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 .
in the coupon field to force the database to leak a valid VIP code, which is then used to "purchase" the result key for free. Are you having trouble with the mechanism in this specific level, or does the payload work for your version?
The project stands out as an elite training platform designed to teach the fundamentals of web application security through interactive, practical challenges. Within its training paths, the SQL Injection Challenge 5 (commonly encountering themes like the VIP Coupon Code module) represents a significant leap from basic beginner injection mechanics into intermediate application security testing.

This seemingly minor implementation detail creates a powerful vulnerability. A clever attacker can abuse this behavior to create an unescaped single quote by chaining backslashes.
: The field fails to use Prepared Statements , allowing user input to change the query's intent.
Filter blocks single quote. But what if you use double quotes? The filter allows double quotes? Let’s test: input " — validation passes. Double quotes are not in the blocked set. Interesting. The is a classic laboratory exercise designed to
Before we dive into the injection itself, let’s establish context. OWASP Security Shepherd is a web and mobile application security training platform. Unlike vulnerable VMs that require installation, Shepherd is a deliberately flawed application designed to teach secure coding. It features escalating difficulty levels (Modules 1-10), with acting as the bridge between novice "copy-paste" hackers and true manual exploit developers.

This challenge forces you to understand how SQL parsers work versus how input filters work. It’s a game of "Simon Says" with the database. Are you having trouble with the mechanism in
In a default installation of the OWASP Security Shepherd Project, simulates a classic e-commerce business logic flaw. The user is presented with a checkout screen selling "Trolls" or virtual merchandise. To complete the challenge, you must obtain a solution key that is only generated when you process an order with a valid VIP Coupon Code .
Anya smiled. The shepherd’s gate had only just opened. She cracked her knuckles and loaded the next challenge. The real hunt had begun.
