Joomla! Component JoomCRM 1.1.1 contains an SQL injection vulnerability that allows authenticated attackers to execute arbitrary SQL queries by injecting malicious code through the deal_id parameter. Attackers can send GET requests to index.php with option=com_joomcrm&view=contacts and inject SQL code in the deal_id parameter to extract sensitive database information including table names and schemas.
