Access Control: Missing Authorization Check

ABAP

Abstract

Sin las comprobaciones de autorización adecuadas, el programa puede permitir que un usuario no autorizado inicie una transacción restringida.

Explanation

Cuando un usuario inicia manualmente una nueva transacción, el sistema SAP comprueba automáticamente si el usuario está autorizado para ejecutarla. Sin embargo, estas comprobaciones no se hacen de forma predeterminada cuando un usuario inicia mediante programación una nueva transacción llamando a la instrucción CALL TRANSACTION. Si no se efectúa una comprobación de autorización explícita antes de esta instrucción, el usuario que ejecuta el programa ABAP podrá iniciar una transacción que de otro modo no está permitida.

Ejemplo 1: El código siguiente llama a una transacción que puede ejecutar cualquier programa ABAP.


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

En este caso, un usuario no autorizado que ejecuta el código podrá iniciar cualquier programa ABAP y de esta forma hacerse con el control completo del sistema potencialmente.
