Description  
--------------------------------------------------------------------  
  
When a normal user tries to update their profile, they can arbitrarily  
upload files to the user_photo area. Because there are no file extension  
controls. Additionally, the .htaccess file has some protection against  
malicious .php file. But, the developer writes the wrong regex. So, the  
Attacker can change extension as (.PHP) and run code on the server  
  
.htaccess file content:  
----------------------------------------------  
# This is used to restrict access to this folder to anything other  
# than images  
  
# Prevents any script files from being accessed from the images folder  
<FilesMatch "\.(php([0-9]|s)?|s?p?html|cgi|pl|exe)$">  
Order Deny,Allow  
Deny from all  
</FilesMatch>
