"According to its self-reported version number, the version of Dell EMC Data Protection Central hosted on the remote web
server is 1.0, 1.0.1, 18.1, 18.2 or 19.1. It is, therefore, affected by an improper certificate chain of trust
vulnerability. An unauthenticated, remote attacker can exploit this, by obtaining a CA signed certificate from Data 
Protection Central to impersonate a valid system to compromise the integrity of data.

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