vulnerability as referenced in SAP Security Note 3752864:

  - SAP NetWeaver and ABAP Platform (Change and Transport System - Customer Transport Integration Wizard)
    allows a low-privileged user to modify configuration tables that control access to data objects during
    specific operations. These unauthorized modifications could result in processing delays and operational
    disruption, leading to a low impact on the integrity and availability of the application with no impact on
    confidentiality. (CVE-2026-58241)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
