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: ACL Manipulation

Java/JSP

Abstract

應用程式會允許攻擊者操控 AWS S3 儲存貯體或物件上的 Access Control Policy (ACP)。

Explanation

應用程式會允許攻擊者控制授予 AWS S3 儲存貯體或物件的權限。如此將允許攻擊者設定能讓其讀取內容或寫入任意檔案的弱式原則。

範例 1：下列程式碼會使用使用者指定的 Access Control Policy 建立新的儲存貯體。



    String canned_acl = request.getParameter("acl");

    CreateBucketRequest createBucketRequest = CreateBucketRequest.builder()
        .bucket("foo")
        .acl(canned_acl)
        .createBucketConfiguration(CreateBucketConfiguration.builder().locationConstraint(region.id()).build())
        .build();

即使應用程式預期系統會從有限集合中選取 acl 參數，但攻擊者仍可將此參數設為 public-read-write，並授予對儲存貯體的完全匿名存取權。
