SQL Server危险扩展删除与恢复详解

删除了调用shell，注册表，COM组件的破坏权限

MS SQL SERVER2000

使用系统帐户登陆查询分析器

运行以下脚本:

use master

exec sp_dropextendedproc 'xp_cmdshell'

exec sp_dropextendedproc 'xp_enumgroups'

exec sp_dropextendedproc 'xp_loginconfig'

exec sp_dropextendedproc 'xp_enumerrorlogs'

exec sp_dropextendedproc 'xp_getfiledetails'

exec sp_dropextendedproc 'Sp_OACreate'

exec sp_dropextendedproc 'Sp_OADestroy'

exec sp_dropextendedproc 'Sp_OAGetErrorInfo'

exec sp_dropextendedproc 'Sp_OAGetProperty'

exec sp_dropextendedproc 'Sp_OAMethod'

exec sp_dropextendedproc 'Sp_OASetProperty'

exec sp_dropextendedproc 'Sp_OAStop'

exec sp_dropextendedproc 'xp_regaddmultistring'

exec sp_dropextendedproc 'xp_regdeletekey'

exec sp_dropextendedproc 'xp_regdeletevalue'

exec sp_dropextendedproc 'xp_regenumvalues'

exec sp_dropextendedproc 'xp_regremovemultistring'

exec sp_dropextendedproc 'xp_regwrite'

drop procedure sp_makewebtask

go

删除所有危险的扩展:

exec sp_dropextendedproc 'xp_cmdshell' [删除此项扩展后,将无法远程连接数据库]

以下3个存储过程会在SQL SERVER恢复备份时被使用,非必要请勿删除

#exec sp_dropextendedproc 'xp_dirtree' [删除此项扩展后,将无法新建或附加数据库]

#exec sp_dropextendedproc 'Xp_regread' [删除此项扩展后, 还原数据库辅助]

#exec sp_dropextendedproc 'xp_fixeddrives' [删除此项扩展后,将无法还原数据库]
