CVE-2024-42625 identifies a Cross-Site Request Forgery (CSRF) vulnerability in FrogCMS version 0.9.5, specifically targeting the administrative endpoint /admin/?/layout/add. CSRF vulnerabilities allow attackers to trick authenticated users into submitting unwanted requests to a web application, potentially causing unauthorized actions without the user's consent. In this case, the vulnerability could enable an attacker to manipulate layout configurations within the CMS if the victim is an authenticated administrator who interacts with a maliciously crafted web page. The CVSS 3.1 base score is 5.4 (medium), with vector AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N, indicating network attack vector, low attack complexity, requiring privileges and user interaction, with a scope change and limited confidentiality and integrity impacts but no availability impact. The vulnerability is classified under CWE-352, which covers CSRF issues. No patches or known exploits are currently available, but the vulnerability's presence in a CMS used for website management poses a risk of unauthorized content or layout modifications, potentially undermining site integrity and trust. The scope change (S:C) suggests that exploitation could affect resources beyond the vulnerable component, possibly impacting other parts of the CMS or hosted content. Organizations using FrogCMS 0.9.5 should be aware of this vulnerability and prepare to implement mitigations or patches once available.

The primary impact of CVE-2024-42625 is on the integrity and confidentiality of web content managed through FrogCMS. An attacker exploiting this CSRF vulnerability could cause unauthorized changes to website layouts, potentially defacing sites, injecting misleading content, or disrupting user experience. Although availability is not directly affected, the reputational damage and trust erosion from unauthorized content changes can be significant. Since exploitation requires authenticated administrator privileges and user interaction, the attack surface is limited to users with elevated access who might be tricked into visiting malicious sites. Organizations relying on FrogCMS for critical web presence or customer-facing portals could face operational disruptions and brand damage. The scope change indicates that the impact might extend beyond the immediate vulnerable endpoint, affecting other CMS components or data. Given no known exploits in the wild, the immediate risk is moderate, but the vulnerability should be addressed promptly to prevent future exploitation as proof-of-concept or exploit code may emerge.

To mitigate CVE-2024-42625, organizations should implement robust CSRF protections in FrogCMS, including the use of anti-CSRF tokens embedded in forms and verified on the server side for all state-changing requests, especially administrative actions like layout modifications. Validating the HTTP Referer or Origin headers can provide additional assurance that requests originate from trusted sources. Restricting administrative interface access through network controls, such as VPNs or IP whitelisting, reduces exposure to external attackers. Enforcing multi-factor authentication (MFA) for administrator accounts can limit the risk of compromised credentials being exploited. Regularly monitoring administrative logs for unusual or unauthorized changes can help detect exploitation attempts early. Until an official patch is released, consider applying web application firewall (WAF) rules to detect and block suspicious CSRF attempts targeting the /admin/?/layout/add endpoint. Educating administrators about the risks of interacting with untrusted websites while logged into the CMS can reduce the likelihood of successful social engineering attacks. Finally, maintain up-to-date backups of website configurations and content to enable rapid recovery if unauthorized changes occur.
