We can see a domain name love.htb and staging.love.htb so let's add this to our /etc/hosts file
PORT 80 (HTTP)
On intercepting the request with burp suite we can see POST parameters
I tried messing with parameters and got the error in sql
Tried to do sqli but didn't work so let's visit staging.love.htb
This seems to load a file using url so let's try to add our php shell
<?php system($_GET['cmd']); ?>
But this didn't work so there was port 5000 open on the machine which we cannot access
So let's try to access this port through that url input field
And we got voter admin's credentials but this won't work there as it needs an id
So I though maybe searching on google for voter system and found the exact same application
https://www.sourcecodester.com/php/12306/voting-system-using-php.html
So we need to navigate to /admin in order to login with credentials
Click on Voters from the dashboard
Add a new voter and for a profile picture add a php file either with GET paramter like I did above or powney shell
And opening this php file we will get an interactive shell
Now generate a msfvenom payload because the file gets deleted because of some script of task running in the background
Now for privilege escalation we can run PowerUp.ps1 script to enumerate for misconfigurations or potential vectors for privesc, import the powershell script and run Invoke-Allchecks
We can see that installation for any program will be installed as SYSTEM
I used this as a reference https://www.hackingarticles.in/windows-privilege-escalation-alwaysinstallelevated/
Now there were tons of articles on how you can abuse so there were many ways you can either use the abuse function you saw by just running Write-UserAddMSI and on running ,it will create a msi program which you can install and it will create a local admin user
Another way was to metasploit's post exploit module use exploit/windows/local/always_install_elevated but I did this exploit manually , I generate a windows 64 bit payload as the noramal one didn't respond
This is will create windows installer file which can install it on the target machine using msiexec. So upload it to the target machine
