Tenvis IP Camera JPT3815W


Recommended Posts

Im currently working on a project of trying to pen-test this cheap IP camera I bought online I've port scanned it a few times and the only thing open is 

7777/tcp  open  cbt
49152/tcp open  unknown

I've done some research and a few wireshark scans and have found out that the 7777 port is for transmitting the image of the camera and port 49152 is for UPnP and port forwarding. Is anyone familiar with any vulnerabilities that I could exploit using this information? This is my first hardware pen-test btw. I'm thinking about opening it up and trying to see if there is any serial connections.

Any advice is appreciated :)

Update: I have looked further into the firmware file and used binwalker to extract some of the files since they aren't encrypted.

One is called chpasswd.sh and the contents is:


# $Id: chpasswd.sh,v 1.1 2008-05-19 13:08:34 winfred Exp $
# usage: chpasswd.sh <user name> [<password>]

    echo "Usage:"
    echo "  $0 <user name> [<password>]"
    exit 1

if [ "$1" == "" ]; then
    echo "$0: insufficient arguments"
    usage $0

echo "$1:$2" > /tmp/tmpchpw
chpasswd < /tmp/tmpchpw
rm -f /tmp/tmpchpw



Also after port scanning using -sS I found that there are more ports than I originally thought, most are filtered though.

Starting Nmap 7.40 ( https://nmap.org ) at 2018-03-16 11:37 EDT

I feel like I am on the right track but some help would be appreciated. Also I can post the folder of all the files I extracted from the .bin firmware file If you guys want
