker sees the result of their query directly (e.g., usernames, passwords, credit cards). In blind SQL injection, the application behaves differently based on whether the injected SQL condition is true or false, but it does not display the actual data.

There are two subtypes:

1. Boolean-based Blind SQLi: Relies on true/false conditions changing the application's response.
2. Time-based Blind SQLi: Relies on the database pausing for a specified time if a condition is true.

Challenge 5 typically focuses on Boolean-based Blind SQLi. Solving Security Shepherd: SQL Injection Challenge 5 Lesson

1. Numeric vs. String Injection

If the parameter is numeric (e.g., id=5), no quotes are needed. However, the conceptual approach remains. If your injection fails, try: Boolean-based Blind SQLi : Relies on true/false conditions
