→Probe for SQL injection via the 'query' parameter on the 'act=hotword' endpoint of plus/ajax_common.php using a UNION SELECT payload; a successful response body will contain the MD5 hash of the injected numeric value (md5(999999999)). ↗
→Use Shodan query 'http.html:"74cms"' or FOFA queries 'app="74cms"' / 'body="74cms"' to identify potentially vulnerable 74cms 3.2.0 instances exposed on the internet. ↗

·The exploit targets specifically 74cms version 3.2.0; other versions may not be vulnerable or may require a different payload. ↗
·The UNION SELECT injection uses a multibyte character sequence (%錦) as part of the bypass technique; detection rules should account for this encoding trick in the query parameter. ↗
