CVE-2019-0257
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 · uneditedCustomizing functionality of SAP NetWeaver AS ABAP Platform (fixed in versions from 7.0 to 7.02, from 7.10 to 7.11, 7.30, 7.31, 7.40, from 7.50 to 7.53, from 7.74 to 7.75) does not perform necessary authorization checks for an authenticated user, resulting in escalation of privileges.
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.
dbcve analysis · high confidenceSAP NetWeaver AS ABAP Platform contains a missing authorization check vulnerability in its customizing functionality. An authenticated user can exploit this to perform actions beyond their intended privilege level, leading to privilege escalation. The vulnerability affects multiple version ranges from 7.0 to 7.75.

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 NetWeaver AS ABAP versionUse SAP transaction code SM51 to display the system version, or check the kernel version via the SAP System ID (SID) properties. Alternatively, use transaction code SXMB_VERS for component versions.Affected if The installed version falls within 7.0-7.02, 7.10-7.11, 7.30, 7.31, 7.40, 7.50-7.53, or 7.74-7.75.
-
Confirm ABAP platform componentVerify that the system is running SAP NetWeaver Application Server ABAP or SAP NetWeaver AS ABAP by checking the system information in transaction code SM51 or via the SAP Foundation entry in the system overview.Affected if The system is running any of the listed SAP NetWeaver AS ABAP variants.
-
Verify access to customizing functionalityDetermine if the affected customizing transactions or functions are accessible by reviewing the user role authorizations. Use transaction code SU53 after a user attempts to access customizing functions to check authorization failures.Affected if Authenticated users have access to customizing transactions without proper role-based restrictions.
-
Review user privilege assignmentsCheck user role assignments in transaction code PFCG to see which roles grant customizing or administrative privileges. Compare assigned roles against the principle of least privilege.Affected if Users are assigned roles that grant broader customizing permissions than their job function requires.
Your environment is affected if you are running SAP NetWeaver AS ABAP within versions 7.0-7.02, 7.10-7.11, 7.30, 7.31, 7.40, 7.50-7.53, or 7.74-7.75 and your users have access to customizing functionality without proper authorization controls.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply the SAP security patches for the affected versions (7.0-7.02, 7.10-7.11, 7.30, 7.31, 7.40, 7.50-7.53, 7.74-7.75). Review user roles and authorization assignments to ensure least-privilege principles are enforced.
