You will notice the keyword appearing frequently in search queries. Historically, earlier versions of Security Shepherd (pre-2021) had a relatively straightforward SQLi in Challenge 5. However, the "new" iteration—updated for modern OWASP Top 10 compliance—introduced three critical changes:
This is the most effective defense. It ensures that user input is never interpreted as SQL commands.
When the database executes the query, it interprets the database structure based on how characters are closed or opened. If an attacker submits a raw single quote, the application alters it to \' , neutralizing the quote so that the database treats it as a literal character instead of a string delimiter.

Similar to many challenges in this series, the vulnerable PHP or Java code likely looks something like this: You will notice the keyword appearing frequently in
regardless of the actual coupon, you can use a classic tautology injection. Solution Steps Tautology Injection : Input a payload that always evaluates to true, such as: ' OR 1=1 -- " OR 1=1 -- : By using
Bypass a VIP coupon validation system to retrieve sensitive information or a specific "VIP" coupon code. It ensures that user input is never interpreted
Navigate to . The interface typically presents a search box—often a "Find User" or "Lookup Product ID" field. Let’s simulate the environment:
When a user submits a valid coupon code, the database finds a matching record, the checkout system drops the item total to zero, and the platform delivers the success flag. When a user submits an incorrect coupon, the lookup returns an empty set, prompting the application to output a failure or "Invalid Coupon" warning. Step-by-Step Walkthrough: Bypassing the VIP Check
