CVE-2025-67531 is a vulnerability classified as Improper Control of Filename for Include/Require Statement in the PHP-based product trippleS Turitor, affecting versions prior to 1.5.3. This vulnerability allows an attacker to perform Remote File Inclusion (RFI) or Local File Inclusion (LFI) by manipulating the filename parameter used in PHP's include or require statements without proper validation or sanitization. The core issue is that the application fails to restrict or validate user-supplied input that determines which files are included during runtime, enabling attackers to inject malicious file paths. Exploiting this vulnerability can lead to arbitrary code execution on the server, unauthorized disclosure of sensitive files, or complete system compromise. The vulnerability does not require authentication, increasing its risk profile. While no public exploits have been reported yet, the nature of RFI/LFI vulnerabilities makes them attractive targets for attackers aiming to gain initial access or escalate privileges. The lack of a CVSS score suggests this is a newly published vulnerability, but its characteristics align with high-severity web application security issues. The vulnerability affects web servers running PHP with the Turitor application, commonly used in educational or content management contexts, which may be deployed in various organizational environments.

For European organizations, the impact of CVE-2025-67531 can be severe. Exploitation could lead to unauthorized remote code execution, allowing attackers to take control of affected servers, steal sensitive data, or disrupt services. This is particularly critical for organizations hosting sensitive information or providing public-facing web services. The vulnerability could be leveraged to deploy malware, ransomware, or pivot to internal networks, increasing the risk of widespread compromise. Given the PHP-based nature of the vulnerability, organizations relying on PHP web applications or content management systems similar to Turitor are at higher risk. The absence of authentication requirements and the ease of exploitation amplify the threat, potentially affecting confidentiality, integrity, and availability of systems. Additionally, regulatory compliance frameworks in Europe, such as GDPR, impose strict data protection requirements, and exploitation could lead to significant legal and financial consequences.

To mitigate CVE-2025-67531, organizations should immediately upgrade trippleS Turitor to version 1.5.3 or later where the vulnerability is patched. If upgrading is not immediately possible, implement strict input validation and sanitization on all parameters that influence file inclusion, ensuring only allowed filenames or paths are accepted. Employ web application firewalls (WAFs) with rules designed to detect and block RFI/LFI attack patterns. Disable remote file inclusion capabilities in PHP configurations by setting 'allow_url_include' to 'Off' and 'allow_url_fopen' to 'Off' where feasible. Conduct thorough code reviews and penetration testing focused on file inclusion vectors. Monitor web server logs for suspicious requests attempting to exploit file inclusion. Additionally, isolate the Turitor application environment to limit potential lateral movement in case of compromise. Maintain regular backups and incident response plans tailored to web application attacks.
