|

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.
