SELECT coupon_code FROM coupons WHERE coupon_code = "" OR 1=1;

Based on community threads for , the three most common failure points are:

OWASP Security Shepherd SQL Injection Challenge 5 (often featuring the "Super Meme Shop"), the objective is to bypass coupon validation to purchase items for free and obtain the result key. Core Vulnerability & Strategy The challenge uses an input field for a Coupon Code . The backend likely executes a query similar to:

The escaping function works by replacing single quote, including those already preceded by backslashes. This means a single quote inserted by the user is always preceded by a backslash, becoming \' . This prevents the single quote from breaking out of its intended string context. sql+injection+challenge+5+security+shepherd+new

The flaw becomes evident when you alter the input to target the escape character itself. Because the code targets every single instance of a quote, it fails to evaluate if a user has already input a backslash character ( \ ) right before that quote.

Submit and intercept the request with a proxy like .

Navigate to . The interface typically presents a search box—often a "Find User" or "Lookup Product ID" field. Let’s simulate the environment: SELECT coupon_code FROM coupons WHERE coupon_code = ""

Forcing users to extract secondary tokens (e.g., a "VIP Coupon Code") from one part of the app and apply it elsewhere to complete the level.

In the realm of cybersecurity education, the project stands as a cornerstone for hands-on learning, transforming abstract vulnerabilities into tangible puzzles. Among its tiered levels, SQL Injection Challenge 5 (often referred to as the "VIP Check" or "Coupon Code" challenge) represents a critical pivot point where basic logic meets more complex database structures. The Objective: Exploiting the "VIP" Shop

// VULNERABLE String query = "SELECT * FROM users WHERE username = '" + username + "'"; // SECURE PreparedStatement pstmt = connection.prepareStatement("SELECT * FROM users WHERE username = ?"); pstmt.setString(1, username); ResultSet results = pstmt.executeQuery(); Use code with caution. 2. Proper Input Escaping/Sanitization This means a single quote inserted by the

Manually escaping characters is a "blacklisting" approach that is highly prone to errors, as seen in this challenge. To prevent such vulnerabilities in real-world applications, follow these industry standards:

Always ensure you are assigned to a "class" within Security Shepherd to see and submit the result keys correctly. path for this specific challenge? OWASP Security Shepherd Project - CSRF 1 (CSRF Challenge)

The techniques used in this challenge are not just theoretical; they reflect real-world vulnerabilities that continue to be discovered in applications today. and has consistently ranked at the top of the OWASP Top 10 list for years.

Here is a step-by-step walkthrough to obtaining the key for this challenge.
