将有安全问题的SQL过程删除。
删除了调用shell，注册表，COM组件的破坏权限。
MS SQL Server 2000
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] |
恢复脚本
