Mitigation and Workarounds

The primary mitigation for CVE-2026-45054 is to upgrade CubeCart to version 6.7.0 or later, which contains the necessary fix. If an immediate upgrade is not possible, consider implementing a Web Application Firewall (WAF) rule to filter potentially malicious SQL fragments in the sort parameter of the admin.php?_g=orders&node=transactions endpoint. Specifically, look for unusual characters or SQL keywords within the sort parameter. Additionally, review and restrict database user permissions to limit the potential impact of a successful SQL Injection attack. After upgrading, confirm the vulnerability is resolved by attempting a SQL Injection payload in the affected endpoint and verifying that it is properly sanitized.

How to fix

Actualice CubeCart a la versión 6.7.0 o posterior para mitigar la vulnerabilidad de inyección SQL. Esta actualización corrige la falta de validación en el parámetro 'sort[]', previniendo la ejecución de código SQL malicioso por parte de administradores autenticados.
