CVE-2018-2494
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 · uneditedNecessary authorization checks for an authenticated user, resulting in escalation of privileges, have been fixed in SAP Basis AS ABAP of SAP NetWeaver 700 to 750, from 750 onwards delivered as ABAP Platform.
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 confidenceThis is a privilege escalation vulnerability in SAP Basis AS ABAP (NetWeaver 700-750 and ABAP Platform) where an authenticated user can bypass necessary authorization checks to gain elevated privileges beyond what their account should normally have.

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 SAP NetWeaver/ABAP Platform versionExecute transaction SM51 (Release Notes) or use transaction SAINT to view installed software components. Alternatively, use transaction SAPCMS to check the SAP_BASIS component version.Affected if The installed SAP_BASIS version falls within 7.00-7.02, 7.10-7.30, 7.31, 7.40, or 7.50-7.53.
-
Verify authorization object protectionUse transaction SU53 immediately after a user attempts privileged operations to see which authorization checks failed. Review whether critical authorization objects (such as S_RFC, S_ABAP, or user administration objects) are being bypassed.Affected if Users without elevated roles can successfully execute functions that require authorizations they should not possess.
-
Review user role assignments for anomaliesUse transaction PFCG (Role Maintenance) to examine roles assigned to affected users. Compare assigned roles against expected job functions. Check transaction SUIM (User Information System) for users assigned to roles with sensitive authorizations.Affected if Users possess roles or authorizations that were not explicitly assigned to their accounts.
-
Audit critical authorization profilesUse transaction SU02 to review authorization profiles. Examine whether profiles like SAP_ALL or SAP_NEW are inappropriately assigned. Check transaction PRGN for role generation logs.Affected if Users have elevated profiles (such as SAP_ALL) without proper justification or approval.
Your environment is affected if the SAP NetWeaver/ABAP Platform version is 7.00-7.02, 7.10-7.30, 7.31, 7.40, or 7.50-7.53 AND unauthorized users can bypass authorization checks to gain elevated privileges.
