wpCentral <= 1.5.7 is vulnerable to Cross Site Request Forgery (CSRF) vulnerability

The wpCentral plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.5.7. This is due to missing or incorrect nonce validation on the wpcentral_page_handler() function. This makes it possible for unauthenticated attackers to update allowed IPs and reset the connection key via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
