The version of tested product installed on the remote host is 18.2 prior to 18.2R1-S2, 18.2R2 on an EX4300-MP Series device with any lo0 filters applied. It is, therefore, affected by a vulnerability. The transit network traffic may reach the control plane via loopback interface (lo0). The device may fail to forward such traffic as referenced in the JSA10933 advisory.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
