→Monitor POST requests to /components/com_portfoliogallery/ajax_url.php for SQL injection patterns in the 'galleryid' parameter, including OR/GROUP BY/CONCAT/FLOOR(RAND()) error-based payloads and SLEEP()-based time-blind payloads. ↗
→The vulnerable POST parameter is 'galleryid'; alert on values containing SQL keywords such as OR, GROUP BY, CONCAT, SLEEP, CASE WHEN in POST body to this endpoint. ↗
→A high rate of HTTP 500 Internal Server Error responses from /components/com_portfoliogallery/ajax_url.php may indicate active SQL injection exploitation (sqlmap generated 2715 such errors during the PoC run). ↗
→The exploit requires no authentication; any unauthenticated POST to ajax_url.php with the 'post' field set to 'huge_it_portfolio_gallery_ajax' should be treated as suspicious and inspected for injection payloads. ↗

·The file ajax_url.php is directly web-accessible outside the normal Joomla MVC dispatch path, bypassing standard Joomla access controls; restricting direct HTTP access to this file at the web-server level is an effective mitigation. ↗
