    [+] Summary    : This PHP script is a defensive vulnerability checker for CVE-2024-36985 affecting Splunk Enterprise. 
                     It authenticates to a Splunk instance using provided credentials, retrieves the installed Splunk version, and determines whether it falls within the vulnerable ranges. 
    				 The script then enumerates locally installed applications to verify the presence and enabled status of the splunk_archiver app, which is a required condition for exploitation. 
    				 No commands are executed and no exploitation logic is included; the script is strictly designed for detection and assessment purposes 
    				 to help security teams identify potentially vulnerable systems in a safe and controlled manner.
