Why do you use an insecure config? It's even referenced in the wiki: 
http://wiki.nginx.org/Pitfalls#Passing_Uncontrolled_Requests_to_PHP

I'm aware that is quite common to "recommend" this as de rigueur for
PHP but I fail to see why, It seems that is just easier to have a
catch all php than enumerate all scripts that are allowed.

Maxim suggestion doesn't work for you because you have this regex
based location. I suggest you formulate your problem more clearly so
that the list can help you.

Start by trying an exact location for index.php

location = /index.php {
    ...
}

location = /products {
     ...
}
  
You have to "enable" PHP FCGI handling in each location.
