How the Exploit Works

The vulnerability resides in the ‘TH_LatestPosts4` widget of the Kallyas theme for WordPress. The flaw allows authenticated attackers, with Contributor-level access or higher, to include and execute arbitrary .php files on the server. This enables the execution of any PHP code present within the included files, which could bypass access controls, obtain sensitive data, or achieve code execution especially when .php file types can be uploaded and included.

Conceptual Example Code

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

POST /wp-admin/admin-ajax.php?action=th_latest_posts4 HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
file=../../../wp-config.php

In the example above, an attacker requests the WordPress configuration file (`wp-config.php`), which contains sensitive information such as database credentials. This request uses directory traversal (`../../../`) to navigate to the location of the `wp-config.php` file.
