Question

An ethical hacker is testing a web application of a financial firm. During the test, a 'Contact Us' form's input field is found to lack proper user input validation, indicating a potential Cross-Site Scripting (XSS) vulnerability. However, the application has a stringent Content Security Policy (CSP) disallowing inline scripts and scripts from external domains but permitting scripts from its own domain. What would be the hacker's next step to confirm the XSS vulnerability?

Options

  • AUtilize a script hosted on the application's domain to test the form
  • BTry to disable the CSP to bypass script restrictions
  • CInject a benign script inline to the form to see if it executes
  • DLoad a script from an external domain to test the vulnerability
