Simple Banking System CVE-2025-11357

Immediate action should focus on input validation and parameterized queries: upgrade or patch Simple Banking System if a patched version is available from code-astro, or implement immediate compensating controls by validating the Name parameter against a strict whitelist (alphanumeric and allowed special characters only) before it reaches database logic, and refactor the /createuser.php file to use prepared statements with parameterized queries instead of string concatenation for all SQL operations. If immediate patching is not possible, implement database-level restrictions by creating a dedicated low-privilege database user for the application with only INSERT and SELECT permissions on necessary tables, preventing unauthorized data modification or exfiltration. Additionally, enforce strict authentication controls and restrict access to /createuser.php to authorized administrators only via IP whitelisting or role-based access controls. Monitor database activity for suspicious SQL patterns in query logs. Verify fixes with vendor documentation at https://code-projects.org/ and test patches in non-production environments before deployment. The trade-off of database privilege restriction is reduced application functionality if the system requires broader operations, requiring careful review of legitimate application needs.
