"The version of the SAP NetWeaver kernel detected on the remote host is affected by multiple vulnerabilities as
referenced in SAP Security Note 3769130:

  - Due to improper RFC protocol validation in the SAP Kernel used by the Application Server ABAP of SAP
    NetWeaver and ABAP Platform, an unauthenticated attacker can send a crafted RFC request that exploits
    logical errors in memory management, leading to memory corruption. This could lead to a high impact on
    confidentiality and integrity with low impact on availability of the application. (CVE-2026-76966)

  - SAP NetWeaver Application Server ABAP and ABAP Platform does not properly initialize memory in certain
    internal components. Under certain condition, an attacker with low privileges could disclose uninitialized
    memory contents under specific conditions. This results in a low impact on confidentiality. There is no
    impact on integrity and availability. (CVE-2026-109796)

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