## Description

Due to a missing authentication check in the SAP NetWeaver application on IBM i-series, the application allows high privileged unauthorized users to read, modify, or delete sensitive information, as well as access administrative or privileged functionalities. This results in a high impact on the confidentiality, integrity, and availability of the application.

## What to do
