Description
The IMPress for IDX Broker plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'impress_property_showcase' and 'impress_property_carousel' shortcodes' 'property_type' and 'saved_link_id' attributes and the 'wp_listings_meta' shortcode's 'key' attribute in all versions up to, and including, 3.3.1, due to insufficient input sanitization and output escaping. The showcase and carousel attributes are placed unescaped inside an HTML comment, which a value containing '-->' can close, and the 'key' attribute is printed in an unquoted class attribute. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
