CVE-2024-46394 identifies a Cross-Site Request Forgery (CSRF) vulnerability in FrogCMS version 0.9.5, specifically targeting the /admin/?/user/add administrative endpoint. CSRF vulnerabilities allow attackers to trick authenticated users into submitting unwanted requests to a web application, thereby executing actions without the user's consent. In this case, the vulnerability enables an attacker to potentially add new users or manipulate user-related functions within the CMS. The CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H) indicates that the attack can be performed remotely over the network with low attack complexity, requiring low privileges and user interaction, and affects confidentiality, integrity, and availability at a high level. The vulnerability stems from the absence or improper implementation of anti-CSRF protections, such as missing or ineffective CSRF tokens in the user addition workflow. While no patches or exploits are currently documented, the flaw represents a critical risk for administrators who may be tricked into executing malicious requests, potentially leading to unauthorized account creation, privilege escalation, or disruption of CMS operations. This vulnerability is categorized under CWE-352, which covers CSRF weaknesses. Organizations using FrogCMS 0.9.5 should prioritize remediation to prevent exploitation.

The impact of CVE-2024-46394 is significant for organizations relying on FrogCMS for content management. Successful exploitation can lead to unauthorized user creation or modification, enabling attackers to escalate privileges or gain persistent access to administrative functions. This compromises the confidentiality of sensitive data managed within the CMS, the integrity of website content and user accounts, and the availability of the CMS through potential disruption or misuse of administrative capabilities. Given the low complexity and remote exploitability, attackers can leverage social engineering to induce authenticated administrators to perform malicious actions unknowingly. This can result in defacement, data breaches, or complete takeover of the CMS environment. Organizations with public-facing FrogCMS installations are particularly vulnerable, potentially affecting their reputation and operational continuity.

To mitigate CVE-2024-46394, organizations should implement robust anti-CSRF protections in FrogCMS, especially on sensitive administrative endpoints like /admin/?/user/add. This includes integrating unique, unpredictable CSRF tokens in all state-changing requests and validating these tokens server-side before processing. Additionally, enforcing strict user session management and limiting administrative access to trusted networks or VPNs can reduce exposure. Administrators should be trained to recognize phishing and social engineering attempts that could trigger CSRF attacks. Monitoring and logging administrative actions can help detect suspicious activities early. If possible, upgrading to a patched version of FrogCMS or applying vendor-provided fixes is recommended once available. As a temporary measure, disabling or restricting access to vulnerable endpoints until a fix is deployed can reduce risk. Employing web application firewalls (WAFs) with CSRF detection rules may also provide an additional layer of defense.
