Technical details
An SQL injection vulnerability exists in the Webkul Ajax Quiz component (com_ajaxquiz) version 1.8 for Joomla. The flaw is located in the 'cid' parameter handled by the 'ajaxquiz' view. An unauthenticated remote attacker can exploit this by sending specially crafted GET requests to index.php, using UNION-based SQL injection techniques to bypass intended query logic. Successful exploitation allows the attacker to extract sensitive metadata, such as table names and column structures, and potentially access sensitive record data from the underlying database. The extension has been unpublished from the Joomla Extensions Directory.
