CVE-2025-64205 is a vulnerability classified as Improper Control of Filename for Include/Require Statement in PHP programs, specifically impacting the TieLabs Jannah product up to version 7.6.0. The vulnerability is a Remote File Inclusion (RFI) flaw, which occurs when the application fails to properly validate or sanitize user-supplied input used in PHP include or require statements. This allows an attacker to supply a malicious remote file path that the server will include and execute as PHP code. The consequence of this vulnerability is potentially severe, as it can lead to remote code execution on the affected server, enabling attackers to execute arbitrary commands, steal sensitive data, modify website content, or pivot to other internal systems. The vulnerability does not require authentication or user interaction, increasing its risk profile. Although no known exploits are publicly reported at this time, the flaw is publicly disclosed and documented in the CVE database, indicating that attackers could develop exploits. The vulnerability affects all versions of Jannah up to and including 7.6.0, with no patch links currently available, suggesting that mitigation relies on configuration changes and input validation until an official patch is released. The vulnerability is particularly relevant for websites and applications using Jannah as a CMS or theme framework, which are often deployed in PHP environments. The lack of a CVSS score necessitates an expert severity assessment based on impact and exploitability factors.

For European organizations, the impact of CVE-2025-64205 can be substantial. Organizations using the Jannah product for web content management or digital publishing could face complete system compromise if exploited. This includes unauthorized access to sensitive customer data, intellectual property theft, defacement of websites, and disruption of services. The vulnerability could also be leveraged as a foothold for lateral movement within corporate networks, increasing the risk of broader cyberattacks. Given the widespread use of PHP-based CMS solutions in Europe, especially in sectors such as media, education, and e-commerce, the potential attack surface is significant. The impact on confidentiality, integrity, and availability is high, as attackers can execute arbitrary code remotely without authentication. This could lead to regulatory compliance issues under GDPR if personal data is exposed or altered. Additionally, reputational damage and financial losses due to downtime or remediation costs are likely. The absence of known exploits currently provides a window for proactive defense, but the risk remains urgent.

To mitigate CVE-2025-64205, European organizations should implement the following specific measures: 1) Immediately audit all Jannah installations to identify affected versions and isolate vulnerable systems. 2) Apply official patches or updates from TieLabs as soon as they become available. 3) In the interim, disable PHP's allow_url_include directive to prevent remote file inclusion via configuration (php.ini: allow_url_include=Off). 4) Implement strict input validation and sanitization on all user inputs that influence file inclusion logic, using whitelisting approaches to restrict allowed filenames or paths. 5) Employ Web Application Firewalls (WAFs) with rules designed to detect and block suspicious include/require patterns and remote file inclusion attempts. 6) Conduct regular code reviews and security testing to identify and remediate similar insecure coding practices. 7) Monitor web server and application logs for unusual requests or errors indicative of exploitation attempts. 8) Educate developers and administrators about secure PHP coding practices and the risks of dynamic file inclusion. These steps go beyond generic advice by focusing on configuration hardening, proactive detection, and secure coding tailored to the nature of this vulnerability.
