CVE-2025-67925 identifies a remote file inclusion (RFI) vulnerability in the PHP-based Corpkit product by zozothemes, affecting versions up to 2.0. The vulnerability arises from improper control of filenames used in PHP include or require statements, allowing an attacker to specify external files to be included and executed by the server. This can lead to remote code execution, enabling attackers to run arbitrary PHP code, potentially leading to full system compromise. The CVSS v3.1 score is 8.1, indicating high severity, with attack vector network (AV:N), high attack complexity (AC:H), no privileges required (PR:N), no user interaction (UI:N), and impacts on confidentiality, integrity, and availability (C:H/I:H/A:H). The vulnerability does not require authentication, making it exploitable remotely by unauthenticated attackers. Although no public exploits are currently known, the nature of RFI vulnerabilities historically leads to rapid exploitation once disclosed. The vulnerability affects the Corpkit CMS, which is used for website and content management, often deployed in web hosting environments. The lack of patch links suggests that fixes may not yet be publicly available, emphasizing the need for immediate mitigation steps. Proper input validation, disabling allow_url_include in PHP configurations, and monitoring for suspicious file inclusion attempts are critical defensive measures.

For European organizations, this vulnerability poses a significant risk to web infrastructure relying on the Corpkit CMS. Successful exploitation can lead to unauthorized access, data theft, website defacement, and potential pivoting to internal networks. The compromise of web servers can disrupt business operations, damage reputation, and lead to regulatory non-compliance, especially under GDPR due to potential data breaches. Organizations in sectors such as e-commerce, media, and public services using Corpkit are particularly vulnerable. The high severity and remote exploitability mean attackers can operate without insider access or user interaction, increasing the threat landscape. Additionally, the potential for widespread impact exists if attackers leverage this vulnerability to deploy malware or ransomware. The absence of known exploits currently provides a window for proactive defense, but the risk of rapid exploitation post-disclosure remains high.

1. Immediately audit all Corpkit installations to identify affected versions (<= 2.0). 2. Apply vendor patches or updates as soon as they become available; monitor zozothemes announcements and security advisories closely. 3. In the interim, disable PHP's allow_url_include directive to prevent remote file inclusion. 4. Implement strict input validation and sanitization on all user-supplied parameters that influence file inclusion 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 security scans and penetration tests focusing on file inclusion vulnerabilities. 7. Restrict web server permissions to limit the impact of potential code execution. 8. Monitor logs for unusual file access or inclusion activities. 9. Educate development teams on secure coding practices to prevent similar vulnerabilities. 10. Consider isolating Corpkit instances in segmented network zones to contain potential breaches.
