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


- 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...
- Auth is now bypassed, please see CVE-2016-7552
