Impact: System compromise and potential data leakage due to unauthorized deletion and manipulation of website content.

Affected Products

Product | Affected Versions

EazyDocs WordPress plugin | Versions prior to 2.3.6

How the Exploit Works

The vulnerability stems from a lack of appropriate authorization and Cross-Site Request Forgery (CSRF) checks within the EazyDocs plugin. An attacker can exploit this vulnerability by sending a crafted HTTP request to the server. The server, failing to check the request’s authenticity and authorization, will comply, allowing the attacker to delete arbitrary posts and add or delete documents/sections.

Conceptual Example Code

POST /wp-admin/admin-ajax.php?action=eazydocs_delete_post HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
post_id=10

In this conceptual example, an attacker sends an HTTP POST request to delete the post with ID 10. This example assumes the vulnerabilities in the EazyDocs plugin that have not been patched, allowing the request to proceed without any authentication or CSRF checks.

Mitigation

Users are advised to update the EazyDocs WordPress plugin to version 2.3.6 or later, where the vulnerability has been fixed. As a temporary workaround, users could use a web application firewall (WAF) or an intrusion detection system (IDS) to block malicious requests. However, these are not long-term solutions and the plugin should be updated as soon as possible.
