Description

All Apache Synapse releases previous to 3.0.1 installed on the remote host are affected by a Remote Code Execution vulnerability. This can be performed by injecting specially crafted serialized objects. And the presence of Apache Commons Collections 3.2.1 (commons-collections-3.2.1.jar) or previous versions in Synapse distribution makes this exploitable. To mitigate the issue, we need to limit RMI access to trusted users only. Further upgrading to 3.0.1 version will eliminate the risk of having said Commons Collection version. In Synapse 3.0.1, Commons Collection has been updated to 3.2.2 version.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
