The in OWASP Security Shepherd is a "VIP Coupon Code" scenario where you must bypass a payment gate by injecting SQL into the coupon field to retrieve or validate a valid VIP code. 🎯 Objective Goal : Obtain a free "Troll" by applying a VIP coupon code.

SELECT coupon_code FROM coupons WHERE coupon_code = ′User_Input′SELECT coupon_code FROM coupons WHERE coupon_code = prime User_Input prime

SELECT * FROM customers WHERE customerId = "\\' OR 1=1; -- "

Before diving into the challenge, it's helpful to understand the platform. The OWASP Security Shepherd is a flagship project of the Open Web Application Security Project (OWASP). It's a web and mobile application security training platform to help security professionals, developers, and students learn and practice manual penetration testing skills. sql+injection+challenge+5+security+shepherd+new

Before attacking, the attacker must control a DNS server or use a service like:

You realize that ( \ ) are not filtered. In MySQL, a backslash escapes the following character. But here, you don’t need quotes if you can inject without them.

Ah — there’s a client-side or server-side filter. You check the page source: The in OWASP Security Shepherd is a "VIP

The application query structure for this specific input validation check behaves as follows: SELECT * FROM customers WHERE customerId = "$DATA"; Use code with caution.

The ingenuity of this challenge lies in exploiting the escaping mechanism's own logic. The solution requires deep thinking about how the escape function processes characters.

The injection occurs in a less common part of the SQL query. The OWASP Security Shepherd is a flagship project

The -- sequence comments out the rest of the query, effectively bypassing the password check.

You recall that LIKE clauses can use wildcards: % (any characters) and _ (single character). The filter allows % and _ because they’re not letters/digits/spaces.

Ensure the database user account used by the web app has the minimum permissions necessary.

is designed to test an attacker's ability to move beyond basic, "in-your-face" injection vulnerabilities. It requires understanding more complex filtering, different query structures, or blind techniques.

A successful SQL injection exploit can have catastrophic consequences:
