Detailsinfo

A vulnerability was found in Gravity Forms Plugin up to 2.9.30 on WordPress. It has been rated as problematic. Affected by this issue is the function get_value_entry_detail of the component Dashboard. The manipulation of the argument input_.4 with an unknown input leads to a cross site scripting vulnerability. Using CWE to declare the problem leads to CWE-79. The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. Impacted is integrity. CVE summarizes:

The Gravity Forms plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Credit Card field's 'Card Type' sub-field (`input_.4`) in all versions up to, and including, 2.9.30. This is due to the `get_value_entry_detail()` method in the `GF_Field_CreditCard` class outputting the card type value without escaping, combined with `get_value_save_entry()` accepting and storing unsanitized user input for the `input_.4` parameter. The Card Type field is not rendered on the frontend form (it is normally derived from the card number), but the backend submission parser blindly accepts it if included in the POST request. This makes it possible for unauthenticated attackers to inject arbitrary web scripts that execute when an administrator views the form entry in the WordPress dashboard.
