"The version of SAP NetWeaver AS ABAP detected on the remote host is affected by a cross-site scripting vulnerability as
referenced in SAP Security Note 3754659:

  - Due to a Cross-Site Scripting (XSS) vulnerability, applications based on Business Server Pages framework
    in SAP NetWeaver Application Server ABAP reflects unsanitized input into the HTTP response which allows
    an attacker to inject and execute arbitrary JavaScript code under certain conditions. Successful
    exploitation could allow the attacker to steal session information, perform authenticated actions on
    behalf of the victim user etc. This vulnerability has low impact on confidentiality and integrity of the
    data and no impact on application's availability. (CVE-2026-44760)

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