"The version of SAP NetWeaver Application Server Java detected on the remote host is affected by a reflected cross-site
scripting vulnerability as referenced in SAP Security Note 3723655:

  - Due to a reflected cross-site scripting (XSS) vulnerability in SAP NetWeaver JAVA (JDBC Test Servlet),
    an unauthenticated attacker could craft a URL that embeds a malicious script. If a victim clicks this
    link, the injected input is processed during web page generation, resulting in the execution of
    malicious content in the victim's browser. This could allow the attacker to access and/or modify
    information related to the webclient, impacting the confidentiality and integrity of the application,
    with no impact to availability. (CVE-2026-44746)

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