CVE-2023-29108Network attack vector

Backend access via erroneous IP netmask handling

Published Apr 11, 2023 · Updated Feb 12, 2025

IP-filter bypass in SAP ABAP Platform and SAP Web Dispatcher allows remote authenticated users to access backend applications. The IP filter handles network masks incorrectly, allowing source addresses outside the intended restrictions to reach protected backends. Low-privileged access is required under SAP's assessment, and the reported consequence is unauthorized backend access without integrity or availability impact.
