"The version of SAP NetWeaver AS ABAP detected on the remote host is affected by a privilege escalation vulnerability as
referenced in SAP Security Note 3772411:

  - SAP ABAP Development Tools does not perform necessary authorization checks for certain functionality,
    allowing an attacker with low privileges to execute unauthorized database operations against SAP NetWeaver
    AS ABAP. Successful exploitation could allow the attacker to read sensitive data, modify application data,
    and disrupt access for legitimate users, resulting in high impact on confidentiality, integrity, and
    availability. (CVE-2026-58243)

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