The is a classic laboratory exercise designed to teach web application security by exposing common logical flaws in database input filtering. In this challenge, users face a simulated store checkout page where they must use a SQL Injection (SQLi) vulnerability to bypass the cost of purchasing a "Troll" item by retrieving or overriding a VIP Coupon Code .

The key piece of information is that the application is as a protection against SQL injection. Importantly, it does not change double quotes ( " ) . 1 and 1=2 -> Returns "No user exists" (False)

In SQL syntax, a double backslash ( \\ ) acts as an escaped backslash literal. The first backslash cancels out the second backslash, meaning the database interprets \\ simply as a text backslash character.

Consider a vulnerable login form that builds a SQL query like this:
