Access Control: Missing Authorization Check

ABAP

Abstract

如果不执行适当的授权检查，未经授权的用户就可以利用该程序启动受限制的事务。

Explanation

只要用户手动启动新事务，SAP 系统就会自动检查用户是否有权执行此事务。但是，当用户通过调用 CALL TRANSACTION 语句以编程方式启动新事务时，默认情况下不会执行这些检查。如果在此语句前未明确执行授权检查，运行 ABAP 程序的用户将能够启动原本不允许的事务。

例 1：以下代码会调用可执行任何 ABAP 程序的事务。


...
CALL TRANSACTION 'SA38'.
...

在这种情况下，运行此代码的非授权用户将能够启动任何 ABAP 程序，进而可能彻底控制系统。
