Form Validation Errors Node

Form Validation is used by form dialogs to warn users about errors in their submissions to a website.

Forms are generally used to create a new account, newsletter sign-up, password reminder, shipping address details, and other similar pages. They require the web application's visitors to enter information such as a phone number, email address, or credit card number.

Many of these web forms typically have some basic checks because some of the fields might be mandatory. The form validation ensures that users submitted data that matches the requirement set in the form controls.

To identify the attack surface, Netsparker tries to fill out and submit these forms to access the pages that are typically only accessible once the form is submitted. You can define values or enter new values that Netsparker enters into these forms. For further information, see Configuring Predefined Web Form Values.

Once the scan is completed, all form validation errors are listed under the Form Validation Errors node in the Knowledge Base. You can access the same information in the Knowledge Base Report and Knowledge Base Tab.

For further information, see Knowledge Base Nodes.

Netsparker forms Knowledge Base nodes on its findings. If the Form Validations Errors node is not listed, it means that Netsparker did not find any.

For further information, see Knowledge Base Nodes.
