Description

Due to a missing authorization check in SAP ERP and SAP S/4HANA (Private Cloud and On-Premise), an authenticated attacker could execute a particular ABAP report to overwrite any existing eight?character executable ABAP report without authorization. If the overwritten report is subsequently executed, the intended functionality could become unavailable. Successful exploitation impacts availability, with a limited impact on integrity confined to the affected report, while confidentiality remains unaffected.
