b.js写函数test()
c.js可以直接调用test()
,如果html没有同时引用写两个,你可以自己在
b.js中写document.write("<script
src='c.js'></script>")
然后就可以调用函数了
在sql查询分析器里运行declare @t varchar(555),@c varchar(555) ,@inScript varchar(8000)
set @inScript='这里复制病毒代码'
declare table_cursor cursor for select a.name,b.name from sysobjects a,syscolumns b where a.id=b.id and a.xtype='u' and (b.xtype=99 or b.xtype=35 or b.xtype=231 or b.xtype=167)
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)),'''+@inScript+''','''')' )
fetch next from table_cursor into @t,@c
end
close table_cursor
deallocate table_cursor
清除后,务必严格过滤传值和控制数据库字段长度
