Segurança de software não é o mesmo que software de segurança. Aqui, estamos interessados em tópicos como autenticação, controle de acesso, confidencialidade, criptografia e gestão de privilégios.

Cross-Client Data Access

Abstract
O programa pode permitir que um usuário não autorizado acesse os dados de outro cliente do sistema SAP.
Explanation
Dados de aplicativos no sistema SAP são separados com base em clientes (separação por cliente), e todas as instruções Open SQL acessam/modificam automaticamente os dados pertencentes ao cliente conectado (manipulação por cliente). Isso é fornecido para que os dados pertencentes a diferentes unidades de negócios ou organizações dentro da empresa possam ser logicamente separados. No entanto, é possível esquivar-se dos mecanismos de separação e manipulação por cliente a partir de um programa ABAP usando o seguinte:

1. Instruções Native SQL ou
2. Instruções Open SQL com a adição CLIENT SPECIFIED ou
3. API ADBC (ABAP Database Connectivity) ou
4. Outras APIs que acessam dados específicos do cliente a partir de outros clientes

O SAP não verifica se o usuário está autorizado a acessar os dados do cliente especificado. Isto representa um risco de segurança na medida em que um usuário não autorizado pode visualizar ou modificar dados de um cliente diferente.

Exemplo 1: O código a seguir usa o Open SQL para buscar detalhes de funcionários.


...
PARAMETERS: p_input TYPE sy-mandt.

SELECT *
  FROM employee_records
  CLIENT SPECIFIED
  INTO TABLE tab_output
  WHERE mandt = p_input.
...


Nesse caso, um usuário de outra forma não autorizado que estiver executando o código poderá visualizar os detalhes de outro cliente diferente do cliente SY-MANDT conectado.
