CVE-2025-50692 is a vulnerability identified in FoxCMS versions up to and including 1.2.5. The vulnerability exists in the admin interface, specifically within the template_file/editFile.html component. This flaw allows for remote code execution (RCE), meaning an attacker who can access this administrative interface could execute arbitrary code on the server hosting FoxCMS. The vulnerability likely arises from insufficient input validation or improper handling of template files during editing, which enables malicious payloads to be injected and executed. Since the vulnerability is located in an administrative template editing page, exploitation requires access to the admin panel, either through stolen credentials, weak authentication, or other means. No CVSS score has been assigned yet, and no known exploits have been reported in the wild as of the publication date. The lack of patch links suggests that a fix may not yet be publicly available or that the vendor has not released an official update. FoxCMS is a content management system, and such vulnerabilities can lead to full system compromise, data theft, defacement, or use of the server as a pivot point for further attacks.

For European organizations using FoxCMS, this vulnerability poses a significant risk. If exploited, attackers could gain full control over the CMS server, leading to unauthorized data access, data manipulation, or service disruption. This could affect confidentiality, integrity, and availability of the hosted websites or applications. Organizations in sectors such as government, finance, healthcare, and media, which rely on CMS platforms for public-facing or internal content management, could face reputational damage, regulatory penalties (e.g., GDPR violations), and operational downtime. The requirement for admin panel access limits the attack surface but does not eliminate risk, especially if credential hygiene is poor or if other vulnerabilities enable privilege escalation. The absence of known exploits in the wild provides a window for proactive mitigation, but the potential for rapid exploitation once a public exploit emerges is high. Additionally, the lack of an official patch increases the urgency for organizations to implement compensating controls.

1. Immediately restrict access to the FoxCMS admin interface by IP whitelisting or VPN-only access to reduce exposure. 2. Enforce strong, unique passwords and implement multi-factor authentication (MFA) for all admin accounts to prevent unauthorized access. 3. Monitor admin access logs for unusual activity or login attempts. 4. If possible, temporarily disable the template editing functionality until a patch is available. 5. Conduct a thorough audit of user privileges to ensure only necessary personnel have admin rights. 6. Implement web application firewalls (WAF) with custom rules to detect and block suspicious payloads targeting the template_file/editFile.html endpoint. 7. Regularly back up CMS data and server configurations to enable rapid recovery in case of compromise. 8. Stay alert for vendor announcements or community patches addressing this vulnerability and apply updates promptly once available. 9. Consider isolating the CMS environment from critical internal networks to limit lateral movement in case of exploitation.
