CVE-2025-56435 is a SQL Injection vulnerability identified in FoxCMS version 1.2.6 and earlier. The vulnerability exists in the /DataBackup.php file, specifically in the handling of the 'id' parameter. An attacker can exploit this flaw by injecting malicious SQL code through the 'id' parameter, which is not properly sanitized or validated. This allows the attacker to manipulate the backend database queries executed by the CMS. The consequence of this injection can be severe, potentially enabling the execution of arbitrary code on the server hosting FoxCMS. This could lead to unauthorized data access, data modification, or complete system compromise. The vulnerability is remotely exploitable, meaning no local access or authentication is required, and it does not require user interaction. No CVSS score has been assigned yet, and there are no known exploits in the wild at the time of publication. The lack of patch links suggests that a fix may not yet be publicly available, increasing the urgency for affected organizations to apply mitigations or monitor for updates. FoxCMS is a content management system, and such vulnerabilities can be particularly impactful as they often run on web servers exposed to the internet, making them attractive targets for attackers seeking to compromise websites or pivot into internal networks.

For European organizations using FoxCMS, this vulnerability poses a significant risk. Exploitation could lead to unauthorized access to sensitive data, including customer information, intellectual property, or internal business data. The ability to execute arbitrary code could allow attackers to implant malware, ransomware, or establish persistent backdoors, severely impacting confidentiality, integrity, and availability of affected systems. Given the web-facing nature of CMS platforms, successful exploitation could also damage organizational reputation and lead to regulatory non-compliance, especially under GDPR requirements for data protection and breach notification. The absence of a patch and public exploits means organizations must be vigilant to prevent exploitation attempts. The impact is heightened for sectors with high-value data or critical online services, such as e-commerce, government portals, and media companies.

Organizations should immediately audit their environments to identify any instances of FoxCMS version 1.2.6 or earlier. If found, they should isolate affected systems from public access until a patch or official fix is available. In the interim, applying web application firewall (WAF) rules to detect and block SQL injection patterns targeting the 'id' parameter in /DataBackup.php can reduce risk. Input validation and parameterized queries should be implemented if organizations maintain or customize FoxCMS code. Monitoring web server logs for suspicious requests targeting /DataBackup.php and unusual database query patterns is critical for early detection. Organizations should also prepare incident response plans specific to web application compromises. Engaging with FoxCMS developers or community for updates and patches is recommended. Finally, regular backups and ensuring they are stored securely offline can mitigate damage from potential exploitation.
