Developer And Remediation Guidance

How teams prevent and detect this weakness

Causes

  • This code queries a server and displays its status when a request comes from an authorized IP address. This code redirects unauthorized users, but continues to execute code after calling http_redirect(). This means even unauthorized users may be able to access the contents of the page or perform a DoS attack on the server being queried. Also, note that this code is vulnerable to an IP address spoofing attack (CWE-212).

Remediation

  • Use safe APIs
  • Centralize the control
  • Add regression tests
  • Review logs and telemetry for attempted abuse

Detection

  • Black Box: This issue might not be detected if testing is performed using a web browser, because the browser might obey the redirect and move the user to a different page before the application has produced outputs that indicate something is amiss.
