Sun Java RMIConnectionImpl Deserialization Privilege Escalation Exploit

This module exploits a privilege escalation vulnerability in Sun Java. The specific flaw exists within the deserialization of RMIConnectionImpl objects. Due to a lack of privilege checks during deserialization it is possible to supply privileged code in the ClassLoader of a constructor being deserialized. This allows for a remote attacker to call system level Java functions without proper sandboxing. Exploitation of this can lead to remote system compromise under the context of the currently logged in user.
