教你如何清除SQL被注入恶意病毒代码
在SQL查询分析器执行以下代码就可以了。
01.declare @t varchar(255),@c varchar(255)
02.declare table_cursor cursor for select a.name,b.name
03.from sysobjects a,syscolumns b ,systypes c
04.where a.id=b.id and a.xtype='u' and c.name
05.in ('char', 'nchar', 'nvarchar', 'varchar','text','ntext')
06.declare @str varchar(500),@str2 varchar(500)
07.set @str='<script src=http://r01.3322.org/c.js></script>'/*要替换的内容*/
08.set @str2=''
09.open table_cursor
10.fetch next from table_cursor
11.into @t,@c while(@@fetch_status=0)
12.begin exec('update [' + @t + '] set [' + @c + ']=replace(cast([' + @c + '] as varchar(8000)),'''+@str+''','''+ @str2 +''')')
13.fetch next from table_cursor 14.into @t,@c end close table_cursor deallocate table_cursor;
