CVE-2025-58206 is a high-severity vulnerability classified under CWE-98, which pertains to improper control of filenames used in include or require statements within PHP programs. Specifically, this vulnerability affects the ThemeMove MaxCoach product, versions up to and including 3.2.5. The issue is a Remote File Inclusion (RFI) vulnerability, allowing an attacker to manipulate the filename parameter used in PHP's include or require functions. This can lead to the inclusion and execution of arbitrary remote files, resulting in remote code execution (RCE). The vulnerability is exploitable remotely without authentication or user interaction, as indicated by the CVSS vector (AV:N/AC:H/PR:N/UI:N). Although the attack complexity is high, the impact on confidentiality, integrity, and availability is critical, with a CVSS score of 8.1. Exploiting this vulnerability could allow attackers to execute arbitrary PHP code on the server, potentially leading to full system compromise, data theft, defacement, or use of the server as a pivot point for further attacks. The vulnerability arises from insufficient validation or sanitization of user-supplied input used in file inclusion statements, a common security flaw in PHP applications. No patches or fixes are currently linked, and no known exploits have been reported in the wild as of the publication date (September 5, 2025). However, the presence of such a vulnerability in a widely used WordPress theme or PHP-based LMS (Learning Management System) like MaxCoach could attract attackers once public disclosure occurs.

For European organizations, the impact of this vulnerability can be significant, especially for educational institutions, e-learning providers, and businesses using the MaxCoach theme for their websites or learning platforms. Successful exploitation could lead to unauthorized access to sensitive data, including personal information of students or employees, intellectual property, and internal communications. The ability to execute arbitrary code remotely could disrupt service availability, leading to downtime and reputational damage. Given the high confidentiality, integrity, and availability impact, organizations may face regulatory consequences under GDPR if personal data is compromised. Additionally, attackers could leverage compromised systems to launch further attacks within the network or use them as part of botnets, increasing the overall threat landscape in Europe.

Organizations using the MaxCoach theme should immediately verify their version and upgrade to a patched version once available from ThemeMove. In the absence of an official patch, temporary mitigations include disabling or restricting the use of dynamic include or require statements in PHP code, particularly those that accept user input. Implementing a Web Application Firewall (WAF) with rules to detect and block suspicious file inclusion attempts can provide interim protection. Conduct thorough input validation and sanitization to ensure that only allowed filenames or paths are processed. Restrict PHP's allow_url_include directive to 'Off' to prevent remote file inclusion. Regularly audit and monitor web server logs for unusual requests indicative of exploitation attempts. Additionally, isolate the web server environment using containerization or sandboxing to limit the impact of potential compromises. Finally, maintain up-to-date backups and have an incident response plan ready to address any exploitation.
