CVE-2024-26445 identifies a Cross-Site Request Forgery (CSRF) vulnerability in flusity-CMS version 2.33, specifically within the /core/tools/delete_place.php endpoint. 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 where they are authenticated. In this case, the vulnerability allows an attacker to execute unauthorized delete operations on the 'place' resource without the user's explicit consent. The vulnerability does not require the attacker to have any privileges or prior authentication, but it does require the victim to interact with a malicious link or webpage (user interaction). The CVSS 3.1 vector string (AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N) indicates that the attack is network-based, requires low attack complexity, no privileges, but does require user interaction. The scope is changed, meaning the vulnerability affects resources beyond the initially vulnerable component. The impact is limited to partial loss of confidentiality and integrity, with no availability impact. No patches or known exploits are currently available, but the vulnerability is publicly disclosed and should be addressed promptly. The underlying weakness is classified under CWE-352, which is the standard identifier for CSRF vulnerabilities.

The primary impact of this vulnerability is unauthorized modification and potential deletion of data within the flusity-CMS environment, specifically related to the 'place' resource. This can lead to data integrity issues, unauthorized data loss, and potential exposure of sensitive information depending on how the CMS manages and displays deleted content. Organizations relying on flusity-CMS for content management could face operational disruptions and reputational damage if attackers exploit this vulnerability to manipulate or delete critical data. Since the vulnerability requires user interaction, phishing or social engineering campaigns could be used to trick users into triggering the exploit. The lack of authentication requirements lowers the barrier for attackers, increasing the risk of exploitation in environments where users have elevated privileges. Although no availability impact is noted, the integrity and confidentiality breaches could have cascading effects on business processes and compliance with data protection regulations.

To mitigate CVE-2024-26445, organizations should implement the following specific measures: 1) Apply any available patches or updates from the flusity-CMS vendor as soon as they are released. 2) If patches are not yet available, implement anti-CSRF tokens in all state-changing requests, especially for the /core/tools/delete_place.php endpoint, to ensure requests originate from legitimate users. 3) Enforce strict SameSite cookie attributes (SameSite=Lax or Strict) to reduce the risk of CSRF attacks via cross-site requests. 4) Educate users about the risks of clicking on suspicious links or visiting untrusted websites while authenticated to the CMS. 5) Implement web application firewalls (WAFs) with rules designed to detect and block CSRF attack patterns targeting the vulnerable endpoint. 6) Restrict user privileges to the minimum necessary, limiting access to sensitive CMS functions only to trusted users. 7) Monitor logs for unusual or unauthorized delete requests to detect potential exploitation attempts early. 8) Consider implementing multi-factor authentication (MFA) to reduce the risk of session hijacking and unauthorized access that could be leveraged in conjunction with CSRF.
