Executive Summary

The CM Ad Changer plugin for WordPress, up to version 2.0.7, is vulnerable to a Cross-Site Request Forgery (CSRF) attack. This vulnerability arises because the plugin's cmac_campaigns_action function lacks proper nonce validation. As a result, an attacker can trick a site administrator into performing unintended actions, such as clicking a malicious link, which allows the attacker to permanently delete advertising campaigns along with their associated banners and uploaded files without authentication.

Impact Analysis

This vulnerability can lead to the permanent deletion of advertising campaigns, including banner records and uploaded files, on a WordPress site using the CM Ad Changer plugin. An attacker does not need to be authenticated but must trick an administrator into performing an action, such as clicking a link. This can disrupt advertising operations and cause data loss related to campaigns.
