CVE-2024-42628 is a Cross-Site Request Forgery (CSRF) vulnerability identified in FrogCMS version 0.9.5, a lightweight content management system. The vulnerability exists in the administrative snippet editing interface accessible via the /admin/?/snippet/edit/3 URL. CSRF vulnerabilities allow attackers to induce authenticated users, typically administrators, to unknowingly execute unwanted actions on the web application. In this case, an attacker can craft malicious web requests that, when visited by an authenticated admin, can modify or inject snippets without their consent. The CVSS 3.1 score of 8.8 indicates a high-severity issue with network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), but requiring user interaction (UI:R). The impact metrics show complete compromise of confidentiality, integrity, and availability (C:H/I:H/A:H), meaning an attacker could fully control the CMS content and potentially disrupt service. No patches or fixes have been published yet, and no active exploits are known, but the vulnerability is publicly disclosed and should be considered critical. The CWE-352 classification confirms this is a classic CSRF flaw, typically mitigated by anti-CSRF tokens or same-site cookie attributes. The vulnerability affects all installations running FrogCMS 0.9.5 that have the snippet editing feature enabled and accessible to administrators.

If exploited, this vulnerability could allow attackers to perform unauthorized administrative actions on FrogCMS installations, including modifying website content, injecting malicious code, or disrupting service availability. This can lead to data breaches, defacement, or complete takeover of the CMS environment. Organizations relying on FrogCMS for their web presence could suffer reputational damage, loss of customer trust, and potential regulatory penalties if sensitive data is exposed. Since the vulnerability requires only that an administrator be tricked into visiting a malicious page, social engineering attacks could be effective. The broad impact on confidentiality, integrity, and availability makes this a critical risk for any organization using the affected CMS version, especially those with public-facing websites or sensitive content.

Until an official patch is released, organizations should implement strict mitigations to reduce risk. These include enforcing multi-factor authentication for administrative access to reduce the risk of compromised credentials being exploited. Administrators should be trained to avoid clicking on suspicious links or visiting untrusted websites while logged into the CMS. Implementing web application firewalls (WAFs) with custom rules to detect and block suspicious POST requests to the snippet editing endpoint can help mitigate exploitation attempts. Additionally, administrators can restrict access to the /admin/ interface by IP whitelisting or VPN-only access to limit exposure. Reviewing and applying HTTP security headers such as SameSite=strict on session cookies can reduce CSRF risks. Monitoring logs for unusual administrative activity and preparing incident response plans are recommended. Once patches become available, prompt application is critical.
