affected by a missing authentication flaw in its Ehcache RMI component. An unauthenticated, remote attacker could 
exploit this to bypass authentication and execute arbitrary code on an affected system.

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