• → Monitor HTTP requests to Joomla! endpoints where 'option=com_collectionfactory' and 'task=items' are present with unsanitised values in the 'filter_order' or 'filter_order_Dir' GET parameters — these are the injection points for CVE-2018-17383. ↗
• → Alert on URL-encoded SQL keywords (e.g. EXTRACTVALUE, CONCAT, SELECT, ELT, CONCAT_WS, USER(), DATABASE(), VERSION()) appearing in the 'filter_order' or 'filter_order_Dir' query-string parameters targeting 'com_collectionfactory'. ↗
• → The decoded payload uses EXTRACTVALUE-based error-based SQL injection to exfiltrate USER(), DATABASE(), and VERSION() — look for database error messages in HTTP responses to requests targeting this component. ↗

• · The exploit PoC uses 'localhost' as a placeholder; in real attacks the host will vary. Detection rules must match on the query-string parameters ('option=com_collectionfactory', 'task=items', 'filter_order', 'filter_order_Dir') rather than the host. ↗
• · The vulnerable version is specifically 4.1.9 of the Collection Factory component; detections scoped to version strings should target this exact version. ↗
