CVE-2025-12550 is a critical vulnerability identified in the jwsthemes OchaHouse product, a PHP-based content management system or theme framework. The vulnerability stems from improper control of filenames used in PHP include or require statements, enabling remote file inclusion (RFI). This means an attacker can manipulate the input that determines which file is included by the PHP script, potentially causing the server to execute malicious code hosted remotely. The affected versions include all up to and including 2.2.8. The vulnerability does not require any authentication or user interaction, making it trivially exploitable remotely over the network. Exploiting this flaw allows attackers to execute arbitrary PHP code, leading to full compromise of the web server, including data theft, defacement, installation of backdoors, or pivoting to internal networks. The CVSS v3.1 base score of 9.8 reflects the high impact on confidentiality, integrity, and availability, combined with ease of exploitation. No known public exploits have been reported yet, but the vulnerability's nature and severity make it a prime target for attackers once exploit code becomes available. The lack of available patches at the time of reporting increases the urgency for mitigation through configuration hardening and monitoring. This vulnerability is particularly relevant for organizations relying on OchaHouse for website management, especially those in Europe where PHP-based CMS solutions are widely used.

The impact on European organizations can be severe. Successful exploitation can lead to complete compromise of affected web servers, resulting in unauthorized access to sensitive data, including personal data protected under GDPR. Attackers could deface websites, disrupt services, or use compromised servers as a foothold for further attacks within corporate networks. This can damage organizational reputation, lead to regulatory penalties, and cause operational downtime. Sectors such as government, finance, healthcare, and e-commerce, which often use PHP-based CMS platforms, are particularly at risk. The vulnerability's remote exploitability without authentication increases the likelihood of automated scanning and exploitation attempts, potentially leading to widespread incidents if not addressed promptly. Additionally, compromised servers could be used to launch attacks against other European infrastructure, amplifying the threat.

1. Apply official patches from jwsthemes as soon as they are released to address CVE-2025-12550. 2. Until patches are available, implement strict input validation and sanitization on all parameters controlling file inclusion paths to prevent injection of remote URLs or arbitrary file paths. 3. Configure PHP settings to disable allow_url_include and allow_url_fopen to prevent remote file inclusion. 4. Employ web application firewalls (WAFs) with rules specifically designed to detect and block RFI attempts targeting OchaHouse or similar PHP applications. 5. Restrict file inclusion to a whitelist of trusted directories using PHP’s open_basedir directive. 6. Monitor web server logs for unusual requests or attempts to include remote files. 7. Conduct regular security audits and vulnerability scans focusing on PHP applications and their configurations. 8. Educate development and operations teams about secure coding practices related to file inclusion and input handling.
