"The version of bluez installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected
by a vulnerability as referenced in the CVE-2023-45866 advisory.

  - Bluetooth HID Hosts in BlueZ May permit an unauthenticated Peripheral role HID Device to initiate and
    establish an encrypted connection, and accept HID keyboard reports, potentially permitting injection of
    HID messages when no user interaction has occurred in the Central role to authorize such access. An
    example affected package is bluez 5.64-0ubuntu1 in Ubuntu 22.04LTS. NOTE: in some cases, a CVE-2020-0556
    mitigation would have already addressed this Bluetooth HID Hosts issue. (CVE-2023-45866)

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