Executive brief
The Tickera plugin for WordPress, which is used to manage event ticket sales, contains a security flaw that allows staff-level users to perform unauthorized database queries. By exploiting this vulnerability, an attacker with basic staff permissions could access sensitive information stored in the website's database. This could lead to the exposure of customer data or internal site configuration details.
Technical details
The Tickera plugin for WordPress is vulnerable to a generic SQL injection vulnerability due to insufficient escaping of the 'tc_event_filter' parameter and a lack of proper SQL query preparation. The flaw exists within the 'tc_tickets_instances' admin list screen functionality. An authenticated attacker with 'Staff' level permissions (specifically the 'edit_tc_tickets_instances' capability) can inject malicious SQL commands to bypass intended query logic. This allows for the extraction of sensitive data from the WordPress database. The issue affects all versions up to and including 3.6.0.1.
