"The version of the SAP NetWeaver kernel detected on the remote host is affected by an OS command injection
vulnerability as referenced in SAP Security Note 3792735:

  - SAP NetWeaver Application Server ABAP and ABAP Platform does not perform necessary authorization checks for
    certain internal functionality. An attacker with low privileges could invoke affected functionality to
    execute arbitrary operating system commands on the underlying host. Successful exploitation could impact
    resources beyond the vulnerable component, resulting in a high impact on confidentiality, integrity and
    availability of the system. (CVE-2026-76965)

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