Today, there is a decent choice of IP cameras for the Tuya ecosystem (Smartlife) but the Sonoff-compatible range seems currently limited to the GK-200MP2B.

Here's a quick look at it.

How to get rid of all ads in MIUI 11

3/07/2020 04:34:00 PM 0
Xiaomi MIUI overlay has greatly improved over the recent years and I start to like it.

What I like less is the increased amount of ads that sneaked in every corner of it

Obviously Xiaomi fail their promise to cut down on ads in MIUI 11.

Thankfully there's always a switch hidden in the most remote part of a menu to turn them off.

Cracking open the iPazzPort KP-62 remote

1/22/2020 11:52:00 AM 0

The iPazzPort KP-62 is an RF remote I bought some time ago thinking it could be better than the H1 or even the unmatched TZ-P3.

I never considered publishing a review for it because of its inherent show-killer feature: the useless and continuous beeping when using the keyboard side.

There's a simple DIY solution to it.

Is your IP Camera (still) vulnerable to XSS?

1/21/2020 11:03:00 AM 0
XSS or Cross Site Scripting is a common vulnerability in software allowing attacker to inject code via the user interface.
Often, an input field just intended to collect a server address or user name will also accept entries of a different nature that will be interpreted by the system.

Low-cost IP Cameras, but also more professional ones, have been exposed to XSS for many years, a good reminder that such network devices should not be directly exposed to the Internet!
Hopefully that vulnerability is now well known and many manufacturers eventually "patched" their devices or reduced the attack surface by removing telnet and ftp altogether.

If your IP camera has a HTTP-based user interface, here's a working example of command injection (for learning purpose). This works great on old generation Veskys and Digoo BB-M2 (the pictures below comes from that model), and does not with the Wanscam models I tested.

First check if the admin interface of your camera as an FTP server settings page like this:

Then instead of FTP Server address, copy this command:
put $(killall telnetd)
That first command killed the running telnet daemon.
The second will now launch the Busybox shell without a user/pass prompt. In the username field, copy this: 
$(telnetd -l /bin/sh)

Click the Set up button to save the entries, and click the "Test" button to send them.
The actual FTP server test will report "Test  ...  Failed" which doesn't matter at all because the commands have been executed.

After that, use any telnet emulator, like Putty, and connect to the camera on port 23

As the owner of the camera, this trick allows you to gain full control on your camera.

Digoo DG-K2: I've seen this face before...

11/11/2019 09:21:00 PM 0
The Digoo DG-K2 is another camera compatible with Smart Life.

This one has a particularly nice design, which also reminds me a bit of a certain character from South Park , but maybe it's just me...
