"The version of Rockwell FactoryTalk Services Platform installed on the remote Windows host is prior to 6.20. It is, 
therefore, affected by a vulnerability.

  - FactoryTalk Services Platform contains a vulnerability that may allow a
    remote, authenticated attacker to bypass FactoryTalk Security policies based
    on the computer name. If successfully exploited, this may allow an attacker
    to have the same privileges as if they were logged on to the client machine.

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