"SAP NetWeaver Application Server for Java is affected by denial of service vulnerability:

  - Due to unrestricted access to the Meta Model Repository services in SAP NetWeaver AS Java, attackers can 
    perform DoS attacks on the application, which may prevent legitimate users from accessing it. This can 
    result in no impact on confidentiality and integrity but a high impact on the availability of the 
    application. (CVE-2024-34688)

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