10.11.x prior to 10.11.00.01. It is, therefore, affected by a remote
code execution vulnerability in the RMI registry due to unsafe
deserialize calls of unauthenticated Java objects to the Apache
Commons Collections (ACC) library. An unauthenticated, remote attacker
can exploit this, by sending a specially crafted request, to execute
arbitrary code on the target host.");
