資料庫被注入解決方案

declare @delStr nvarchar(500)

set @delStr='<script src=http://www.kansm.com/js/common.js></script>'  --這裡被注入的字段串

set nocount on

declare @tableName nvarchar(100),@columnName nvarchar(100),@tbID int,@iRow int,@iResult int

declare @sql nvarchar(2000)

set @iResult=0

declare cur cursor for

select name,id from sysobjects where xtype='U'

open cur

fetch next from cur into @tableName,@tbID

while @@fetch_status=0

begin

   declare cur1 cursor for

        select name from syscolumns where xtype in (231,167,239,175, 35, 99) and [email protected]

   open cur1

   fetch next from cur1 into @columnName

   while @@fetch_status=0

   begin       

     set @sql='update [' + @tableName + '] set ['+ @columnName +']= SUBSTRING([' + @columnName + '],' + '1, PATINDEX( ''%' + @delStr + '%'', [' + @columnName + '])-1) + ' + 'SUBSTRING([' + @columnName + '], PATINDEX( ''%' + @delStr + '%'', [' + @columnName + ']) + ' + 'len(''' + @delStr + ''') , datalength([' + @columnName + '])) where ['[email protected]+'] like ''%'[email protected]+'%'''

      exec sp_executesql @sql     

      set @iRow=@@rowcount

      set @[email protected][email protected]

      if @iRow>0

      begin

          print '表：'[email protected]+',列:'[email protected]+'被更新'+convert(varchar(10),@iRow)+'條記錄;'

      end     

      fetch next from cur1 into @columnName

   end

   close cur1

   deallocate cur1

   fetch next from cur into @tableName,@tbID

end

print '資料庫共有'+convert(varchar(10),@iResult)+'條記錄被更新!!!'

close cur

deallocate cur

set nocount off
