affected by a local privilege escalation vulnerability as referenced in the HPESBNW05012 advisory.

- A local privilege-escalation vulnerability has been discovered in the HPE Aruba Networking ClearPass OnGuard
  Software for Linux. Successful exploitation of this vulnerability could allow a local attacker to achieve
  arbitrary code execution with root privileges. (CVE-2026-23599)

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