CVE-2021-38178Network attack vector

Authenticated code promotion via missing authorization check

Published Oct 12, 2021 · Updated Aug 4, 2024

Improper authorization in SAP NetWeaver AS ABAP and ABAP Platform allows remote authenticated users to transfer ABAP code into protected systems. The software logistics transfer path accepts code artifacts or content without enforcing the required authorization and quality-gate checks. A malicious authenticated account can therefore move unreviewed code into quality and production, compromising system data and operations.
