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: Azure

Abstract
使用攻擊者控制的值,在沒有適當存取控制的情況下存取 Azure Queue/Blob 可讓攻擊者檢視/修改/刪除未經授權的佇列/Blob 及其訊息/內容。
Explanation
在下列情況下會發生 Azure 雲端存取控制錯誤:

1. 資料從一個不可信賴的來源進入程式。


2. 資料用於檢視/修改/刪除未經授權的佇列/Blob 及其訊息/內容。
範例 1:以下程式碼會刪除指定的佇列及其訊息。


...
var queueName = queryStringData['name'];
var queueSvc;
queueSvc = azureStorage.createQueueService();
...
queueSvc.deleteQueue(queueName, option, function(error, response){
if(!error){
// all the messages has been deleted
}
});
...
範例 2:以下程式碼會刪除指定的 Blob 容器及其內容。


...
var containerName = queryStringData['name'];
var blobSvc;
blobSvc = azureStorage.createBlobService();
...
blobSvc.deleteContainer(containerName, function (error, response) {
if (!error) {
// all the content in the given container has been deleted
}
});
...


儘管 Example 1Example 2 中的程式碼會刪除指定的佇列/Blob 容器及其屬於目前使用者/程式的訊息/內容,但攻擊者可以刪除該 Azure 帳戶的任何佇列/Blob。因為此範例中的程式碼不會進行檢查以確保使用者/程式具備清除所要求佇列/Blob 的權限,因此即使其不屬於目前的使用者/程式,程式碼也會清除佇列/Blob。
