The Tourfic – Ultimate Hotel Booking, Travel Booking & Apartment Booking WordPress plugin, widely used for managing hotel and travel bookings integrated with WooCommerce, suffers from a Cross-Site Request Forgery (CSRF) vulnerability identified as CVE-2024-8319. This vulnerability exists in all versions up to and including 2.11.20 due to missing or improper nonce validation in multiple critical functions: 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. Nonces in WordPress are security tokens used to verify that requests originate from legitimate users and prevent unauthorized commands. The absence or incorrect implementation of nonce checks allows attackers to craft malicious requests that, when executed by an authenticated administrator (via social engineering such as clicking a link), can perform unauthorized actions. These actions include resending order status emails, modifying visitor and order details, editing check-in and check-out information, bulk updating order statuses, removing room order IDs, and deleting old review data. While the vulnerability does not directly impact confidentiality or availability, it compromises the integrity of booking and order data, potentially leading to operational disruptions and loss of trust. The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N) reflects a network attack vector with low attack complexity, no privileges required, but requiring user interaction, and limited to integrity impact without affecting confidentiality or availability. No public exploits are currently known, but the vulnerability poses a risk to any site using the affected plugin versions, especially those with high administrative activity.

The primary impact of CVE-2024-8319 is on the integrity of booking and order data within affected WordPress sites using the Tourfic plugin. Unauthorized modification of order statuses, visitor details, and check-in/out information can lead to incorrect bookings, customer dissatisfaction, and operational inefficiencies. Resending order status emails without authorization could cause confusion or phishing risks if attackers manipulate email content. Bulk order status changes and deletion of review fields may disrupt business analytics and customer feedback mechanisms. Although the vulnerability does not directly expose sensitive data or cause denial of service, the ability to alter critical booking information undermines trust and could lead to financial losses or reputational damage. Organizations relying on this plugin for hotel, travel, or apartment bookings are at risk of administrative account misuse through social engineering, potentially affecting customer experience and business continuity.

To mitigate CVE-2024-8319, organizations should first update the Tourfic plugin to a version where the vulnerability is patched once available. In the absence of an immediate patch, administrators should implement the following measures: 1) Restrict administrative access to trusted personnel only and enforce strong authentication mechanisms such as multi-factor authentication (MFA) to reduce the risk of compromised admin accounts. 2) Educate administrators about the risks of CSRF and social engineering attacks, emphasizing caution when clicking on unsolicited links or emails. 3) Employ Web Application Firewalls (WAFs) with rules designed to detect and block suspicious POST requests targeting the vulnerable plugin endpoints. 4) Monitor logs for unusual administrative actions or bulk updates that could indicate exploitation attempts. 5) Consider temporarily disabling or limiting the use of affected plugin functions if feasible until a patch is applied. 6) Review and implement nonce validation in custom plugin code or request vendor support to ensure proper security controls are in place. These steps help reduce the attack surface and prevent unauthorized administrative actions via CSRF.
