CVE-2024-24524 is a Cross Site Request Forgery (CSRF) vulnerability identified in flusity-CMS version 2.33, specifically within the add_menu.php component. CSRF vulnerabilities allow attackers to trick authenticated users into submitting unauthorized requests to a web application, potentially leading to unauthorized actions. In this case, the vulnerability permits remote attackers to execute arbitrary code on the server by exploiting the lack of proper CSRF protections in the add_menu.php script. The CVSS v3.1 base score is 8.8, indicating a high severity level, with an attack vector of network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), but requiring user interaction (UI:R). The impact on confidentiality, integrity, and availability is rated high (C:H/I:H/A:H), meaning an attacker can fully compromise the system. Although no known exploits have been reported in the wild yet, the vulnerability poses a significant risk due to the potential for remote code execution without authentication. The vulnerability is categorized under CWE-352, which covers CSRF issues. The lack of available patches at the time of publication increases the urgency for organizations to implement alternative mitigations or monitor for suspicious activity. The flaw arises from insufficient validation of requests in the add_menu.php component, allowing attackers to craft malicious requests that, when executed by a logged-in user, can lead to arbitrary code execution on the server hosting flusity-CMS.

The impact of CVE-2024-24524 is severe for organizations using flusity-CMS, as exploitation can lead to full system compromise. Attackers can execute arbitrary code remotely, potentially leading to data breaches, defacement, service disruption, or use of the compromised server as a pivot point for further attacks. The vulnerability affects confidentiality by exposing sensitive data, integrity by allowing unauthorized modifications, and availability by potentially causing denial of service. Since no authentication is required and the attack only needs user interaction, phishing or social engineering could be used to trigger the exploit. This increases the risk profile, especially for organizations with many users or public-facing CMS instances. The lack of patches means organizations must rely on mitigations, increasing operational complexity. The threat is particularly critical for sectors relying on flusity-CMS for web content management, including government, education, and small to medium enterprises, where security resources may be limited.

To mitigate CVE-2024-24524, organizations should immediately implement CSRF protections such as synchronizer tokens or double-submit cookies in the flusity-CMS environment, especially around the add_menu.php component. Restrict access to the add_menu.php script by IP whitelisting or network segmentation to limit exposure. Employ web application firewalls (WAFs) with custom rules to detect and block suspicious CSRF attempts targeting the vulnerable endpoint. Educate users to avoid clicking on untrusted links or performing sensitive actions without verifying the source. Monitor web server logs and application logs for unusual POST requests or patterns indicative of CSRF exploitation attempts. If possible, disable or restrict the add_menu.php functionality until a vendor patch is available. Regularly check for updates from the flusity-CMS vendor and apply patches promptly once released. Conduct security assessments and penetration testing focused on CSRF and related vulnerabilities in the CMS environment. Implement multi-factor authentication (MFA) to reduce the risk of session hijacking that could facilitate exploitation.
