"The version of Adobe Experience Manager installed on the remote host is 6.4 or 6.5 without hotfixes
cq-6.4.0-hotfix-31868 or cq-6.5.0-hotfix-31870. It is, therefore, affected by an uncontrolled resource consumption
vulnerability which, if successfully exploited, leads to a denial-of-service (DoS) condition.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number. To retrieve patch level information this plugin requires the HTTP credentials of the web console. For accurate
results, you may need to enable the Adobe Experience Manager ports (by default, 4502 and/or 4503) in your Nessus
scan.");
