Sql Injection Challenge 5 Security Shepherd !link! Site

OWASP Security Shepherd's SQL Injection Challenge 5, or "VIP Coupon Check," demonstrates how unsanitized input concatenated directly into database queries creates critical SQL injection vulnerabilities. Attackers can bypass input validation using ' OR '1'='1 or utilize UNION SELECT statements to extract hidden data from the backend. For a detailed walkthrough of this specific challenge, visit this Numerade article. SqlInjection5VipCheck.java - GitHub
