Who should care

Organizations running Smartshop 1 e-commerce deployments; security teams monitoring for SQL injection attacks; developers maintaining PHP-based e-commerce applications; incident response teams investigating potential data exfiltration from e-commerce platforms

Technical summary

Smartshop 1 contains a SQL injection vulnerability in category.php. The id parameter accepts unsanitized user input, allowing unauthenticated attackers to inject malicious SQL code via GET requests. UNION-based payloads enable extraction of sensitive database information including usernames. The vulnerability requires no authentication and can be exploited remotely with low complexity.

Defensive priority

HIGH

Recommended defensive actions

  • Apply input validation and parameterized queries to the id parameter in category.php
  • Implement prepared statements to prevent SQL injection
  • Review and sanitize all user-supplied input in the application
  • Consider web application firewall rules to detect and block SQL injection attempts
  • Monitor for suspicious GET requests to category.php containing SQL keywords or UNION statements

Evidence notes

SQL injection confirmed via UNION-based attack vector in category.php id parameter. CVSS 4.0 vector indicates network attack vector with low attack complexity, no privileges required, and high confidentiality impact. CWE-89 (Improper Neutralization of Special Elements in SQL Command) identified as the primary weakness.
