将有安全问题的SQL过程删除.比较全面.一切为了安全!
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]
