CVE-2020-6188
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedVAT Pro-Rata reports in SAP ERP (SAP_APPL versions 600, 602, 603, 604, 605, 606, 616 and SAP_FIN versions 617, 618, 700, 720, 730) and SAP S/4 HANA (versions 100, 101, 102, 103, 104) do not perform necessary authorization checks for an authenticated user leading to Missing Authorization Check.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify installed SAP product and versionUse transaction code 'SM51' to view the SAP system version, or check system information via 'SID$'. For SAP S/4HANA, verify the version number (e.g., 1511, 1610, 1709, 1809, 1909). For SAP ERP, verify if it is version 6.0.Affected if The installed version is SAP ERP 6.0, or SAP S/4HANA versions 1511, 1610, 1709, 1809, or 1909.
-
Confirm VAT Pro-Rata reports exist in the systemSearch for VAT Pro-Rata related reports using transaction code 'SE38' or 'SA38' with keywords like 'PRO-RATA' or 'VAT PRORATA'. Check if any report programs with these terms are present in the system.Affected if VAT Pro-Rata report programs exist in the system and are accessible to users.
-
Check user access to VAT Pro-Rata reportsUse transaction code 'SUIM' (User Information System) to search for users who have profiles or roles containing access to VAT Pro-Rata reports. Alternatively, check transaction code 'PFCG' for role definitions.Affected if Users without proper authorization can access or execute VAT Pro-Rata reports.
-
Verify authorization objects for VAT Pro-Rata reportsUse transaction code 'SU53' immediately after a user attempts to access VAT Pro-Rata reports to check which authorization objects failed. Also review role assignments via 'PFCG' to see if proper authorization objects (such as F_TAXREP) are configured.Affected if Users can access the reports without the required authorization object checks passing, or no specific authorization objects are assigned to restrict access.
The environment is affected if it runs SAP ERP 6.0 or SAP S/4HANA versions 1511 through 1909, and users can access VAT Pro-Rata reports without proper authorization role restrictions.
