소프트웨어 보안은 보안 소프트웨어가 아닙니다. 여기서는 인증, 액세스 제어, 기밀성, 암호화, 권한 관리 등의 항목에 대해 설명합니다.

Access Control: Amazon Web Services

Java/JSP

Abstract

적절한 access control 없이 사용자가 제어하는 항목 이름을 가진 SimpleDB 데이터베이스에 접근하면 공격자가 허가 받지 않은 레코드를 볼 수 있습니다.

Explanation

데이터베이스 Access control 오류는 다음 경우에 발생합니다.

1. 신뢰할 수 없는 소스에서 데이터가 프로그램에 입력됩니다.

2. 데이터는 SimpleDB 액세스 요청 시 항목 이름을 지정하는 데 사용됩니다.
예제 1: 다음 코드는 해당 트랜잭션의 날짜에 따라 이름이 지정된 송장의 데이터베이스에서 작동합니다. 프로그램은 먼저 고객을 인증하고 그 이후에 고객이 목록에서 이전의 송장을 선택하게 합니다.


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

Example 1의 코드는 현재 사용자의 송장 목록을 생성하지만 공격자는 이 동작을 무시하고 원하는 송장을 요청할 수 있습니다. 이 예제의 코드가 사용자가 요청한 송장에 접근할 수 있는 권한이 있는지 확인하지 않기 때문에 현재 사용자의 송장이 아닌 송장도 모두 표시합니다.
