Description

The WP-Ultimate-Map plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.1. This is due to missing nonce validation on the process_init() function hooked to admin_init, which saves plugin settings (zoom-level, focus-lat, focus-lng, sel_places, sel_routes) via update_option() based solely on the presence of a save-setting POST parameter. Additionally, the saved values — particularly zoom-level — are stored without sanitization and later echoed into an HTML attribute (and inline JavaScript) on the settings page without escaping. This makes it possible for unauthenticated attackers to change plugin settings and inject arbitrary web scripts via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
