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 · unedited
Due to missing authorization check, SAP NetWeaver Application Server for ABAP - versions 700, 701, 702, 731, allows an authenticated attacker, to access content on the start screen of any transaction that is available with in the same SAP system even if he/she isn't authorized for that transaction. A successful exploitation could expose information and in worst case manipulate data before the start screen is executed, resulting in limited impact on confidentiality and integrity of the application.

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 confidence

SAP NetWeaver ABAP application server lacks proper authorization checks before rendering transaction start screens, allowing any authenticated user to access transaction content they aren't authorized to execute. This broken access control enables information disclosure and potential data manipulation at the start screen before transaction execution completes.

MitigationImplement and enforce authorization checks (e.g., S_TCODE, authority-check) before displaying transaction start screens; apply SAP security patches if available.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify installed SAP NetWeaver ABAP version
    Execute transaction code SM51 or check the SAP system version via SAP GUI: Log in to the ABAP system, enter transaction SM51, and note the Release and Kernel version displayed. Alternatively, use transaction SWI1 or check system profile parameters.
    Affected if The installed version matches 700, 701, 702, or 731 exactly (these are the only affected versions listed).
  2. Review transaction code authorization objects
    Use transaction SUIM (User Information System) or directly query authorization objects. Check if the S_TCODE object is properly configured with restrictive values for non-privileged users.
    Affected if Users have access to transaction codes they should not have permission to execute, indicating S_TCODE restrictions are not enforced.
  3. Test unauthorized transaction access at start screen
    As a low-privileged authenticated user, attempt to call a transaction they are not authorized for (e.g., via URL parameter /n/ transaction code, or by attempting to start the transaction). Observe whether the transaction start screen renders before an authorization check error occurs.
    Affected if The transaction start screen loads and displays content before any authorization check error is thrown, meaning the vulnerability is present.
  4. Verify authority-check implementation in custom transactions
    Review ABAP code for transactions that call authority-check or S_TCODE validation only after the initial screen has rendered. Use transaction SE93 to review transaction properties, or use transaction SLIN for extended program checks.
    Affected if Transactions lack proper authority-check calls before screen rendering, or authorization errors occur only after transaction execution rather than at start screen.

A system is affected if it runs SAP NetWeaver ABAP versions 700, 701, 702, or 731 AND low-privileged authenticated users can view transaction start screens for unauthorized transactions before authorization checks block execution.
