Access Control: Missing Authorization Check
Abstract
적절한 권한 검사가 없으면 프로그램이 권한이 없는 사용자에게 제한된 트랜잭션을 시작하도록 허용할 수도 있습니다.
Explanation
사용자가 수동으로 새로운 트랜잭션을 시작할 때마다 SAP 시스템은 해당 사용자가 트랜잭션 실행 권한이 있는지 자동으로 검사합니다. 하지만 사용자가 CALL TRANSACTION 문 호출을 통해 프로그래밍 방식으로 새로운 트랜잭션을 시작하는 경우에는 이러한 검사가 기본으로 수행되지는 않습니다. 이 문 이전에 명시적인 권한 부여 검사가 수행되지 않는다면 ABAP 프로그램을 실행하는 사용자가 허용되지 않아야 할 트랜잭션을 시작할 수 있습니다.
예제 1: 다음 코드는 ABAP 프로그램을 실행하는 트랜잭션을 호출합니다.
이 경우, 코드를 실행하는 사용자가 원래는 권한이 없음에도 ABAP 프로그램을 시작하고 시스템에 대한 전체 제어 권한을 확보할 수도 있습니다.
예제 1: 다음 코드는 ABAP 프로그램을 실행하는 트랜잭션을 호출합니다.
...
CALL TRANSACTION 'SA38'.
...
이 경우, 코드를 실행하는 사용자가 원래는 권한이 없음에도 ABAP 프로그램을 시작하고 시스템에 대한 전체 제어 권한을 확보할 수도 있습니다.
