CubeCart 是一款电子商务软件解决方案。在 6.7.5 版本之前， 文件中的“删除笔记”（delete-note）处理器在从 表中删除记录时，仅验证了 和 参数的存在性，而未检查操作者是否具备订单删除权限（CC_PERM_DELETE）。因此，一名经过身份验证但缺乏订单修改权限的管理员，可以通过直接调用该处理器并传入有效的标识符，删除订单历史笔记，从而移除运营记录和审计跟踪数据。该问题已在 6.7.5 版本中修复。

Vulnerability Title
CubeCart: Missing Authorization Check for Order Note Deletion in orders.index.inc.php
Source: CVE Program / CVE List V5
Vulnerability Description
CubeCart is an ecommerce software solution. Prior to 6.7.5, the delete-note handler in admin/sources/orders.index.inc.php verifies only the presence of order_id and delete-note parameters before deleting records from CubeCart_order_notes, without requiring CC_PERM_DELETE for orders. An authenticated administrator lacking order modification privileges can directly invoke the handler with valid identifiers and delete order-history notes, removing operational records and audit-trail data. This issue is fixed in version 6.7.5.
