CVE-2025-68983 is a vulnerability classified as Improper Control of Filename for Include/Require Statement in the thembay Greenmart PHP application, specifically a Remote File Inclusion (RFI) flaw. This vulnerability occurs when the application fails to properly validate or sanitize user-supplied input used in PHP include or require statements. As a result, an attacker can manipulate the filename parameter to include arbitrary files from remote servers or local system files. This can lead to execution of malicious PHP code, unauthorized disclosure of sensitive data, or complete compromise of the web server hosting Greenmart. The affected versions include all Greenmart releases up to and including 4.2.11. The vulnerability was published on December 30, 2025, and no CVSS score has been assigned yet. No public exploits have been reported, but the nature of RFI vulnerabilities makes them attractive targets for attackers due to their potential for remote code execution without authentication. The vulnerability is particularly dangerous in web-facing e-commerce platforms like Greenmart, which often handle sensitive customer and transaction data. The lack of patch links indicates that a fix may not yet be publicly available, increasing the urgency for organizations to implement interim mitigations.

For European organizations, exploitation of CVE-2025-68983 could result in severe consequences including unauthorized access to sensitive customer data, theft of payment information, defacement of websites, or full server takeover. This could lead to financial losses, reputational damage, and regulatory penalties under GDPR due to data breaches. E-commerce platforms like Greenmart are critical infrastructure for many businesses, and disruption or compromise can halt operations and erode customer trust. The vulnerability’s ability to allow remote code execution without authentication means attackers can operate stealthily and at scale. Additionally, compromised servers could be used as pivot points for further attacks within corporate networks or for launching attacks against other targets. The absence of known exploits currently provides a window for proactive defense, but the risk remains high given the widespread use of PHP-based e-commerce solutions in Europe.

Organizations should immediately inventory their use of the thembay Greenmart product and identify affected versions (<= 4.2.11). Until an official patch is released, apply the following mitigations: 1) Restrict PHP include paths using open_basedir to limit file inclusion to trusted directories. 2) Implement strict input validation and sanitization on any parameters used in include/require statements to prevent injection of malicious filenames. 3) Deploy Web Application Firewalls (WAFs) configured to detect and block RFI attack patterns, such as suspicious URL parameters or remote file references. 4) Disable allow_url_include and allow_url_fopen in PHP configuration to prevent remote file inclusion. 5) Monitor web server logs for unusual requests or errors related to file inclusion. 6) Prepare to apply vendor patches as soon as they become available and test updates in a controlled environment before deployment. 7) Educate development teams on secure coding practices to avoid similar vulnerabilities in custom code.
