The error message 'Unable to complete request: Unrecognized field <ext2_price>' indicates that the application encountered a field it was not expecting. This often happens when unexpected or additional fields are injected into a form submission, which can be a sign of a form tampering attack. Implementing Form Field Consistency ensures that the submitted data matches the application's expected form structure and fields, preventing unexpected fields from being processed. This protects against this type of error and potential security vulnerabilities.
D. Form Field Consistency The error message "Unable to complete request: Unrecognized field" suggests that the web application received data that it wasn't expecting, which could be an indication of an attempted injection attack. Implementing Form Field Consistency checks can help ensure that the submitted form data matches what the application expects, both in the number of fields and the type of data each field should contain. This protection can prevent various types of attacks, including but not limited to SQL Injection, by ensuring that only expected form fields are submitted and that they contain data consistent with the application's expectations.
