CVE-2025-68540 is a critical remote file inclusion vulnerability found in the thembay Fana PHP program, affecting all versions up to and including 1.1.35. The vulnerability stems from improper control over the filename parameter used in PHP's include or require statements, which allows an attacker to supply a remote file path. When exploited, this enables the attacker to execute arbitrary PHP code on the target server by including malicious remote files. The vulnerability does not require any authentication or user interaction, making it highly exploitable over the network. The CVSS v3.1 base score of 9.8 reflects the vulnerability's ease of exploitation (network vector, low attack complexity), and its severe impact on confidentiality, integrity, and availability. Although no public exploits are currently reported, the nature of remote file inclusion vulnerabilities historically leads to rapid exploitation once disclosed. The vulnerability affects web applications using the Fana product, which is a PHP-based program likely used in content management or e-commerce contexts. The lack of patch links suggests that a fix may not yet be publicly available, increasing the urgency for organizations to implement interim mitigations. Attackers exploiting this flaw can gain full control over the affected system, potentially leading to data theft, website defacement, malware deployment, or pivoting to internal networks.

For European organizations, exploitation of CVE-2025-68540 could result in severe consequences including unauthorized access to sensitive data, complete system compromise, and disruption of business operations. Given the criticality of the vulnerability and the fact it requires no authentication, attackers can remotely execute arbitrary code, leading to data breaches or ransomware deployment. Organizations relying on the thembay Fana product for web services risk exposure of customer data, intellectual property, and operational downtime. The impact extends to reputational damage and regulatory penalties under GDPR if personal data is compromised. Additionally, compromised systems can be used as launchpads for further attacks within corporate networks or against third parties. The vulnerability's presence in PHP-based web applications, which are widely used across Europe, amplifies the potential scale of impact. Industries such as e-commerce, media, and public sector entities using Fana or similar PHP programs are particularly vulnerable.

1. Immediate action should be taken to monitor for any updates or patches released by thembay for the Fana product and apply them promptly. 2. Until patches are available, implement strict input validation and sanitization on all parameters that influence file inclusion to prevent injection of remote paths. 3. Employ web application firewalls (WAFs) with rules designed to detect and block remote file inclusion attempts. 4. Disable allow_url_include and allow_url_fopen directives in PHP configurations to prevent remote file inclusion via URL. 5. Conduct thorough code reviews to identify and remediate unsafe include/require statements that do not properly validate input. 6. Restrict web server permissions to limit the impact of any successful exploitation, such as running PHP processes with least privilege. 7. Monitor logs for suspicious requests that attempt to exploit file inclusion vectors. 8. Educate development teams on secure coding practices related to file inclusion and input handling. 9. Consider network segmentation to isolate web servers running vulnerable applications from critical internal systems. 10. Prepare incident response plans to quickly contain and remediate any exploitation attempts.
