'Name' => 'Trend Micro Threat Discovery Appliance admin_sys_time.cgi Remote Command Execution',
'Description' => %q{
This module exploits two vulnerabilities the Trend Micro Threat Discovery Appliance.
The first is an authentication bypass vulnerability via a file delete in logoff.cgi
which resets the admin password back to 'admin' upon a reboot (CVE-2016-7552).
The second is a cmdi flaw using the timezone parameter in the admin_sys_time.cgi
interface (CVE-2016-7547). You have the option to use the authentication bypass or
not since it requires that the server is rebooted. This module has been tested on
version 2.6.1062r1 of the appliance.
