CVE-2024-25419 is a high-severity vulnerability identified in flusity-CMS version 2.33, specifically involving a Cross-Site Request Forgery (CSRF) attack vector through the component located at /core/tools/update_menu.php. CSRF vulnerabilities allow an attacker to trick an authenticated user into submitting a forged HTTP request, which can cause the user’s browser to perform unwanted actions on a web application in which they are currently authenticated. In this case, the vulnerable endpoint is related to menu updates within the CMS, which likely requires administrative privileges. The CVSS 3.1 base score of 8.8 reflects the critical nature of this vulnerability, 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 metrics indicate high confidentiality, integrity, and availability impacts (C:H/I:H/A:H), meaning successful exploitation could lead to full compromise of the CMS, including unauthorized changes to menu structures, potential injection of malicious content, or disruption of service. The vulnerability does not require prior authentication, increasing its risk, but does require the victim to interact with a malicious link or page. No known exploits in the wild have been reported yet, and no vendor or product information beyond the CMS name and version is provided. The vulnerability is classified under CWE-352, which corresponds to CSRF attacks. No patch links are currently available, indicating that remediation may not yet be released or publicly disclosed.

For European organizations using flusity-CMS v2.33, this vulnerability poses a significant risk. Given the high confidentiality, integrity, and availability impacts, attackers could manipulate website content, deface pages, or inject malicious scripts that could lead to data breaches or further compromise of internal networks. Organizations relying on this CMS for public-facing websites or intranet portals could face reputational damage, loss of customer trust, and potential regulatory penalties under GDPR if personal data is exposed or manipulated. The requirement for user interaction means phishing or social engineering campaigns could be used to exploit this vulnerability, increasing the attack surface. Additionally, disruption of website availability could impact business operations, especially for e-commerce or service delivery platforms. The lack of authentication requirement means even non-privileged attackers can attempt exploitation, increasing the threat level. The absence of known exploits in the wild currently provides a small window for mitigation before active exploitation begins.

European organizations should immediately assess their use of flusity-CMS v2.33 and restrict access to the /core/tools/update_menu.php endpoint where possible, ideally limiting it to trusted IP addresses or internal networks. Implementing anti-CSRF tokens in all state-changing requests is critical; if the CMS does not natively support this, organizations should consider deploying web application firewalls (WAFs) with custom rules to detect and block suspicious CSRF attempts targeting this endpoint. User education to recognize phishing attempts that could trigger CSRF attacks is also important. Monitoring web server logs for unusual POST requests to the update_menu.php script can help detect attempted exploitation. Until an official patch is released, organizations should consider disabling or restricting the vulnerable functionality if feasible. Regular backups of CMS configurations and website content should be maintained to enable rapid restoration in case of compromise. Finally, organizations should subscribe to vendor advisories and CVE databases to apply patches promptly once available.
