	- GetSimpleCMS Version 3.2.1 suffers from arbitrary file upload vulnerability which allows an attacker to upload a HTML page.
	- The main reason of this vulnerability is that the application uses a blacklist technique to compare the file aganist mime types and extensions.
	- If the mime type or the extension is in the blacklist array , the application won't upload it.
	- For exploiting this vulnerability we will create a file with mutiple extensions for example ""
	- The application will check the mime type and extension of the file which is "fr" aganist the blacklist array mime type and extensions.
	- and ofcourse "fr" extension won't be in the blacklist array so the application will upload it successfully.
	- The uploaded file will be under the "data/uploads/" folder.
	- The application should use whitelisting technique which compare the file extensions and mime types aganist
	- acceptable mime types and extensions for more information google for "whitelisting vs blacklisting"
