"The version of the SAP NetWeaver kernel detected on the remote host is affected by multiple vulnerabilities as
referenced in SAP Security Note 3804858:

  - SAP Web Dispatcher and SAP NetWeaver Application Server ABAP (Internet Communication Manager) do not
    perform sufficient request validation in certain administrative functionality. In the context of
    Application Server ABAP and SAP Web Dispatcher, an unauthenticated attacker could trick a logged-on
    administrator into visiting a malicious link. Visiting the link could cause unintended actions in the
    administrator's session. Successful exploitation could lead to a full compromise of the underlying
    operating system, resulting in a high impact on confidentiality, integrity, and availability.
    (CVE-2026-89119)

  - SAP HANA XSA Web Dispatcher does not perform sufficient request validation in certain administrative
    functionality. In the context of SAP HANA XSA Web Dispatcher, an unauthenticated attacker could trick a
    logged-on administrator into visiting a malicious link. Visiting the link could cause unintended actions in
    the administrator's session. Successful exploitation could lead to a temporary compromise of the SAP HANA
    XSA Web Dispatcher, resulting in a high impact on confidentiality, and partial impact on integrity, and
    availability. (CVE-2026-120014)

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