CubeCart is an ecommerce software solution. Prior to 6.7.0, an Authenticated Server-Side Template Injection (SSTI) vulnerability exists in multiple modules of CubeCart (including Email Templates, Invoices, Documents, and Contact Forms).

This allows any authenticated user with administrative privileges to execute arbitrary operating system commands (RCE) on the server. This vulnerability is fixed in 6.7.0.
