Title
Information Disclosure vulnerability in SAP Human Capital Management for SAP S/4HANA
Summary
During authorization checks in SAP Human Capital Management for SAP S/4HANA, the system returns specific messages. Due to this, an authenticated user with low privileges could guess and enumerate the content shown, beyond their authorized scope. This leads to disclosure of sensitive information causing a high impact on confidentiality, while integrity and availability are unaffected.
