"The version of Macrium Reflect installed on the remote Windows host is 7.2.x or 7.3.x prior to version 7.3.5281.
It is, therefore, affected by a privilege escalation vulnerability related to the OpenSSL component. An
unprivileged Windows user can exploit this, by creating the appropriate path to a specially-crafted
openssl.cnf in order to execute arbitrary code with SYSTEM privileges.

Note that Nessus has not attempted to exploit these issues but has instead relied only on the application's
self-reported version number.");
