The CVE-2024-24468 vulnerability represents a critical cross site request forgery flaw within the flusity-CMS version 2.33 platform that exposes the system to remote code execution attacks. This vulnerability specifically targets the add_customblock.php component, which serves as a critical entry point for malicious actors seeking to compromise the affected content management system. The flaw stems from insufficient validation of user requests and lacks proper anti-CSRF token implementation, creating an exploitable condition that allows unauthorized users to manipulate the system through crafted requests.
The technical implementation of this vulnerability resides in the insufficient input validation mechanisms within the add_customblock.php script. When a user submits requests to this endpoint, the system fails to properly verify the authenticity of the request origin or validate the presence of required anti-CSRF tokens. This weakness enables attackers to construct malicious requests that appear legitimate to the CMS, allowing them to execute arbitrary code on the server. The vulnerability operates under the common attack pattern where an attacker tricks a victim into performing actions without their knowledge, leveraging the trust relationship between the user and the web application. This type of vulnerability maps directly to CWE-352, which specifically addresses Cross-Site Request Forgery weaknesses in web applications.
The operational impact of this vulnerability extends beyond simple data theft or modification, as it provides attackers with the capability to execute arbitrary code on the target system. Successful exploitation could lead to complete system compromise, allowing attackers to install backdoors, exfiltrate sensitive data, or establish persistent access to the compromised environment. The remote nature of this attack means that threat actors can exploit the vulnerability from anywhere on the internet without requiring physical access to the system. Organizations running flusity-CMS version 2.33 are particularly vulnerable as this represents a critical security gap that could be exploited by automated scanning tools or determined attackers seeking to compromise web applications.
Mitigation strategies for CVE-2024-24468 should prioritize immediate remediation through official patches provided by the flusity-CMS vendor, as this represents a known vulnerability that requires urgent attention. Organizations should implement comprehensive CSRF protection measures including the deployment of anti-CSRF tokens for all state-changing requests, proper request origin validation, and session management controls. The implementation of Content Security Policy headers and proper input sanitization can further reduce the attack surface. Additionally, network-level protections such as web application firewalls and intrusion detection systems should be configured to monitor for suspicious requests targeting the vulnerable add_customblock.php endpoint. Security teams should also conduct comprehensive vulnerability assessments to identify any other potential CSRF vulnerabilities within the CMS or related applications, as this attack vector often indicates broader security gaps in web application architectures. The vulnerability classification aligns with ATT&CK technique T1213 which covers data from information repositories, and T1059 which encompasses command and scripting interpreter attacks, indicating the potential for both data exfiltration and system compromise through this flaw.
