How the Exploit Works

The vulnerability arises from missing authorization checks in the SEO Metrics WordPress plugin’s seo_metrics_handle_connect_button_click() AJAX handler and the seo_metrics_handle_custom_endpoint() function. The AJAX action only verifies a nonce, without checking the caller’s capabilities. This oversight allows a subscriber-level user to retrieve the token and then access the custom endpoint. Once the endpoint is accessed, the user can obtain full administrator cookies, escalating their privileges and potentially leading to system compromise or data leakage.

Conceptual Example Code

Below is a hypothetical example of how an attacker might exploit this vulnerability:

POST /wp-admin/admin-ajax.php?action=seo_metrics_handle_connect_button_click HTTP/1.1
Host: vulnerable-website.com
Content-Type: application/json
{ "nonce": "retrieved_user_nonce" }
// After obtaining the token
GET /wp-admin/admin-ajax.php?action=seo_metrics_handle_custom_endpoint&token=retrieved_token HTTP/1.1
Host: vulnerable-website.com

After these requests, the attacker would receive the administrator-level cookies, gaining full control over the WordPress site.

Mitigation Guidance

To mitigate this vulnerability, users of the SEO Metrics plugin for WordPress should apply the latest vendor patch. If the patch is not available or cannot be applied immediately, using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can provide temporary mitigation. Regularly updating and patching software is a critical part of cybersecurity best practices, as it helps protect systems from known vulnerabilities and exploits.
