The version of tested product installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the cisco-sa-anyconnect-dll-injec-pQnryXLf advisory. Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
