Description
The Mapster WP Maps plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'id' parameter of the Mapmaker admin page in versions 2.0.3 to 2.0.4 due to insufficient input sanitization and output escaping. The raw value is echoed into a hidden input's value attribute. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a site administrator into performing an action such as clicking on a link.
