CVE-2019-20500D-Link access point — configuration save reaches the shell

The save-configuration function in the web interface of this D-Link access point passes its parameters to a shell, so a logged-in administrator runs commands on the device itself. Exploit code is public.

YOUR NEXT MOVE

Apply the D-Link firmware fix, and change the administrator password while you are there — an account on the device is the only precondition this has.
