SAP security note 2155978, "Potential disclosure of persisted data in Greek FI localization", released on 05.08.2015. Below are the symptom and SAP recommended solution.

Description

Symptom

An attacker can use specially crafted inputs to modify database commands, resulting in the retrieval of additional information persisted by the system.

Solution

As a general rule, SAP recommends that you install a solution by applying a Support Package. However, if you need to install a solution earlier, use the Note Assistant to implement the correction instruction.

Reason and prerequisites

The problem is caused by an SQL injection vulnerability. The code composes an SQL statement that contains strings that can be altered by an attacker. The manipulated SQL statement can then be used to retrieve data from the database.
