8.0.0.15, 8.5.0.x prior to 8.5.5.14 or 9.0.x prior to 9.0.0.8. It is, therefore, affected by an information disclosure
vulnerability in the Apache Commons HttpClient subcomponent due to the failure to  verify that the server hostname
matches a domain name in the subject's Common Name (CN) field of the X.509 certificate. An unauthenticated, remote
attacker can exploit this to conduct spoofing attacks, by persuading a victim to visit a web site containing a
specially-crafted certificate.

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