The version of SolarWinds Serv-U installed on the remote host is prior to 15.4.2. It is, therefore, affected by a directory traversal remote code vulnerability as referenced in the serv-u_15_4_2 advisory. This vulnerability requires a highly privileged account to be exploited.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
