[Enhancement] Log4Shell Scan about gvm-docker

[Dexus]

you need to allow the docker run on host network.

ownip = this_host();
targetip = get_host_ip();
rnd_port = rand() % 65535;
payload = "${jndi:ldap://" + ownip + ":" + rnd_port + "/a}";

filter = string( "tcp and dst port ", rnd_port, " and src host ", targetip, " and dst host ", ownip );
res = send_capture( socket:soc, data:payload + '\r\n', timeout:5, pcap_filter:filter );

we are not able to limit the ports here, the only possible option is to run on a own IP with all open ports or you have to run with host network.

macvlan would also do help here.

[Dexus]

1. your container need a fqdn (hostname and domainname)
2. you need to use network mode of host, ipvlan or macvlan
3. if you don't run the 2 point before your openvas creates some errors like cloud not get bpf and will not scan correctly. also you will never receive any incoming tcp/udp dumps, which will the log4j scanner create to match the vulnerability of the network service.
