Technical description
The CM Ad Changer – A simple tool to control and optimize your site's banners plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 2.0.7. This is due to missing or incorrect nonce validation on the cmac_campaigns_action function. This makes it possible for unauthenticated attackers to permanently delete arbitrary advertising campaigns, including their associated banner records and uploaded files via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
