CVE-2024-46085 identifies a Cross-Site Request Forgery (CSRF) vulnerability in FrogCMS version 0.9.5, specifically targeting the file rename functionality accessible via the /admin/?/plugin/file_manager/rename endpoint. CSRF vulnerabilities occur when a web application does not adequately verify that requests modifying state originate from legitimate users, allowing attackers to craft malicious requests that execute with the privileges of an authenticated user. In this case, an attacker can induce an authenticated administrator to unknowingly rename files within the CMS, potentially altering or replacing critical files. This can lead to unauthorized changes in website content, defacement, or insertion of malicious code, severely impacting the confidentiality, integrity, and availability of the CMS and hosted content. The CVSS 3.1 base score of 8.8 reflects the network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), but requiring user interaction (UI:R). The scope is unchanged (S:U), but the impact on confidentiality, integrity, and availability is high (C:H/I:H/A:H). No patches or mitigations have been officially published yet, and no known exploits are reported in the wild, but the vulnerability poses a significant risk due to the administrative level impact and ease of exploitation once user interaction occurs.

If exploited, this vulnerability can lead to unauthorized administrative actions such as renaming critical files, which may disrupt website functionality, cause data loss, or enable further exploitation such as code injection or privilege escalation. The high impact on confidentiality, integrity, and availability means attackers could manipulate website content, deface pages, or introduce backdoors. Organizations relying on FrogCMS 0.9.5 for content management are at risk of operational disruption and reputational damage. Since the vulnerability requires an authenticated administrator to be tricked into performing the action, social engineering or phishing campaigns could be used to facilitate exploitation. The absence of patches increases the window of exposure, and attackers may develop exploits given the public disclosure. This threat is particularly critical for organizations with public-facing websites managed via FrogCMS, especially those lacking multi-factor authentication or other compensating controls.

Organizations should immediately review and restrict access to the FrogCMS administrative interface, limiting it to trusted networks and users. Implementing strict Content Security Policy (CSP) headers and SameSite cookies can help reduce CSRF attack vectors. Administrators should be trained to recognize phishing attempts and avoid clicking on suspicious links while authenticated. Employing web application firewalls (WAFs) with custom rules to detect and block suspicious POST requests to the /admin/?/plugin/file_manager/rename endpoint can provide temporary protection. Monitoring logs for unusual rename operations or access patterns is critical. Where possible, upgrading to a patched version of FrogCMS once available is essential. In the interim, disabling or restricting the vulnerable plugin or functionality may be necessary. Additionally, enforcing multi-factor authentication (MFA) for administrative access can reduce the risk of account compromise facilitating exploitation.
