"The version of Unitronics VisiLogic installed on the remote host is prior to 9.9.00. It is, therefore, affected by a
vulnerability.

  - Unitronics VisiLogic before version 9.9.00, used in Vision and Samba PLCs and HMIs, uses a default
    administrative password. An unauthenticated attacker with network access can take administrative control
    of a vulnerable system. (CVE-2023-6448)

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