What the vulnerability does
The Seo Monster plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 3.3.3. This is due to missing or incorrect nonce validation on the check_integration() function. This makes it possible for unauthenticated attackers to update settings and inject malicious web scripts 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
Seo Monster versions 3.3.3 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 site without the admin's knowledge or consent. The attacker has no special privileges and the impact is limited to data modification.
What an attacker can do
Perform unwanted actions on the site by tricking a logged-in admin into visiting a malicious webpage.
Potential impact on your site
An attacker can modify site data or settings by exploiting an admin's active session without their awareness.
Conditions required to exploit
A site administrator must visit a webpage controlled by the attacker while logged into the site.
