Re: [cross-project-issues-dev] Question on commons-collectionsdependencies


Riena does not use Java Serialization and Deserialization for the remote service calls but it uses Hessian Serialization. While the protocol is totally different it also calls the readObject Method upon completion of the deserialization of the object which I believe could lead to a problem.

I have opened a bug against Riena to track the effort

The solution for us is to use org.apache.commons.collections 3.2.2. Riena itself does not use commons.collections but org.apache.commons.beanutils which in turn uses commons.collections.

What are about all the other projects that use remote services and I believe there are a few ? I wonder if they are also effected ?


P.s. Apache has released 3.2.2. Which fixes the problem (disables the problemactic class by default)

First, org.apache.commons.collections is in Orbit, so there may be other teams affected by this possible exploit. We're working to get the "fixed" version - 3.2.2 - into Orbit. Second, WTP is in the process of determining how to handle this issue- you can follow if you want to see how we decide to proceed.
Part of the issue is that any adopter that extends Dali has the potential to deserialize persisted objects- we can't control what adopters do... but we can reduce/eliminate the possibility that a security hole can be exploited.

Hi All:

You may have seen the recent news about deserializing random streams via
commons-collections [1]  and how this can lead to remote exploits.  
While it seems pretty unlikely that eclipse is vulnerable to this, it's
worth noting that commons-collections is a requirement of
org.eclipse.jpt.jpa, and possibly other bundles in various distributions.

I may be misunderstanding the issue, but as I understand it, simply
having the jar on the classpath isn't enough to exploit. Instead, you
must actually be either 1) using the library to deserialize some
persisted (untrusted) java object, or 2) be exposing ports and accepting
arbitrary serialized data and then deserializing it.

So the question is, do any eclipse distributions  (classic,  jee, etc)
have any reason to open ports and accept remote connections and blindly
deserialize the data?
