Ultimate Review <= 2.4.3 - Unauthenticated Persistent Page Denial of Service
The Ultimate Review plugin for WordPress is vulnerable to Denial of Service in all versions up to, and including, 2.4.3. This is due to missing isset() guard on the review_location key of the display settings option, which is an empty string when never saved, causing a fatal PHP error when accessed as an array in the shortcode and content-filter handlers. This makes it possible for unauthenticated attackers to cause a persistent denial of service on any reviewed page by submitting a review when the plugin's display settings have never been saved, triggering a fatal PHP error on every subsequent visit to that page. The WP Ultimate Review display settings must have never been saved (fresh install with no settings configuration), leaving the xs_review_display option unset.
