CVE-2024-8319 in Tourfic Plugin
Summary
by MITRE • 08/30/2024
The Tourfic plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 2.11.20. This is due to missing or incorrect nonce validation on the tf_order_status_email_resend_function, tf_visitor_details_edit_function, tf_checkinout_details_edit_function, tf_order_status_edit_function, tf_order_bulk_action_edit_function, tf_remove_room_order_ids, and tf_delete_old_review_fields functions. This makes it possible for unauthenticated attackers to resend order status emails, update visitor/order details, edit check-in/out details, edit order status, perform bulk order status updates, remove room order IDs, and delete old review fields, respectively, via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

The vulnerability identified as CVE-2024-8319 affects the Tourfic plugin for WordPress, a popular booking and tour management solution. This critical security flaw stems from inadequate CSRF protection mechanisms within multiple administrative functions of the plugin. The vulnerability exists in all versions up to and including 2.11.20, making it a widespread concern for WordPress sites utilizing this booking management system. The absence of proper nonce validation creates a significant attack surface that could be exploited by malicious actors to manipulate booking data and administrative functions without proper authorization.
The technical implementation of this vulnerability manifests through several specific functions within the plugin's codebase including tf_order_status_email_resend_function, tf_visitor_details_edit_function, tf_checkinout_details_edit_function, tf_order_status_edit_function, tf_order_bulk_action_edit_function, tf_remove_room_order_ids, and tf_delete_old_review_fields. These functions lack proper CSRF token validation, which is a fundamental security measure designed to prevent unauthorized requests from being executed on behalf of authenticated users. The vulnerability operates under the CWE-352 classification as a Cross-Site Request Forgery, where attackers can exploit the missing validation to perform unauthorized administrative actions. This flaw directly violates the principle of least privilege and authorization checks that should be enforced for all administrative operations within WordPress plugins.
The operational impact of this vulnerability extends beyond simple data manipulation to potentially compromise the integrity and availability of booking systems. Attackers could resend order status emails to spam recipients, modify visitor information, alter check-in and check-out details, change order statuses, perform bulk updates that could affect multiple bookings simultaneously, remove room order identifiers that might disrupt reservation tracking, and delete review fields that could impact customer feedback systems. These actions could lead to financial losses, data corruption, privacy breaches, and operational disruptions for businesses relying on the Tourfic plugin for their booking management. The vulnerability is particularly dangerous because it requires minimal user interaction from the administrator, merely tricking them into clicking a malicious link, making it a stealthy and effective attack vector.
The exploitation of this vulnerability aligns with ATT&CK technique T1566.001 which involves phishing attacks and social engineering to trick users into executing malicious requests. The attack scenario typically involves an administrator receiving a phishing email containing a malicious link that, when clicked, automatically executes one of the vulnerable functions. This type of attack is particularly insidious because it leverages the administrator's trusted session and privileges to perform actions that could have significant business impact. The vulnerability represents a critical gap in the plugin's security architecture and highlights the importance of implementing proper CSRF protection mechanisms in all WordPress plugin functions that modify data or perform administrative operations. Organizations should immediately update to the latest version of the Tourfic plugin where this vulnerability has been patched, and consider implementing additional security measures such as two-factor authentication and regular security audits to prevent similar vulnerabilities from being introduced in other plugin components.
The broader implications of this vulnerability demonstrate the critical importance of security testing and validation in WordPress plugin development. Many plugins fail to implement proper CSRF protection mechanisms, creating widespread security risks across the WordPress ecosystem. This vulnerability serves as a reminder that even widely-used plugins can contain critical security flaws that affect thousands of websites. The attack vector emphasizes the need for comprehensive security testing including penetration testing and code review processes that specifically validate the implementation of security controls such as nonces and CSRF protection. Organizations should also consider implementing web application firewalls and monitoring systems to detect and prevent exploitation attempts targeting known vulnerabilities in their WordPress installations.
