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
Fields which are in 'read only' state in Bank Statement Draft in Manage Bank Statements application, could be modified by MERGE method. The property of an OData entity representing assumably immutable method is not protected against external modifications leading to integrity violations. Confidentiality and Availability are not impacted.

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

In the Manage Bank Statements application, OData entities representing Bank Statement Drafts contain fields marked as read-only in the UI, but the backend does not enforce immutability for these fields during MERGE requests. An attacker can modify read-only fields (such as document status, amounts, or transaction dates) by sending MERGE HTTP requests directly to the OData endpoint, violating data integrity without requiring authentication bypass since this appears to be an authorization logic flaw rather than an authentication bypass.

MitigationImplement server-side validation to reject MERGE (or PATCH) requests that attempt to modify fields designated as read-only in the Bank Statement Draft entity. Add field-level permission checks in the OData service layer to enforce immutability constraints regardless of the HTTP method used.

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. Verify SAP S/4HANA version
    Execute transaction SM37 or use SAP MII version query to determine the SAP S/4HANA installation version number. Compare against affected versions 102, 103, 104, 105, 106, 107.
    Affected if Installed version matches 102, 103, 104, 105, 106, or 107
  2. Confirm Manage Bank Statements is active
    Check SAP Fiori launchpad or transaction SE11 for the presence of the Manage Bank Statements (F0917A or similar) app. Query the OData service catalog for services containing 'BankStatement' or 'BankStatementDraft' entities.
    Affected if The Manage Bank Statements application or its OData service is deployed and accessible
  3. Identify Bank Statement Draft OData endpoint
    Locate the OData service metadata document ( /$metadata) for the Bank Statement Draft entity. Identify the entity set name and navigation property paths. Common endpoint pattern: /sap/opu/odata/sap/API_BANKSTATEMENTDRAFT_SRV/ or similar.
    Affected if OData service endpoint exists and exposes BankStatementDraft entity set
  4. Check field-level annotations in metadata
    Download and inspect the OData metadata XML. Search for BankStatementDraft entity type and examine Property elements for 'Nullable' and 'sap:updatable' attributes on fields representing status, amounts, or dates.
    Affected if Metadata shows fields as read-only (sap:updatable='false') but no server-side enforcement is configured
  5. Audit logs for MERGE/PATCH requests
    Review SAP Gateway logs (transaction /IWFND/ERROR_LOG or /IWFND/APPL_LOG) and security audit log (transaction SM20) for recent MERGE or PATCH requests targeting BankStatementDraft entity. Filter by URI path containing 'BankStatementDraft' and HTTP method MERGE or PATCH.
    Affected if MERGE or PATCH requests to read-only fields are logged and were accepted by the backend

Environment is affected if SAP S/4HANA version is 102-107, the Manage Bank Statements OData service is active, and MERGE requests to read-only fields on BankStatementDraft entities are processed without validation.

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 data
Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Implement server-side validation to reject MERGE (or PATCH) requests that attempt to modify fields designated as read-only in the Bank Statement Draft entity. Add field-level permission checks in the OData service layer to enforce immutability constraints regardless of the HTTP method used.
