first...we scan the IP machine with nmap 
nmap -sV -sC <IP adress> 
when nmap scan the IP we can know the service and versions 
80/tcp open  http    PHP cli server 5.5 or later (PHP 8.1.0-dev)
so now lits go to the web and check it manuwally.. 
we notice the inspector in the network  the Respond is close! 
and the service of the PHP is old! 
we can search about the vrsion of PHP 8.1.0 dev is old and vulnerabl RCE {remote code execution}
okay we found the vulnerablity that caused the server to be unrespond!
so now  lets fix it ...we can take vulnerability and save in folder with python {Exploit.py} to exploit it
