CVE-2023-28761Network attack vector

Unauthenticated settings and data access via open API

Published Apr 11, 2023 · Updated Feb 7, 2025

Missing authentication in SAP NetWeaver Enterprise Portal 7.50 allows remote attackers to read or modify server settings and data through an open API. An open interface exposes a service through an API without enforcing authentication; SAP has not disclosed the interface, API, service, or failing code path. Network reachability to that interface is sufficient, and the documented impact is limited to confidentiality and integrity.
