12. # Description
13. In vulnerable versions of nginx,null bytes are allowed inURIsbydefault(their presence is indicated via a variable named zero_in_uri definedin ngx_http_request.h).Individual modules have the ability to opt-out of handling URIswithnull bytes.However,not all of them do;in particular, the FastCGImodule does not.
