Immediate actions: (1) Patch/Update: Check code-projects project repository or vendor advisories for patched versions beyond 1.0 (likelihood low if abandoned); if unavailable, perform in-house remediation; (2) Input Validation: Implement strict email format validation using regex or built-in validators, rejecting inputs containing SQL metacharacters; (3) Parameterized Queries: Replace all string concatenation in SQL queries with prepared statements/parameterized queries for the email parameter and all user inputs; (4) Escape Special Characters: If parameterized queries are unavailable, apply database-specific escaping functions (e.g., mysqli_real_escape_string for MySQL); (5) WAF/IPS: Deploy Web Application Firewall rules to detect and block SQL injection patterns in login requests (signatures targeting UNION, SELECT, OR 1=1, etc.); (6) Database Permissions: Apply principle of least privilege—limit login.php database user account to SELECT-only on authentication tables, preventing INSERT/UPDATE/DELETE exploitation; (7) Monitoring: Implement logging and alerting on unusual SQL query patterns or authentication failures; (8) Consider Migration: Evaluate migration to a maintained alternative if code-projects Mobile Shop is no longer actively supported. No official vendor patches are currently available in references.
