[Bug 52774] RewriteRules within outgoing proxy no longer work

https://issues.apache.org/bugzilla/show_bug.cgi?id=52774

--- Comment #14 from Joe Orton <jorton [at] redhat> ---
See list discussion here:

http://comments.gmane.org/gmane.comp.apache.devel/48357

I have added a new RewriteOption, "AllowAnyURI", in r1356115 which IMO resolves
this issue. Other opinions are available! :)

Doesn't mean "AllowAnyURI" option actually "allow CVE-2011-3368/CVE-2011-4317"?

And is following statement correct?

"Declining, request-URI 'http://blahblah' is not a URL-path"

I believe http://blahblah is valid URL path.

And what is problem with the patch I proposed? Is it vulnerable for
CVE-2011-3368/CVE-2011-4317? I hope not.

I think I just don't understand it.. :-)

If you write a rule that captures/substitutes unsafely, and opts into non-path
arguments, yes.

The path is 1 component of a URL, we use the term "URL-path" for that
component.

IMO it is too narrow and does not force the user to opt in to the input
sometimes not being a URL path (as it had been documented)
