How the Exploit Works
The vulnerability lies in the ‘start_restore’ function in the 1 Click WordPress Migration Plugin. This function does not perform a proper capability check, which allows an attacker with Subscriber-level access to upload arbitrary files to the server. By crafting and uploading a malicious file, the attacker could potentially execute arbitrary code remotely, gaining unauthorized control over the system or causing data leakage.
Conceptual Example Code
Below is a conceptual example of a HTTP POST request an attacker might use to exploit this vulnerability:
POST /wp-admin/admin-ajax.php?action=1_click_wp_restore HTTP/1.1
Host: vulnerable-website.com
Content-Type: multipart/form-data
--boundary
Content-Disposition: form-data; name="restore_file"; filename="malicious.php"
Content-Type: application/x-php
<?php
// malicious code here
?>
--boundary--In this example, the attacker is making a POST request to the ‘admin-ajax.php’ file with the ‘restore_file’ parameter. The ‘restore_file’ parameter is set to a malicious PHP file, which could be executed on the server leading to potential system compromise.
Mitigation Guidance
To mitigate the impact of this vulnerability, it’s recommended to apply the vendor’s patch as soon as it becomes available. In the interim, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can offer some level of temporary protection by blocking or alerting on suspicious activities. Additionally, website administrators could consider limiting access to the ‘start_restore’ function to only trusted administrators, or disabling the plugin until a patch is available.
