The vulnerability identified as CVE-2024-25419 affects flusity-CMS version 2.33 and represents a critical cross-site request forgery flaw within the administrative update_menu.php component. This vulnerability allows attackers to execute unauthorized administrative actions on behalf of authenticated users without their knowledge or consent. The flaw exists in the core tools directory of the CMS, specifically within the update_menu.php file which handles menu update operations. The vulnerability stems from the absence of proper anti-CSRF token validation mechanisms in the affected component, making it susceptible to exploitation by malicious actors who can craft malicious requests that appear to originate from legitimate administrators.
The technical nature of this CSRF vulnerability places it squarely within CWE-352, which defines cross-site request forgery as a condition where an attacker can induce users to perform actions they did not intend to perform. The flaw operates by leveraging the trust relationship between the web application and the authenticated user, where the application fails to verify the authenticity of requests originating from the user's browser. In the context of flusity-CMS, this means that an attacker could potentially manipulate menu structures, add malicious menu items, or modify existing menu configurations without the administrator's awareness. The vulnerability is particularly dangerous because it targets administrative functionality, potentially allowing attackers to establish persistence mechanisms or create backdoors within the CMS infrastructure.
The operational impact of this vulnerability extends beyond simple menu manipulation and could enable attackers to compromise the entire CMS administration interface. An attacker exploiting this CSRF flaw could potentially add new administrative users, modify existing user permissions, alter website content, or even install malicious code through the menu update functionality. This represents a significant threat to the integrity and confidentiality of the web application, as it allows unauthorized modifications to the content management system's core functionality. The vulnerability also aligns with ATT&CK technique T1078.004 which covers legitimate credentials, as successful exploitation could lead to persistent access through administrative privileges. Organizations using flusity-CMS v2.33 are at risk of complete system compromise if this vulnerability remains unpatched, as it provides a pathway for attackers to gain unauthorized administrative control over the content management system.
Mitigation strategies for CVE-2024-25419 should prioritize immediate patching of the affected flusity-CMS version to address the missing CSRF protection mechanisms in the update_menu.php component. Organizations should implement proper anti-CSRF token validation throughout the application's administrative interfaces, ensuring that each request contains a unique, unpredictable token that is validated before any administrative action is executed. Additionally, administrators should conduct thorough security assessments of the CMS to identify any other components that may be vulnerable to similar CSRF attacks. The implementation of Content Security Policy headers and proper session management practices can further reduce the attack surface. Organizations should also consider implementing web application firewalls to detect and block suspicious requests attempting to exploit CSRF vulnerabilities. Regular security monitoring and vulnerability scanning should be maintained to identify similar weaknesses in other CMS components or third-party integrations that could be exploited to achieve similar unauthorized administrative access.
