界: Encapsulation

封裝是要劃定清楚的界限。在網頁瀏覽器中，這可能意味著確保您的行動程式碼不會被其他行動程式碼濫用。在伺服器上，這可能意味著區分經過驗證的資料與未經驗證的資料、區分一個使用者的資料與另一個使用者的資料，或區分允許使用者查看的資料與不允許查看的資料。

Insecure Storage: S3 Write ACP Anonymous Access

Java/JSP

Abstract

應用程式會授予匿名寫入 AWS S3 儲存貯體或物件 Access Control Policy (ACP) 的權限。

Explanation

若授予匿名寫入儲存貯體或物件 Access Control Policy (ACP) 的權限，將會允許攻擊者在該儲存貯體中讀取或寫入任何內容。

範例 1：下列程式碼會設定 Access Control Policy，從而授予對 foo 儲存貯體的匿名寫入 ACP 存取權。


    GetBucketAclRequest bucketAclReq = GetBucketAclRequest.builder().bucket("foo").build();
    GetBucketAclResponse getAclRes = s3.getBucketAcl(bucketAclReq);
    List<Grant> grants = getAclRes.grants();

    Grantee allusers = Grantee.builder().uri("http://acs.amazonaws.com/groups/global/AllUsers").build();
    Permission fc_permission = Permission.fromValue("WRITE_ACP");
    Grant grant = Grant.builder().grantee(allusers).permission(fc_permission).build();
    grants.add(grant);

    AccessControlPolicy acl = AccessControlPolicy.builder().grants(grants).build();
