CVE-2021-27609

Authenticated activation manipulation via unchecked oData authorization

Published Apr 13, 2021 · Updated Aug 3, 2024

Missing authorization in SAP Focused Run 200 and 300 allows remote authenticated users to change EarlyWatch Alert activation via oData. The EarlyWatch Alert activation oData service accepts activation changes without enforcing the intended authorization check. A valid account is required, and exploitation changes whether service data is collected and sent to SAP, without reported data disclosure.
