## 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

can execute or download!
