No uri adapters by jyurek · Pull Request #2435 · thoughtbot/paperclip

jyurek · 2017-04-21T15:26:48Z

Remove the URI adapters. Few people use them by default and they can allow insight into the internal networks of the server. If you want to enable them, add (for example) Paperclip.DataUriAdapter.register to your config/initializers/paperclip.rb file.

Additional note: this needs to be documented, but comments welcome as to where and how.

It might be clearer to write this with no space between cd and (".").

Yeah totally -- I like the direction you took this. In the least I'm glad to have an .unregister method, but the explicit .register method is nice, too.

Also quite happy to have some of the adapters not be the default.

LGTM, but we need to get some docs on this in a future commit.

Some small code comments; I don't know enough to offer overarching feedback.

gabebw · 2017-04-21T16:17:34Z

  class DataUriAdapter < StringioAdapter
+    def self.register
+      Paperclip.io_adapters.register self do |target|
+        String === target && target =~ Paperclip::DataUriAdapter::REGEXP


Could this be REGEXP, without the class qualifiers, since it's in this class?

gabebw · 2017-04-21T16:17:53Z

  class HttpUrlProxyAdapter < UriAdapter
+    def self.register
+      Paperclip.io_adapters.register self do |target|
+        String === target && target =~ Paperclip::HttpUrlProxyAdapter::REGEXP


Same here about REGEXP.

This issue has been assigned CVE-2017-0889.

rongutierrez · 2017-11-17T16:45:02Z

Any idea when this fix will be released? By making the CVE public you are making this high risk issue public without an available fix for users.

Remove the URI adapters. Few people use them by default and they can allow insight into the internal networks of the server. If you want to enable them, add (for example) `Paperclip.DataUriAdapter.register` to your `config/initializers/paperclip.rb` file. This is related to CVE-2017-0889. Elsewhere fix CI: it's `s3.us-west-2` now, with a dot.

This breaks API compatibility. Should have been a major bump.

jvanbaarsen · 2018-01-30T13:46:56Z

@juanibiapina What exactly does it break? (Can be helpful for other people to determine if they can upgrade or not)

juanibiapina · 2018-01-30T15:59:11Z

Now you have to manually enable the handlers, which means you need to make a code change for your application to continue working, otherwise you get Paperclip::AdapterRegistry::NoHandlerError. If you must do a code change, that's a major bump.

That means if you correctly configured bundler to automatically upgrade minor versions, your tests will (hopefully) blow up.

Kevinrob · 2018-02-01T20:40:25Z

Like @juanibiapina said, we lost few hours to understand why ours tests failed after upgrading...
A major version would have been nice. At least, a warning in the changelog 😄.

Kevinrob · 2018-02-01T20:54:30Z

+
+* `Paperclip::UriAdapter` - which accepts a `URI` instance.
+* `Paperclip::HttpUrlProxyAdapter` - which accepts a `http` string.
+* `Paperclip::DataUriAdapter` - which accepts a Base64-encoded `data:` string.


What is the risk with DataUriAdapter? How can we use it safely?
