Joomla! Component Ajax Quiz 1.8 contains an SQL injection vulnerability that allows unauthenticated attackers to execute arbitrary SQL queries by injecting malicious code through the cid parameter. Attackers can send GET requests to index.php with the option=com_ajaxquiz and view=ajaxquiz parameters to extract sensitive database information including table names and column structures.
