CVE-2024-42623 identifies a Cross-Site Request Forgery (CSRF) vulnerability in FrogCMS version 0.9.5, specifically targeting the administrative endpoint /admin/?/layout/delete/1. CSRF vulnerabilities allow attackers to induce authenticated users, typically administrators, to unknowingly execute unwanted actions on a web application. In this case, the vulnerability permits an attacker to craft malicious requests that, when visited by an authenticated admin, can delete layout elements or perform other administrative functions without consent. The CVSS 3.1 base score of 8.8 reflects the high impact and ease of exploitation: the attack vector is network-based (AV:N), requires no privileges (PR:N), but does require user interaction (UI:R). The scope is unchanged (S:U), but the impact on confidentiality (C:H), integrity (I:H), and availability (A:H) is high, indicating potential full compromise of the CMS data and functionality. No patches or fixes have been published yet, and no known exploits are in the wild, but the vulnerability is critical due to the sensitive nature of administrative actions it exposes. The underlying weakness corresponds to CWE-352, which is a common web security flaw where anti-CSRF tokens or other protections are missing or improperly implemented.

The impact of CVE-2024-42623 is significant for organizations using FrogCMS 0.9.5, especially those with publicly accessible administrative interfaces. An attacker can exploit this vulnerability to perform unauthorized administrative actions such as deleting layouts or modifying site structure, potentially leading to website defacement, data loss, or disruption of services. The compromise of confidentiality, integrity, and availability can result in loss of trust, reputational damage, and operational downtime. Since the vulnerability requires user interaction but no authentication, phishing or social engineering campaigns could be used to lure administrators into triggering the exploit. This risk is particularly acute for organizations that do not employ additional layers of security such as IP restrictions, multi-factor authentication, or web application firewalls. The absence of patches increases the window of exposure, making proactive mitigation essential.

To mitigate CVE-2024-42623, organizations should immediately restrict access to the FrogCMS administrative interface using network-level controls such as VPNs, IP whitelisting, or firewall rules to limit exposure to trusted users only. Implementing multi-factor authentication (MFA) for admin accounts can reduce the risk of unauthorized access. Administrators should be trained to recognize and avoid phishing attempts that could trigger CSRF attacks. Employing web application firewalls (WAFs) with rules to detect and block CSRF attack patterns can provide an additional layer of defense. Until an official patch is released, consider disabling or restricting the vulnerable endpoint (/admin/?/layout/delete/1) if feasible. Monitoring administrative actions and logs for unusual activity can help detect exploitation attempts early. Finally, maintain regular backups of website data and configurations to enable recovery in case of compromise.
