## Vulnerable Application
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).
Note: You have the option to use the authentication bypass or not since it requires that the server is rebooted. The password reset will render the authentication useless. Typically, if an administrator cant login, they will bounce the box. Therefore, this module performs a heart beat request until the box is bounced and then attempts to login and to perform the command injection. This module has been tested on version 2.6.1062r1 of the appliance.
Trend Micro are not patching this vulnerability since this product is now ([EOL](https://success.trendmicro.com/solution/1105727-list-of-end-of-life-eol-end-of-support-eos-trend-micro-products)).
![Demo](http://srcincite.io/poc/CVE-2016-7547.gif)
**Vulnerable Application Installation Steps**
List the steps needed to make sure this thing works
- [ ] Download the ISO from ([Trend Micro's](http://download.trendmicro.com/products/tda/TDA_InstallationCD.2.6.1062r1.en_US.iso)) download site.
- [ ] Setup the VM to have 2 NIC's, 100 Gig HD and 4096 RAM.
- [ ] Click through the default install.
- [ ] You are ready to burn.
**Verification Steps**
A successful check of the exploit will look like this:
