I think an attack vector that is often under-analyze is the web service.  There’s no user interface, so what’s the real danger? Cross-Site Scripting (which accounts for about 53% of all application vulnerabilities) is completely useless since there is no HTML response.  And how would one even use this tool without a user interface?

Direct Access and Completely Unprotected Functionality In many cases of broken access controls, sensitive functionality and resources can be accessed by anyone who knows the relevant URL.  Some applications may enforce access controls by simply not displaying the usable link or button to access the resource. To effectively scan for these weaknesses, first open an […]
