解決並清除SQL被注入惡意病毒代碼的語句

 

declare @t varchar(255),@c varchar(255)
declare table_cursor cursor for select a.name,b.name
from sysobjects a,syscolumns b ,systypes c
where a.id=b.id and a.xtype='u' and c.name
in ('char', 'nchar', 'nvarchar', 'varchar','text','ntext')
declare @str varchar(500),@str2 varchar(500)
set @str='<script src=http://r01.3322.org/c.js></script>'/*要替換的內容*/
set @str2=''
open table_cursor
fetch next from table_cursor
into @t,@c while(@@fetch_status=0)
begin exec('update [' + @t + '] set [' + @c + ']=replace(cast([' + @c + '] as varchar(8000)),'''+@str+''','''+ @str2 +''')')

fetch next from table_cursor
into @t,@c end close table_cursor deallocate table_cursor;

首先替換代碼裏面的<script src=http://r01.3322.org/c.js></script>爲你的數據庫表裏面被注入的內容，打開MSSQL的SQL查詢分析器執行以下代碼就可以了。
