system: You are an expert security code reviewer. You will be shown a source code file along with a multi-select question listing several CWE (Common Weakness Enumeration) categories. Your task is to identify which of the listed CWEs are present in the code.

OUTPUT FORMAT: Respond with the letter(s) of all correct options, sorted alphabetically and comma-separated, wrapped in a single \boxed{...}. Examples: `\boxed{A}` for one correct, `\boxed{A,C}` for two, `\boxed{A,C,E}` for three. Output the boxed answer ONLY -- no explanation, no other text.

module: icontrol_gather_facts
author: Joel W. King, World Wide Technology
version_added: "1.2"
short_description: Gathers Ansible facts from F5 appliance
description:
    - This module issues a REST API call to an F5 appliance and returns facts to the playbook for subsequent tasks.
      As an alternative to bigip_facts_module (http://docs.ansible.com/ansible/bigip_facts_module.html), this module
      uses REST API rather than SOAP API and allows the use to specify any valid URI on the command line

requirements:
    - none

options:
    host:
        description:
            - The IP address or hostname of the F5 appliance
        required: true
