CVE-2025-67531 is a critical security vulnerability classified as Remote File Inclusion (RFI) in the PHP-based web application trippleS Turitor, affecting all versions prior to 1.5.3. The vulnerability stems from improper control over the filename parameter used in PHP include or require statements, which allows an attacker to supply a crafted filename that points to a remote malicious file. When the application includes this file, it executes arbitrary PHP code controlled by the attacker. This flaw requires no authentication or user interaction, making it trivially exploitable over the network. The CVSS v3.1 base score of 9.8 reflects the vulnerability’s potential to fully compromise confidentiality, integrity, and availability of the affected system. Attackers exploiting this vulnerability can execute arbitrary commands, steal sensitive data, modify or delete files, and potentially pivot to other systems within the network. Although no public exploits are reported yet, the vulnerability’s nature and severity make it a prime target for attackers. The affected product, Turitor, is a PHP program used for content management or similar web-based functions, and the vulnerability affects all versions before 1.5.3, with no patch links currently available. The vulnerability was published on December 9, 2025, and assigned by Patchstack. Given the widespread use of PHP applications in Europe, this vulnerability poses a significant risk to organizations relying on Turitor for their web infrastructure.

For European organizations, the impact of CVE-2025-67531 can be severe. Successful exploitation can lead to complete system compromise, allowing attackers to execute arbitrary code remotely without authentication. This can result in data breaches involving sensitive personal and corporate information, disruption of critical web services, defacement of websites, and potential lateral movement within corporate networks. The high CVSS score indicates that confidentiality, integrity, and availability are all at risk. Organizations in sectors such as finance, healthcare, government, and e-commerce, which often rely on PHP-based web applications, could face significant operational and reputational damage. Additionally, compliance with GDPR and other data protection regulations could be jeopardized if personal data is exposed. The lack of known exploits currently in the wild provides a window for proactive mitigation, but the critical nature demands immediate attention to prevent exploitation by opportunistic attackers or advanced persistent threats targeting European infrastructure.

1. Immediate upgrade to trippleS Turitor version 1.5.3 or later once available to apply the official patch addressing this vulnerability. 2. Until patches are available, implement strict input validation and sanitization on all user-supplied parameters that influence file inclusion, ensuring only safe, expected filenames are processed. 3. Employ Web Application Firewalls (WAFs) with rules specifically designed to detect and block attempts to exploit Remote File Inclusion vulnerabilities, including suspicious URL patterns and payloads. 4. Disable allow_url_include and allow_url_fopen directives in PHP configurations to prevent inclusion of remote files. 5. Conduct thorough code reviews and security audits of custom PHP code to identify and remediate similar unsafe include/require usage. 6. Monitor web server and application logs for unusual requests indicative of exploitation attempts. 7. Segment and harden web servers hosting Turitor to limit potential lateral movement in case of compromise. 8. Educate development and operations teams about secure coding practices related to file inclusion and parameter handling. 9. Prepare incident response plans specifically addressing web application compromise scenarios.
