Sensitive file disclosure via external entity resolution

Published Mar 14, 2023 · Updated Feb 27, 2025

XML external entity injection in SAP NetWeaver Enterprise Portal 7.50 allows remote authenticated users to read sensitive files and data. The portal's XML parser resolves external entity references in a crafted XML file, allowing referenced data to be returned without modification. Access requires an authenticated user with sufficient privileges to reach the parser, and the reported consequence is read-only disclosure.
