CVE-2025-60202 is a Remote File Inclusion (RFI) vulnerability found in the Kyle Phillips Favorites PHP application, affecting versions up to and including 2.3.6. The root cause is improper control over the filename parameter used in PHP include or require statements, which allows an attacker to specify a remote file to be included and executed by the server. This vulnerability does not require authentication or user interaction and can be exploited remotely over the network. Successful exploitation can lead to disclosure of sensitive information, as the attacker can include arbitrary files, or potentially execute arbitrary PHP code if the remote file contains malicious code. The CVSS v3.1 base score of 7.5 reflects high severity, with attack vector being network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), unchanged scope (S:U), high confidentiality impact (C:H), no integrity or availability impact (I:N/A:N). Although no public exploits are currently known, the vulnerability is critical due to its ease of exploitation and potential impact. The vulnerability affects web servers running the vulnerable PHP application, which is commonly used in web environments. The lack of available patches at the time of publication necessitates immediate mitigation steps to prevent exploitation.

For European organizations, this vulnerability could lead to significant confidentiality breaches, exposing sensitive customer data, internal files, or configuration details. Attackers could leverage this flaw to execute arbitrary code remotely, potentially gaining further access to internal networks or pivoting to other systems. This could disrupt business operations, damage reputation, and lead to regulatory penalties under GDPR if personal data is compromised. Organizations relying on the Kyle Phillips Favorites plugin in their web infrastructure, especially those in sectors like e-commerce, finance, or government services, are at heightened risk. The vulnerability's network accessibility and lack of required privileges make it a prime target for automated scanning and exploitation attempts. Without timely mitigation, European entities could face data loss, unauthorized access, and service interruptions.

1. Immediately monitor for updates or patches from the vendor Kyle Phillips and apply them as soon as they become available. 2. In the interim, disable or remove the vulnerable Favorites plugin from web servers if feasible. 3. Implement strict input validation and sanitization on all parameters that influence file inclusion to prevent injection of remote URLs or unauthorized file paths. 4. Configure PHP settings to disable remote file inclusion by setting 'allow_url_include=Off' and 'allow_url_fopen=Off' in php.ini. 5. Employ web application firewalls (WAFs) with rules designed to detect and block attempts to exploit file inclusion vulnerabilities. 6. Conduct regular security audits and code reviews to identify similar vulnerabilities in custom or third-party PHP code. 7. Restrict web server permissions to limit the impact of any successful exploitation, ensuring the web server runs with minimal privileges. 8. Monitor logs for suspicious requests that attempt to include remote files or unusual URL parameters.
