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 ALAS-2020-1457 advisory.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
This plugin has been deprecated due to Amazon pulling the previously published advisory.
