Detailed vulnerability description

The vulnerability allows a remote attacker to perform cross-site request forgery attacks.

The vulnerability exists due to the lack of CSRF and authorisation checks in the settings page, as well as "ajax_enable_ssl()", "ajax_scan()" AJAX methods. A remote attacker can trick the victim to visit a specially crafted web page and perform settings change on the affected system.

This vulnerability also allows a call of the AJAX methods by a low privileged user and arbitrary site options update due to the way the update_option() and update_site_option() are used in the admin() and admin_network() functions.

Remediation

Install updates from vendor's website.
