# XAMPP
## XAMPP on Windows
There is a way to upload a shell to escalate to `nt authority\system`
privileges through xampp. I used this multiple times in the last few days.
Upload a PHP shell like [FOZZ's
p0wny-shell](https://github.com/flozz/p0wny-shell.git) to the `C:\xampp\htdocs`
directory and visit the resource in the browser.
