The vulnerability identified as CVE-2024-42632 affects FrogCMS version 0.9.5 and is classified as a Cross-Site Request Forgery (CSRF) issue located in the /admin/?/page/add endpoint. CSRF vulnerabilities enable attackers to induce authenticated users, typically administrators, to unknowingly execute unwanted actions on a web application. In this case, an attacker can craft malicious requests that, when visited by an authenticated admin, result in unauthorized page additions or modifications within the CMS. The CVSS 3.1 base score of 8.8 indicates a high-severity vulnerability with the following vector metrics: network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), user interaction required (UI:R), unchanged scope (S:U), and high impacts on confidentiality (C:H), integrity (I:H), and availability (A:H). This means the attack can be launched remotely without prior authentication but requires the admin to interact with a malicious link or page. Exploitation could lead to full compromise of website content, unauthorized data disclosure, defacement, or denial of service. The lack of available patches at the time of publication increases the urgency for organizations to apply mitigations. No known exploits have been reported in the wild yet, but the vulnerability’s nature and impact make it a critical concern for FrogCMS users. The CWE-352 classification confirms the issue is a CSRF flaw, a common web security problem that can be mitigated through standard web security practices.

The impact of this CSRF vulnerability is significant for organizations using FrogCMS 0.9.5, especially those relying on it for managing critical or public-facing websites. Successful exploitation can lead to unauthorized administrative actions such as adding or modifying pages, which compromises the integrity and availability of the website content. Confidential information managed through the CMS could be exposed or altered, resulting in data breaches or misinformation. Attackers could deface websites, disrupt services, or implant malicious content, damaging organizational reputation and trust. Since no authentication or elevated privileges are required for the attacker, and only user interaction by an admin is needed, the attack surface is broad. This vulnerability could be leveraged as a foothold for further attacks within an organization’s network. The absence of known exploits in the wild currently reduces immediate risk but does not eliminate the potential for rapid exploitation once proof-of-concept code becomes available. Organizations worldwide that depend on FrogCMS for content management face operational and security risks until mitigations or patches are applied.

To mitigate this CSRF vulnerability in FrogCMS 0.9.5, organizations should implement the following specific measures: 1) Apply any official patches or updates from FrogCMS as soon as they become available. 2) If patches are not yet released, deploy web application firewalls (WAFs) with custom rules to detect and block suspicious POST requests to the /admin/?/page/add endpoint, especially those lacking valid CSRF tokens or originating from untrusted sources. 3) Enforce strict same-site cookie attributes (SameSite=Lax or Strict) to reduce the risk of cross-origin requests. 4) Implement or verify the presence of anti-CSRF tokens in all state-changing forms and validate these tokens server-side. 5) Restrict administrative access to trusted IP ranges or VPNs to reduce exposure. 6) Educate administrators about the risks of clicking on untrusted links while logged into the CMS. 7) Monitor logs for unusual administrative activity or requests to the vulnerable endpoint. 8) Consider temporary disabling of the vulnerable functionality if feasible until a patch is applied. These targeted actions go beyond generic advice by focusing on the specific vulnerable endpoint and the nature of the CSRF attack vector.
