## Description:  
The attacker who already has an account can upload a fake module to  
the system and can execute the content from this module  
on the server. In this example, the attacker executes an info file  
from the already fake uploaded module and gets all information for  
this system. This is a CRITICAL Vulnerability.  
The problem is that these developers are not making a strong  
sanitizing upload function and do not restrict the execution from  
inside  
of the server.  
  
## Staus: HIGH Vulnerability  
  
[+]Exploit: prostak.php  
  
- - - NOTE: The attacker also can upload an EXE file, which file he  
can execute or download!
