CSRF detection behavior

Hi,

 

I understand how QualysGuard WAS tests for the existence of CSRF vulnerabilities in web applications. With one customer's website I'm seeing a lot of false positives and I suspect this is caused due to server misconfiguration. The problem is that currently the server responds with HTTP 200 and a message in the page stating the anti-CSRF token isn't correct. Would it be better to respond with HTTP 400 instead, or maybe another code, to prevent QualysGuard from reporting a CSRF vulnerability?

 

Kind regards,

Geert Smelt
