CVE-2025-62029 is a remote file inclusion vulnerability found in the themesion Grevo PHP program, specifically affecting versions up to 2.4. The root cause is improper control over the filename parameter used in PHP's include or require statements, which allows an attacker to specify a remote file to be included and executed by the server. This vulnerability enables unauthenticated remote attackers to execute arbitrary PHP code on the target system, potentially leading to full system compromise. The vulnerability does not require user interaction or authentication, and the attack vector is network-based, making it exploitable over the internet. The CVSS v3.1 score of 8.1 reflects high impact on confidentiality, integrity, and availability, with a high attack complexity but no privileges or user interaction required. Although no known exploits are currently reported in the wild, the vulnerability is critical due to the potential for remote code execution. The affected product, Grevo, is a PHP-based theme or framework used in web applications, and improper input validation or sanitization of include paths is the primary cause. Without proper patching or mitigation, attackers can leverage this flaw to deploy web shells, steal sensitive data, deface websites, or pivot within the network.

For European organizations, the impact of CVE-2025-62029 can be severe. Exploitation can lead to unauthorized remote code execution, allowing attackers to gain control over web servers hosting Grevo-based applications. This can result in data breaches involving personal and financial information, disruption of services through defacement or denial of service, and potential lateral movement within corporate networks. Organizations in sectors such as e-commerce, government, and media that rely on PHP-based web applications are particularly vulnerable. The compromise of web servers can also damage organizational reputation and lead to regulatory penalties under GDPR if personal data is exposed. Given the vulnerability's network accessibility and lack of required authentication, attackers can easily target exposed web servers. The absence of known exploits in the wild currently provides a window for proactive mitigation, but the risk of future exploitation remains high.

1. Monitor official channels from themesion for patches addressing CVE-2025-62029 and apply them immediately upon release. 2. Until patches are available, implement web application firewall (WAF) rules to detect and block suspicious include/require requests or attempts to inject remote file paths. 3. Restrict PHP configuration settings such as 'allow_url_include' to 'Off' to prevent inclusion of remote files. 4. Employ strict input validation and sanitization on all parameters that influence file inclusion to ensure only trusted, local files are referenced. 5. Use PHP open_basedir restrictions to limit the directories accessible for file inclusion. 6. Conduct thorough code reviews and penetration testing focused on file inclusion vectors in Grevo-based applications. 7. Monitor server logs for unusual requests or errors related to file inclusion attempts. 8. Educate development teams on secure coding practices to avoid similar vulnerabilities in the future.
