CVE-2021-21487
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 · uneditedSAP Payment Engine version 500, 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 · moderate confidenceSAP Payment Engine version 500 contains a missing authorization check vulnerability that allows authenticated users to perform actions beyond their intended privileges, resulting in privilege escalation.
Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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 Payment Engine versionUse SAP transaction code SM37 or check system information to determine the installed SAP Payment Engine version. Look for component version information related to the Payment Engine module.Affected if The installed version is exactly 500 (version 500)
-
Verify authenticated user access existsCheck if user accounts exist in the SAP system that have access to the Payment Engine functionality. Use transaction code SU01 to review user assignments or check if Payment Engine roles are assigned.Affected if There are authenticated users with access to the SAP Payment Engine module
-
Review Payment Engine authorization rolesUse transaction code PFCG to examine the authorization roles assigned to users for the Payment Engine. Check if role assignments allow access to privileged operations beyond the user's intended scope.Affected if Users have roles that grant access to Payment Engine functions beyond their assigned privileges
-
Audit user privilege assignmentsUse transaction code SUIM or direct role analysis to compare actual user privileges against expected baseline permissions for their assigned business roles.Affected if Users possess privileges that exceed what their assigned role should provide (privilege escalation detected)
-
Check for unauthorized action execution logsReview SAP system logs (transaction code SLG1) and audit logs for Payment Engine operations performed by users whose role assignments should not permit such actions.Affected if Audit logs show users executing Payment Engine actions outside their authorized scope
A user is affected if SAP Payment Engine version 500 is installed AND authenticated users have the ability to perform privileged actions beyond their assigned role permissions due to missing authorization checks.
