CVE-2025-68601 identifies a Cross-Site Request Forgery (CSRF) vulnerability in the Rustaurius Five Star Restaurant Reservations software, affecting all versions up to and including 2.7.7. CSRF vulnerabilities occur when a web application does not adequately verify that requests made to it originate from authenticated and intended users. In this case, an attacker can craft malicious web pages or links that, when visited by an authenticated user of the restaurant reservation system, cause the user’s browser to perform unintended actions such as making, modifying, or canceling reservations. The vulnerability arises because the application lacks proper anti-CSRF protections such as synchronizer tokens or same-site cookie attributes. No CVSS score has been assigned yet, and no known exploits are reported in the wild, but the vulnerability is publicly disclosed and considered published. The attack requires the victim to be authenticated but does not require additional user interaction beyond visiting a malicious site or clicking a link. This vulnerability threatens the integrity and availability of the reservation system by enabling unauthorized state-changing requests, potentially disrupting business operations and customer service. The Rustaurius product is used in hospitality environments, where reservation integrity is critical. The absence of patches or mitigation details in the report suggests that organizations must proactively implement compensating controls until official fixes are released.

For European organizations, particularly those in the hospitality and restaurant sectors using Rustaurius Five Star Restaurant Reservations, this CSRF vulnerability could lead to unauthorized modifications of reservation data. This can cause operational disruptions such as double bookings, cancellations, or fraudulent reservations, damaging customer trust and business reputation. The integrity of reservation data is compromised, and availability may be affected if attackers cause denial of service through mass reservation changes. Confidentiality impact is minimal since the vulnerability does not directly expose sensitive data. However, the indirect effects on business continuity and customer satisfaction can be significant. Given the widespread reliance on online reservation systems in Europe’s large tourism and hospitality industries, the threat could affect numerous businesses, especially those without robust security controls. The lack of known exploits provides a window for mitigation, but the ease of exploitation means attackers could quickly weaponize this vulnerability once details are widely known.

1. Implement anti-CSRF tokens in all state-changing forms and API endpoints to ensure requests originate from legitimate users. 2. Enforce the use of SameSite=strict or lax cookie attributes to limit cookie transmission to first-party contexts. 3. Validate the HTTP Referer and Origin headers on sensitive requests to confirm they come from trusted sources. 4. Restrict HTTP methods to only those necessary (e.g., POST for state changes) and reject unsafe methods. 5. Educate users about the risks of clicking unknown links while authenticated on the reservation platform. 6. Monitor logs for unusual reservation activity that could indicate exploitation attempts. 7. Apply patches or updates from Rustaurius promptly once available. 8. Consider implementing web application firewalls (WAFs) with CSRF detection rules as an interim protective measure. 9. Conduct security audits and penetration testing focused on CSRF and session management controls. 10. Segregate the reservation system network to limit exposure and reduce attack surface.
