Sql Injection Challenge 5 Security Shepherd !link! May 2026
SQL Injection Challenge 5 in OWASP Security Shepherd involves exploiting a vulnerable coupon code input field to retrieve a VIP code via UNION-based SQL injection. The challenge, which stems from unsanitized user input in a SELECT query, requires injecting payloads like ' UNION SELECT coupon_code FROM coupons WHERE '1'='1
to bypass payment and retrieve the result key. For more details, visit Pentest-Tools.com
OWASP Security Shepherd SQL Injection Challenge 5 is a hands-on exercise designed to teach advanced exploitation techniques by using sub-query injection to bypass input filters and extract a hidden VIP coupon code. The challenge, often featuring a "Troll Shop" scenario, requires using UNION SELECT techniques to map backend table structures and retrieve secure data.

Bypassing Common Filters in Security Shepherd
Challenge 5 is notorious for implementing naïve blacklist filtering. You may encounter blocks on:
- Spaces: Use
/**/or%0a(newline). SELECT/UNION: Use case variation (SeLeCt) or double nesting (UNIunionON).- Quotes: Use hex encoding for string literals.
Example filtered bypass:
1%00%20AND%201=2%00%20UNION%00%20SELECT%00%201,group_concat(username),3%00%20FROM%00%20users SQL Injection Challenge 5 in OWASP Security Shepherd
Part 2: The Vulnerability – Blind SQL Injection Explained
Introduction
In the world of web application security, few names carry as much weight—or as much infamy—as SQL Injection (SQLi). Despite being first discovered over two decades ago, it remains a persistent vulnerability, consistently ranking in the OWASP Top 10. For those looking to move beyond theory and into practical exploitation, the OWASP Security Shepherd project offers a gamified, hands-on training ground.
Among its many gauntlets, SQL Injection Challenge 5 stands as a rite of passage. It is not your grandfather’s simple ' OR 1=1 -- login bypass. This challenge is designed to break novice assumptions, forcing you to think about database architecture, query syntax, and the subtle art of data exfiltration. Spaces: Use /**/ or %0a (newline)
