Authenticated local-file disclosure via external entity expansion
Published Mar 9, 2020 · Updated Aug 6, 2024
XXE in SAP NetWeaver Application Server allows remote authenticated users to read local files through the nwbc_ext2int endpoint. The endpoint accepts posted XML, resolves a file URI declared as an external entity, and reflects the retrieved contents in the FIELD_VALUE element. The flaw requires an authenticated session and an enabled endpoint; disclosed data is limited to files accessible to the SAP server process.
