What the vulnerability does
The ContentMX Content Publisher plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.0.6. This is due to missing or incorrect nonce validation on the cmx_activate_connection function. This makes it possible for unauthenticated attackers to bind their own ContentMX connection via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
Explanation of Vulnerability in Simple Terms
ContentMX Content Publisher versions 1.0.6 and earlier are vulnerable to cross-site request forgery (CSRF) attacks. An attacker can craft a malicious webpage that, when visited by a logged-in site administrator, performs unwanted actions on the Content Publisher without the admin's knowledge or consent. The vulnerability requires user interaction—the admin must visit the attacker's page while authenticated.
What an attacker can do
Perform unwanted actions on the Content Publisher by tricking a logged-in admin into visiting a malicious webpage.
Potential impact on your site
Attackers can modify content or settings if they trick your admin into clicking a malicious link while logged in.
Conditions required to exploit
Admin must be logged into Content Publisher and visit attacker-controlled webpage.
