WP Tweet Walls < 1.0.4 - Cross-Site Request Forgery

Description

The WP Tweet Walls plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.0.3. This is due to missing or incorrect nonce validation on several functions like wptw_ajax_delete_wall, wptw_ajax_update_wall, wptw_ajax_get_wall, and wptw_ajax_is_limit_reached. This makes it possible for unauthenticated attackers to modify wall settings via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
