SAP security note 2024315, “User-driven dynamic procedure calls vulnerability in C-CEE add-on”, is a program error note released on 14.10.2014. Below are the symptom and SAP recommended solution.

Description

Symptom

C-CEE add-on contains user-driven dynamic procedure calls that permit the execution of arbitrary program code of the user’s choice. An attacker can therefore control the behavior of the system or potentially escalate privileges by executing malicious code without having their own legitimate credentials.

An attacker can be authenticated to affected reports without having their own legitimate credentials or may escalate privileges.

Solution

Solution details are provided in the SAP Security Note. Please refer to the official documentation for detailed remediation steps.

• Inject and run their own code
• Obtain additional information that should not be displayed
• Modify data, delete data
• Modify the output of the system
