"The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple
vulnerabilities as referenced in the 508da89c-78b9-11ed-854f-5404a68ad561 advisory.

  - Traefik is an open source HTTP reverse proxy and load balancer. Versions prior to 2.9.6 are subject to a
    potential vulnerability in Traefik displaying the Authorization header in its debug logs. In certain
    cases, if the log level is set to DEBUG, credentials provided using the Authorization header are displayed
    in the debug logs. Attackers must have access to a users logging system in order for credentials to be
    stolen. This issue has been addressed in version 2.9.6. Users are advised to upgrade. Users unable to
    upgrade may set the log level to `INFO`, `WARN`, or `ERROR`. (CVE-2022-23469)

  - Traefik is an open source HTTP reverse proxy and load balancer. In affected versions there is a potential
    vulnerability in Traefik managing TLS connections. A router configured with a not well-formatted TLSOption
    is exposed with an empty TLSOption. For instance, a route secured using an mTLS connection set with a
    wrong CA file is exposed without verifying the client certificates. Users are advised to upgrade to
    version 2.9.6. Users unable to upgrade should check their logs to detect the error messages and fix your
    TLS options. (CVE-2022-46153)

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