CVE-2024-26352 identifies a Cross-Site Request Forgery (CSRF) vulnerability in flusity-CMS version 2.33, specifically within the /core/tools/add_places.php component. CSRF vulnerabilities occur when an attacker tricks an authenticated user into submitting a forged HTTP request, causing the user’s browser to perform unwanted actions on a web application in which they are authenticated. In this case, the vulnerability allows attackers to perform high-impact actions without requiring any privileges, exploiting the lack of proper CSRF protections such as anti-CSRF tokens or origin validation. The CVSS v3.1 score of 8.8 reflects the high severity, with an attack vector over the network, low complexity, no privileges required, but requiring user interaction (the victim must be tricked into clicking a malicious link or visiting a crafted webpage). The vulnerability affects confidentiality, integrity, and availability, meaning attackers could potentially manipulate sensitive data, alter system configurations, or disrupt service availability. No patches or exploit code are currently publicly available, but the vulnerability’s presence in a core CMS component makes it a critical risk for websites relying on flusity-CMS. Organizations using this CMS should prioritize mitigation to prevent potential exploitation.

The impact of CVE-2024-26352 is significant for organizations using flusity-CMS, as successful exploitation can lead to unauthorized actions performed with the privileges of an authenticated user. This can result in data breaches, unauthorized configuration changes, or service disruptions, affecting confidentiality, integrity, and availability of web applications. Since the vulnerability requires user interaction but no authentication or elevated privileges, it can be exploited remotely via social engineering techniques such as phishing. The broad network attack vector means attackers can target any user with access to the vulnerable CMS interface. This can lead to reputational damage, regulatory penalties, and operational downtime for affected organizations. The lack of known exploits in the wild currently provides a window for proactive mitigation before widespread attacks occur.

To mitigate CVE-2024-26352, organizations should implement robust CSRF protections immediately. This includes adding anti-CSRF tokens to all state-changing requests, validating the HTTP Referer or Origin headers to ensure requests originate from trusted sources, and enforcing same-site cookie attributes to limit cross-origin requests. Additionally, updating flusity-CMS to a patched version once available is critical. Until patches are released, administrators should consider restricting access to the vulnerable component (/core/tools/add_places.php) via web application firewalls or IP whitelisting. User education to recognize phishing attempts can reduce the risk of user interaction exploitation. Regular security audits and monitoring for unusual activity related to this component can help detect attempted exploitation early.
