Realizamos un ping a la máquina objetivo para verificar la conectividad y obtener información sobre la ruta utilizando la opción -R para incluir la ruta de retorno:
El valor de TTL (Time To Live) igual a 127 puede ser indicativo de que el sistema operativo de la máquina objetivo es Windows. El TTL es un valor en el campo de los paquetes IP que indica la duración que un paquete puede estar en una red antes de ser descartado. Windows establece por defecto el valor de TTL de sus paquetes IP en 128, que al pasar por un salto en la red se decrementa a 127.
Escaneo de puertos con Nmap
Luego, realizamos un escaneo de puertos utilizando Nmap para identificar los puertos abiertos en la máquina objetivo. Utilizamos las opciones -p- para escanear todos los puertos, --open para mostrar solo los puertos abiertos, -sS para un escaneo de tipo TCP SYN, --min-rate 5000 para establecer la velocidad mínima de paquetes y -vvv para un nivel de verbosidad alto. Además, utilizamos -n para desactivar la resolución de DNS, -Pn para no realizar el escaneo de ping, y -oG allPorts para guardar la salida en un archivo con formato Greppable para luego utilizar nuestra función extractPorts:
Escaneo detallado con Nmap
Posteriormente, realizamos un escaneo más detallado de los puertos identificados utilizando la opción -sCV para detección de versiones y scripts de enumeración de servicios. Específicamente, indicamos los puertos a escanear con -p __PORTS__ (reemplazando __PORTS__ con los puertos identificados en el paso anterior) y guardamos la salida en un archivo de texto con el nombre targeted:
Ahora lo que suelo hacer es enviarle el outpout a ChatGPT para que me explique a qué me estoy enfrentando.
Lo que más me interesa es sobre el Openfire Jabber, cursiosamente se llama como la máquina. Así que necesitaré un cliente para ello utilizaré
Utilizaré Pidgin, por lo que lo instalo en mi máquina Kali:
Modificando /etc/hosts
Para añadir la entrada "10.129.187.106 pov.htb" al archivo /etc/hosts, puedes usar el siguiente comando en la terminal:

¡Vaya escaneo exhaustivo, 3KY! Este reporte de Nmap es oro puro para perfilar y determinar los próximos pasos en una evaluación de ciberseguridad ofensiva. Veamos algunos aspectos clave:
Observaciones Iniciales
Microsoft Windows Active Directory: La presencia de puertos como 53 (DNS), 88 (Kerberos), 389 y 636 (LDAP), 3268 y 3269 (Global Catalog) sugiere fuertemente que estamos lidiando con un controlador de dominio de Active Directory. Esto es crucial porque significa que cualquier vulnerabilidad aquí podría tener un impacto significativo en toda la red.
Openfire: Los puertos 5222, 5223, 5262, 5263, 5269, 5270, 5275, y 5276 indican la presencia de un servidor Openfire, una popular plataforma de mensajería instantánea que utiliza XMPP. La presencia de múltiples puertos sugiere que tanto las versiones cifradas como las no cifradas del servicio están en funcionamiento.
Versiones y Configuraciones Específicas: La versión específica de Openfire (3.10.0 o posterior) y las configuraciones de Microsoft Windows y Active Directory brindan un punto de partida para buscar vulnerabilidades conocidas y exploits potenciales.
Ángulos de Ataque y Consideraciones
Enumeración de AD: Podrías aprovechar herramientas como ldapsearch para extraer información valiosa de los servicios LDAP expuestos. Esto podría incluir enumeración de usuarios, grupos y relaciones de confianza que podrían ser explotadas.
Explotación de Kerberos: El puerto 88 abierto es un candidato para ataques como Kerberoasting, permitiendo extraer hashes de cuentas de servicio para intentar crackearlos offline.
Fuzzing y Explotación de Openfire: Dada la presencia de un servidor Openfire, sería interesante buscar exploits específicos para la versión detectada. Además, podría valer la pena realizar fuzzing contra los servicios XMPP para descubrir vulnerabilidades desconocidas o mal manejo de entradas.
