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 24375796-7cbc-11ef-a3a9-001cc0382b2f advisory.

    OpenPrinting reports:
    Due to the service binding to *:631 ( INADDR_ANY ), multiple bugs                 in cups-browsed can be exploited in sequence to introduce a                 malicious printer to the system. This chain of exploits ultimately                 enables an attacker to execute arbitrary commands remotely on the                 target machine without authentication when a print job is started.
                Posing a significant security risk over the network. Notably, this                 vulnerability is particularly concerning as it can be exploited                 from the public internet, potentially exposing a vast number of                 systems to remote attacks if their CUPS services are enabled.
    The vulnerability allows an attacker on the internet to create a               new printer device with arbitrary commands in the PPD file of the               printer. Attacks using mDNS on the local network can also replace an               existing printer. The commands are executed when a user attempts to               print on the malicious device. They run with the privileges of the               user cups.
    It is recommended to disable the cups_browsed service until patches               become available. On FreeBSD this is the default. You can check the               status and disable the service with the following commands:
    # service cups_browsed status               # service cups_browsed stop               # service cups_browsed disable     If you choose to leave the service enabled, attacks from the               internet can be blocked by removing the cups protocol from the               BrowseRemoteProtocols and BrowseProtocols directives in               /usr/local/etc/cups/cups-browsed.conf. Attacks using mDNS can be               blocked by removing the dnssd protocol as well. Access can be               limited to specific IP addresses using BrowseAllow, BrowseDeny, and               BrowseOrder directives as documented in cups-browsed.conf(5). Then               restart the service with the following command:
    # service cups_browsed restart

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