DBO Privileges

May 29, 2004

I have just noticed something very discomforting.

I was told that a user with DBO privileges is able to alter their own database. A conversation of course began to where I was in disagreement with him. The ultimate test of course would be setup the scenario. To my surpise he was right!

I checked the BOL documentation and my concerns were verified.

I have checked permissions on the user I created as well as on a user that previously exists on the MSSQL Server. Only DBO permissions were given to the tested users.

I thought maybe this had something to do with the autogrow setting which is a setting we would enable on a dedicated MSSQL Server but not on a shared MSSQL Server. I toggled this option and the DBO was still able to make size changes to their database.

This is very upsetting as we charge for additional reserved database space. Aside from that, we wouldn't want to have a user with unlimited resources to the server. I could easily fill up a hard drive if I were to update the autogrow setting of the database as DBO and run an infinite loop that would insert data into tables.

I then tested the ability for a user to restore a backup and to my surprise it worked without error for the DBO only privileged user. The DBO user was also able to restore previously dated databases assuming that they knew the file name which would not be hard to guess since it is appended with a date stamp (My_Database_20042905.BAK).

Why is this? Is there a way to correct this and prevent the DBO user to only have access to their database but not the above mentioned type privileges?

User Privileges Ms Sql

Feb 21, 2008

 Basically to defend against SQL injection I want to be able to stop basic users or admins from being able to drop tables or doing other damaging activities. I'm using ms sql express, how can I do this? A friend mentioned that he uses MySql and user privileges can be set up in this way.

Table Privileges

Jun 26, 2001

Is there a way to alias a table such that a particular user with privileges on that table (created by another user - not 'dbo') does not have to qualify it with the owner name? I am seeking a database level solution. Thanks.

Execute Privileges On Sp

Jan 12, 2006

Hi. I'm trying to test something on a test db I have installed on my pc, but I am unable to process as I'm doing it. So, basically what I want is to give execute privilege on a procedure to a user, so the user can execute this procedure without having the privileges explicity granted on it (what this procedure do is to truncate a table on which the user has no access). As I've read, SQL Server stored procedures privileges runs with the definers permissions, not the one that is actually executing the procedure. So, what I'm doing is this: in query analyzer, logged in as sa, I did

use test

create table t ( a integer )

create procedure can_truncate as
truncate table t

sp_addlogin 'jmartinez',''

sp_grantdbaccess 'jmartinez','jmartinez'

grant execute on can_truncate to jmartinez

Then I went to connect again, as jmartinez and did:

exec can_truncate

and I get

Server: Msg 3704, Level 16, State 1, Procedure can_truncate, Line 2
User does not have permission to perform this operation on table 't'.

So, I wonder what more permissions would user jmartinez need in order to execute this procedure successfully. I hope you all understand what I am trying to achieve.

Thanks!

Which Of The Two Or More Users' Privileges?

Feb 5, 2007

I am very new to the SQL database. I have the following query. I would appreciate if someone could clarify this for me:

I have created two users (user1 & user2) under the same login name test1 in SQL Server 2005 Database. Further I used the login name (test1) & password (******) of SQL Server in connection string to connect to database.

Now I want to know that how & where can I refer the user name (user1 or user2) to use its previliges.

How will I know that which user's privileges level is used in the connection.?

DTSRUN Privileges?

May 4, 2006

I am trying to get a DTS package to be run from the command line withthe dtsrun utility. The DTS package is stored in the database. The userI supply is a user in the database. I get an error stating "SQL Serverdoes not exist or access denied." It looks to me like the SQL Serverinstance does exist because it tries to start the package. I get"DTSRun: Executing". If I put in a server that is non-existent, I do notget that message. I also know that my username and password are correct.Here is output from my attempt to run dtsrun for my DTS pkg (server,user, password change to protect my db security):C:>dtsrun /Sserver_name /Uuser /Ppass /Npkg_nameDTSRun: Loading...DTSRun: Executing...DTSRun OnStart: DTSStep_DTSExecuteSQLTask_1DTSRun OnError: DTSStep_DTSExecuteSQLTask_1, Error = -2147467259 (80004005)Error string: [DBNETLIB][ConnectionOpen (Connect()).]SQL Serverdoes not exist or access denied.Error source: Microsoft OLE DB Provider for SQL ServerHelp file:Help context: 0Error Detail Records:Error: -2147467259 (80004005); Provider Error: 17 (11)Error string: [DBNETLIB][ConnectionOpen (Connect()).]SQL Serverdoes not exist or access denied.Error source: Microsoft OLE DB Provider for SQL ServerHelp file:Help context: 0DTSRun OnFinish: DTSStep_DTSExecuteSQLTask_1DTSRun: Package execution complete.I suspect that my user I am connecting to the database with does nothave privileges to execute the DTS package.

Issues With Privileges

Aug 11, 2006

I am having trouble with providing the minimum security to a user. After issuing the following:

GRANT EXECUTE ON SCHEMA :: DBO TO skillsnetuser;

I test the permissions with

exec as login = 'skillsnetuser'

exec prcElmtList 1, 1, 102268

revert;

and receive this message

Msg 229, Level 14, State 5, Line 2

SELECT permission denied on object 'Org', database 'SNAccess_Dev', schema 'dbo'.

The principal that owns the dbo schema is dbo and is the principle for all procedures and tables in that schema.

What can I do to shed some light on what is causing this access problem?

Granting Privileges With A Script

Sep 14, 2005

Hi,

I'm trying to write a script to grant privileges to a user (we are trying to allow Windows Authentication in our application).

Previously, we used the following syntax:

grant select, insert, delete, update on area to mattuser

Where mattuser is a valid sql server user.

However, we want to do something like the following:

grant select, insert, delete, update on area to MATT2000IUSR_MATT2000

Where IUSR_MATT2000 is a valid user on computer MATT2000.

We get an error when we try to run this script as follows:

Incorrect syntax near ''

How do we grant permissions for this user, other than doing it manually?

Regards.

Matt.

How To Pass The Privileges From One User To Another?

May 22, 2008



hi,

Grant select on viewSecure to Andrew
go
Exec as login='Andrew'
Select * from viewSecure

Exec as login='Jerry'
Select * from viewSecure
go
but, I received the error 'SELECT permission denied on object 'Customer', database 'AdventureWorks', schema 'Sales'.
Meanwhile, I re-granted Select Privilege to Andrew, I got the same error.
I know Alter Authorization command means to change the owner of an object. I got 3 questions need your help.
1. An user owned an object, if he may have no any privileges to this object?
2.Why I got the same error after re-granted Select privilege to Andrew?
3.How to pass privileges from one user to another?

Thanks a lot.

Retrieving User/Role Privileges - How ?

Jul 7, 2004

Hi,

I need to read and subsequently modify the privileges (rights) of a certain SQL Server user / role from within a Visual Basic Program.

Modifying seems to be easy using standard statements like GRANT/REVOKE. But what about reading all the rights a user has ?

I have researched SQL-DMO, but didn't find what I'm looking for.

Any idea ?

Inserting Records With Limited Privileges

Jul 23, 2005

I am trying to insert records via ASP, with a user that has only writeaccess to the table (db_datawriter, db_denydatareader).That way, if the server is ever compromised, the access informationstored in the source code's connection string will not allow anybody toactually read the database.The problem is that I would like to use ADO methods to insert the data(to prevent SQL injections), but I can't seem to get the rightconnection. It works in plain SQL, but I'd rather not use it.My current code looks like this:connection="Provider=SQLOLEDB.1;User ID=DBwriter;Password=XXX;DataSource=MYSERVER;Initial Catalog=MYDB;"set conn=server.createobject("ADODB.Connection")conn.mode=2 ' adModeWriteconn.open connectionSet rs = Server.CreateObject ("ADODB.Recordset")rs.Open "MYTABLE", conn, adOpenKeySet, adLockPessimistic, adCmdTablers.AddNewrs.Fields("testfield") = "TESTDATA"rs.UpdateAnd the error I get is:Microsoft OLE DB Provider for SQL Server (0x80040E09)SELECT permission denied on object 'MYTABLE', database 'MYDB', owner'dbo'.(If I use a User with read privileges in the connection stringeverything works fine.)

SQLServer And SQL ServerAgent Account Privileges

Jun 15, 2007

After installing SQL Server 2005, a security scan was performed on the SQL server. Below are a few items that the scan identified within the Windows User Rights Assignment as potential vulnerabilities; it is worthy to note in Microsoft's defense that we lock things down pretty tightly in our IT shop. I suspect the SQL Server install assigns these OS privileges to the SQLServer and SQLServerAgent accounts by default. I have not heard of the 1st, 3rd and 4th below and suspect that they are not essential to the normal operation of SQL Server, but would like to know if anyone out there knows for sure. We are considering eliminating some or all of these privieleges for the SQLServer and SQLServerAgent system accounts at the OS level.



1) SQLServer and SQLServerAgent accounts have "Bypass Traverse Setting" privilege within Windows User Rights Assignment

2) SQLServer and SQLServerAgent accounts have "Log on as Batch Job" privilege within Windows User Rights Assignment. I realize I need this to schedule SQL Server jobs which run batch jobs and such, but any other reason to keep this privilege.

3) SQLServer and SQLServerAgent accounts have "Memory Quota" privilege within Windows User Rights Assignment

4) SQLServer and SQLServerAgent accounts have "Replace Process Token" privilege within Windows User Rights Assignment



Any guidance on this would be greatly appreciated.



Regards,



Jason

Run SP From Remote Computer Needs Db_owner Privileges ?

Oct 13, 2006

Hi All,

I created SP and enabled db_datareader and db_datawriter for roles for BUILTINUsers on database level.

I can call that SP from my application if I am accessing DB from my app running on the same machine. If I run app on other machine SP throw exception related to lack of permission.

I fixed that by enabling db_owner roles for BUILTINUsers. But it is not good fix from security point of view.

My question is: is there any other way to allow regular user to run that SP by not giving him db_owner privileges?

Also I have to mention that my SP procedure has some dynamic SQL code.

I would greatly appreciate any help,

Thanks,
Roman

SQLServer And SQLServerAgent Account Privileges

Jun 13, 2007

I recently installed SQL Server 2005 and setup a database for one of the systems that I support as a DBA. After installation and the system, which has remote developers, was tested successfully, our security group performed a security scan on the SQL server. The scan revealed a few potential vulnerabilities. Below are the questionable items that the scan identified within the Windows User Rights Assignment. I believe the SQL Server installation assigns these system privileges to the SQLServer and SQLServerAgent accounts by default. I'd like to know how many, if any of these privileges, are necessary.



1) SQLServer and SQLServerAgent accounts have "Bypass Traverse Setting" privilege within Windows User Rights Assignment

2) SQLServer and SQLServerAgent accounts have "Log on as Batch Job" privilege within Windows User Rights Assignment. I realize I need this to schedule SQL Server jobs which run batch jobs and such, but any other reason to keep this privilege.

3) SQLServer and SQLServerAgent accounts have "Memory Quota" privilege within Windows User Rights Assignment

4) SQLServer and SQLServerAgent accounts have "Replace Process Token" privilege within Windows User Rights Assignment



Any guidance on this would be greatly appreciated.

Querying ALTER TRACE Privileges

Jul 20, 2007

Is there a query that will determine the presence or absence of the ALTER TRACE privilege for the current user?



Also, a note to development. Why is it necessary to have ALTER trace permission to get a read only record set of a) what traces are running and B) the event history of each trace. To ALTER is to change, to SELECT is to view! A separate SELECT TRACE permission would be both useful and intuitive.

SQL Server 2008 :: Using Groups To Manage Privileges

Mar 7, 2015

I am still fairly new to Sql Server 2008 R2 (express) , but am enjoying exploring it.

I have several databases up and running and now a large number of users in each.

But I notice whenever I write a stored procedure I have to go in and add each user to give them permission to exec it. When the user numbers are low its not a problem but I now have over 20 users on 1 database and its becoming tiresome.

I have heard of Active Directory on Windows Server but my database is installed on windows xp professional PC. Its running well and we don't have a budget to change it.

I've been searching the internet to see if there is some way I can create a group within sql server give the group all the necessary permissions/ privileges and then add the users to that group thereafter...

.Net App Deployment Scenario: Privileges For Non-Admin Users

Sep 17, 2007

My VB.net application manipulates data in a local SQL Express database. When the app is installed, the database does not exist, but it cannot be created at run-time by anyone other than a user with administrator privileges. In addition, the application shares the data stored in SQL with a critical 3rd party component that can only reach the database via named DSN (also not existing prior to installation).

I see my primary SQL security options as being:

(1) Use SQL or Mixed Mode authentication with an admin-level username/password combination, or
(2) Create a db user/group with admin-level privileges and grant membership to all NT authenticated users

Secondary problem: Creating the DSN.

Does it make sense to create a Custom Action (.dll) that is called at the end of the installation process in order to create the database, the user security context and the named DSN?


Am I overlooking some built-in functionality provided by Visual Studio 2005 that will accompish some or all of this for me? I am aware that customizing the 'silent' installation of SQL Express to use a different authentication mode requires manifest tweaking -- I just don't know anything about setting up the appropriate security for this situation. Would you put the db and role creation stuff in a SQL script and execute it post-install?

Thanks in advance for any insight you can provide.

Privileges Granted To=##MS_AgentSigningCertificate## As A Security Vulnerability

Dec 6, 2007

A client has received the results of a security scan suggesting that Execute privileges granted to the certificate ##MS_AgentSigningCertificate## on the master database are a security hole which needs to be fixed. I'm unsure of the affect do doing this. We have a very vanilla sql server database, we don't use certificates, we just connect via jdbc to the db and do OLTP work. Are there basic functions associated with ##MS_AgentSigningCertificate## that will fail if I revoke privileges? We only need to be able to log on to a user database and do DML and basic backup and recovery.

Thanks for any info y'all can give me.

SQLServerAgent Security Context Does Not Have Server Autorestart Privileges

Oct 21, 1999

SQL Server in on a ‘member’ server in my company domain (We took the ‘stand-alone’ option when installing NT on this server).

I have set up an NT domain account for SQL ServerAgent ‘Service startup account’ which is a different account than the NT domain account listed in the SQL Server Properties, Security tab, ‘Startup service account’.

I log on to this server with the login in the latter.

Replication is working OK, but my application log keeps filling up with the message “SQLServerAgent security context does not have server autorestart privileges”.

What have I done wrong?
