WP Emoticon Rating <= 1.0.1 - Cross-Site Request Forgery to Reflected Cross-Site Scripting via 'emo_settings' Parameter
Description
The WP Emoticon Rating plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.0.1. This is due to missing or incorrect nonce validation on a 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.

Summary
The WP Emoticon Rating plugin for WordPress is vulnerable to Cross-Site Request Forgery (CSRF) in versions up to 1.0.1. Due to missing nonce validation on settings updates, an attacker can trick an administrator into submitting a request that injects malicious JavaScript via the 'emo_settings' parameter, leading to Reflected Cross-Site Scripting (XSS).
Exploit Outline
1. Host a malicious HTML page containing a hidden form that targets the WordPress administrative dashboard (e.g., /wp-admin/admin.php?page=wp-emoticon-rating). 2. Include an input field named 'emo_settings' in the form with a reflected XSS payload, such as: "><script>alert(document.domain)</script>. 3. Add a script to the malicious page that automatically submits the form (document.forms[0].submit()) upon page load. 4. Induce a logged-in site administrator to visit the malicious URL. 5. Since the plugin does not verify a cryptographic nonce, the settings update will be processed, and the injected script will execute in the context of the administrator's session.
