Wget SUDO old version

[RadamireZ]

the option --use-askpass doesn't work anymore in the newer version of wget

we can use a solution described here:
https://exploit-notes.hdks.org/exploit/linux/privilege-escalation/sudo/sudo-wget-privilege-escalation/#4.-transfer-the-content-of-the-shadow-file

that is still present in wget make use of file upload and file download sections

If there is instead a better option that do not waste shadow files should be great

Still works in 1.21.2 (the one in Ubuntu 22.04) and with the latest (1.21.4). The link you provided just shows how to download something, and we already have it.
