CVE-2023-24527Network attack vector

Unauthenticated data access via open directory API

Published Apr 11, 2023 · Updated Feb 7, 2025

Missing authentication in SAP NetWeaver AS Java Deploy Service 7.50 allows remote attackers to read server settings and data. The service accepts unauthenticated connections on an open interface and exposes a naming and directory API without identity checks. Network reachability to that interface is sufficient; disclosed impact is read-only, with no modification or service interruption.
