CVE-2020-26832 Missing Authorization check in SAP NetWeaver AS ABAP and SAP S4 HANA (SAP Landscape Transformation), SAP security note 2993132

Description

UPDATE 13th April 2021: This note has been re-released with updated ‘Correction instruction’ information.

UPDATE 26th January 2021: This note has been re-released with updated ‘Correction instruction’ information.

SAP Landscape Transformation allows a high privileged user to execute a RFC function module to which access should be restricted. This weakness gives attacker ability to read some sensitive internal information and also make vulnerable SAP systems completely unavailable.
