The CVE-2019-12465 description identifies ajax_rulesuggest.php as the vulnerable file where the 'term' parameter is unsafely embedded into a SQL query. Runtime detection would observe the script's execution (typically represented as the global scope in PHP) processing the 'term' input and constructing the SQL query. While PHP's global scope does not have a named function, profilers often reference the script's entry point as the primary execution context. This matches the exploit's entry vector via ajax_rulesuggest.php?term=, making the script's main code the focal point for detection.
