`## Title: cmsms-2.2.19 - File Upload - RCE  
## Author: nu11secur1ty  
## Date: 12/29/2023  
## Vendor: https://www.cmsmadesimple.org/  
## Software: https://www.cmsmadesimple.org/downloads-header/cmsms/  
## Reference: https://portswigger.net/web-security/file-upload,  
https://portswigger.net/web-security/file-upload/lab-file-upload-remote-code-execution-via-web-shell-upload  
  
## Description:  
The parameter "fileupload" in type ID is vulnerable to File Upload and  
RCE attacks, it is not sanitized correctly. The attacker can upload a  
virus directly on the server by using this web vulnerability, and then  
he can execute it, this can be the end of this server depending on the  
scenario! In this case, I just uploaded a [WebSocket] connector -  
exploit.html to connect the server with my machine, this is so nasty.  
I am a Penetration Tester, not a stupid cracker! Thank you all!
