Description David Jorm 2013-08-08 23:27:05 UTC 
Restlet applications which use ObjectRepresentation to map HTTP request data directly to an object will deserialize arbitrary user-provided XML using XMLDecoder. XMLDecoder will deserialize an attacker-provided definition of a class and execute its methods. A remote attacker could use this flaw to perform remote code execution in the context of the server running the Restlet application.
