Description
The On Page SEO + Social Live Chat plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 2.0.3 due to missing nonce validation in the robots.txt settings handler (Submit and Reset actions) of the settings page. This makes it possible for unauthenticated attackers to overwrite the site's robots.txt file with arbitrary content or reset it to defaults via a forged request, granted they can trick a site administrator into performing an action such as clicking on a link.
