界: Security Features

軟體安全性並非安全性軟體。我們關注驗證、Access Control、保密性、加密以及權限管理之類的主題。

Access Control: Amazon Web Services

Java/JSP

Abstract

利用使用者控制的項目名稱存取 SimpleDB 資料庫且沒有適當的 Access Control 時，會讓攻擊者檢視未經授權的記錄。

Explanation

在以下情況會發生資料庫存取控制錯誤：

1. 資料從一個不可信賴的來源進入程式。

2. 資料用來指定 SimpleDB 存取呼叫中的項目名稱。
範例 1：以下程式碼在清單資料庫上運作，清單則以交易日期作為命名方式。程式會先驗證客戶，接著讓客戶從先前的清單中進行選擇。


...
String selectedInvoice = request.getParameter("invoiceDate");
...
AmazonSimpleDBClient sdbc = new AmazonSimpleDBClient(appAWSCredentials);
GetAttributesResult sdbResult = sdbc.getAttributes(new GetAttributesRequest("invoices", selectedInvoice));
...

雖然 Example 1 中的程式碼產生屬於目前使用者的清單，但攻擊者可能略過此行為來要求任何想要的清單。因為此範例中的程式碼沒有檢查以確保使用者擁有存取所要求清單的權限，所以即使清單不屬於目前使用者，程式碼也會顯示所有清單。
