[jira] [Created] (SLING-5288) Restrict which classes can be deserialized

Bertrand Delacretaz created SLING-5288:
------------------------------------------

             Summary: Restrict which classes can be deserialized
                 Key: SLING-5288
                 URL: https://issues.apache.org/jira/browse/SLING-5288
             Project: Sling
          Issue Type: Bug
          Components: General
            Reporter: Bertrand Delacretaz


To avoid a recently reported Java deserialization vulnerability [1], we should restrict which classes are accepted when deserializing binaries.

I have created a prototype SafeObjectInputStream at [2], which refuses to operate on classes that are outside a whitelist.

We probably also need a wrapper for ObjectInputStreams provided by the environment, that looks a bit harder to create, for now we can already discuss this prototype to see if we want to pursue the idea.
