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
SAP Fiori App Intercompany Balance Reconciliation allows an attacker with high privileges to upload any file (including script files) without proper file format validation. This has low impact on confidentiality, integrity and availability 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 Fiori App Intercompany Balance Reconciliation lacks proper file format validation on its file upload functionality, allowing authenticated high-privilege users to upload arbitrary file types including executable scripts. This arbitrary file upload vulnerability could enable remote code execution or serve as a vector for further compromise.

MitigationImplement strict allowlist-based file format validation and content-type checking on all file upload endpoints, restricting uploads to expected business document formats only.

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. Confirm SAP Fiori Intercompany Balance Reconciliation app deployment
    Access SAP Fiori Launchpad and search for the Intercompany Balance Reconciliation application, or query SAP system tables (e.g., /UI2/APPSET, /UI2/APPS) for app identification
    Affected if The application is present in the SAP Fiori environment
  2. Identify the file upload endpoint
    Review the application's UI components and network traffic when accessing the upload feature. Check SAP Gateway service definitions for upload-related OData operations
    Affected if File upload functionality exists and is accessible in the app
  3. Check if upload functionality is enabled for high-privilege users
    Review SAP PFCG roles and the app's security configuration to determine which user roles can access the upload feature
    Affected if Authenticated users with elevated privileges can access the upload interface
  4. Inspect file validation configuration
    Examine the backend ABAP handler or SAP Gateway service code that processes file uploads. Check for allowlist-based file type validation, MIME type verification, and content inspection
    Affected if No strict file format validation is implemented, or validation relies only on file extension without content-type checking
  5. Test upload capability with non-business file types
    Using an authenticated high-privilege account, attempt to upload a file with an executable extension (e.g., .jsp, .exe, .sh) through the application's upload endpoint
    Affected if The system accepts and stores files with potentially dangerous extensions without rejection

The environment is affected if the SAP Fiori Intercompany Balance Reconciliation app is deployed with its file upload functionality accessible to authenticated high-privilege users and lacking proper allowlist-based file format validation.
