  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]

  恢复脚本

  use master

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

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

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

  EXEC sp_addextendedproc xp_enumerrorlogs ,@dllname ='xpstar.dll'

  EXEC sp_addextendedproc xp_getfiledetails ,@dllname ='xpstar.dll'

  EXEC sp_addextendedproc Sp_OACreate ,@dllname ='odsole70.dll'

  EXEC sp_addextendedproc Sp_OADestroy ,@dllname ='odsole70.dll'

  EXEC sp_addextendedproc Sp_OAGetErrorInfo ,@dllname ='odsole70.dll'

  EXEC sp_addextendedproc Sp_OAGetProperty ,@dllname ='odsole70.dll'

  EXEC sp_addextendedproc Sp_OAMethod ,@dllname ='odsole70.dll'

  EXEC sp_addextendedproc Sp_OASetProperty ,@dllname ='odsole70.dll'

  EXEC sp_addextendedproc Sp_OAStop ,@dllname ='odsole70.dll'

  EXEC sp_addextendedproc xp_regaddmultistring ,@dllname ='xpstar.dll'

  EXEC sp_addextendedproc xp_regdeletekey ,@dllname ='xpstar.dll'

  EXEC sp_addextendedproc xp_regdeletevalue ,@dllname ='xpstar.dll'

  EXEC sp_addextendedproc xp_regenumvalues ,@dllname ='xpstar.dll'

  EXEC sp_addextendedproc xp_regremovemultistring ,@dllname ='xpstar.dll'

  EXEC sp_addextendedproc xp_regwrite ,@dllname ='xpstar.dll'

  EXEC sp_addextendedproc xp_dirtree ,@dllname ='xpstar.dll'

  EXEC sp_addextendedproc xp_regread ,@dllname ='xpstar.dll'

  EXEC sp_addextendedproc xp_fixeddrives ,@dllname ='xpstar.dll'

  go

  全部复制到"SQL查询分析器"

  点击菜单上的--"查询"--"执行",就会将有安全问题的SQL过程删除。
