LG WEBOS 4.0 and below. Letsencrypt root certificated expired.


Recommended Posts

Found multiplex application that use letsencrypt stop working in 30 September 2021 on LG WebOS 3.5. This appear to be wide spread multiplex version of WEBOS.

As PLEX blaming to be LG fault. LG please provide solution to only 2 year old TV

LG

Our current app is available on 4K/UHD LG television models running the following system software:

  • webOS 3.0
  • webOS 3.5
  • webOS 4.0
  • webOS 5.0

No 720p or 1080p (“full HD”) sets are supported for our current app at this time.

Note: Due to root certificate limitations with the device OS itself, only webOS 5.0+ devices support secure connections with a personal Plex Media Server. To allow connections to a personal server, devices running earlier webOS versions must be set to Allow Insecure Connections in the TV app settings and the Plex Media Server must be set to Preferred for the Secure Connections preference.

Same here on my 2 year old 65SK8000PLB with firmware 05.40.09

I cannot load any websites with Letsencrypt encrypted certificates.

Examples:

This is a good example for unsufficient product lifecycle management.

I've got 

I've got this problem too with my OLED55E6V (AKA: the E6). I bought it in 2017. I find it baffling that a modern smart TV like has this problem. Built in obsolescence? LG should sort this out. I spent thousands of £ on this.

I have a Plex Media Server. I've tried the server and app settings to allow insecure connections but that isn't working.

Isn't this just a case of LG updating certificates?

The TV received a firmware update recently. Surely LG can resolve this?

It should be very easy for LG to exchange the root certificates with an update. However, the question is whether this will happen....

Connections to older Plex servers still seem to work.
Also to those in the same network that are up to date but do not have their own certificates.

Whether this is really the problem is questionable.
However, SSL should be the most important thing these days and that must be running!

It definitely is the problem.  Here's what works to recreate it on my 55B6, on firmware 5.60.25.

Manually set your TV clock to Sept 30, 9AM EDT (convert to your time zone if needed).

Goto any Wikipedia page using the browser. Works.

Manually set your TV clock to Sept 30, 11AM EDT (convert to your time zone if needed).

Goto any Wikipedia page using the browser. Does NOT work, you get a security error that cannot be bypassed.

Now manually set your TV clock back to Sept 30, 9AM EDT again (convert to your time zone if needed).

Goto any Wikipedia page using the browser. Works again.

A root cert (DST Root CA X2) expired around 10AM EDT on September 30th. Servers using Let's Encrypt certs (which includes Wikipedia) should be testable using either that root or the newer ISRG Root X1 - which, by the way, has been around since June 2015. If you have not updated the trusted root list attached to the browser since 2015, then you will see this failure, because after 10AM Sept 30th, only the ISRG Root X1 is still valid.

LG has had FIVE YEARS to fix this problem before it happened.

I have a C9 and rooted the TV once the RootMy.TV exploit came out. Thanks to this, Im able the overwrite all the expired certificates and everything works great again
Where do I get the updated certificated, and where do I put them in the fillesystem?

If your TV is rooted, you can use a bash script I wrote to remove the expired LetsEncrypt cert and add two new certs to the TV's truststore.  Open a shell on your TV and run the following four commands:

cd /tmp

wget  

link hidden, please login to view

chmod +x update-ca-certs.sh

./update-ca-certs.sh

After updating the certs, the TV will reboot, and you should be good to go.

Can you please make some tutorial how to do it step by step for fresh people ?

Hi TAM,

I found a few issues with your script,

1. wget doesn't work on my TV I get - wget: not an http or ftp url:

2. Tried to overcome that by just downloading the script and SCP it to the TV that worked fine BUT you have wget again in the update-ca-certs.sh so I had to download and SCP the certs to the correct folders - NOW the final issue I see is and cannot understand is how is  /media/cryptofs/apps/usr/palm/services/com.palmdts.devmode.service/start-devmode.sh going to run and apply the setting? what will trigger this script?

Thanks, From what I can find you are the only one really working on this issue - Really appreciate it!

UPDATE:

To over come the wget issue I just used 'curl -k  --output update-ca-certs.sh'

I also update the 'update-ca-certs.sh' and replaced wget with curl --output' script (attached)   update-ca-certs.txt

still not seeing the certificates updated

Hi Fem,

Thanks for pointing out the issue with wget. I may have installed wget myself some time ago and forgotten, so maybe it is a different version to the one you have. I have updated the script and instructions to use curl instead.

The script at /media/cryptofs/apps/usr/palm/services/com.palmdts.devmode.service/start-devmode.sh was created by the rooting process I used. So this file existed before I made any changes myself. It gets executed automatically each time the TV is switched on, so I just appended a few commands to the end of that script (to overlay the new certs and cert config onto the underlying readonly filesystem, and to force the system to recognise these new certs each time). If you used a different mechanism to get root, then maybe you have some script that executes on startup that you could append these commands to instead.

Nobody knows if LG is going to fix it, but honestly, the community already has.  I'll summarize what I did which was based on everyone's helpful instructions above, meant for someone who knows little to nothing about telnet, ssh, etc.  (If you are familiar with those applications, this will be a breeze.  If not, just follow the instructions and search the web if you'd like to learn more about the commands used.)

Note that most of these instructions are taken from 

link hidden, please login to view
 and may be slightly different depending on your TV.

On your TV...

  1. Turn on your TV
  2. Open the web browser app
  3. Browse to rootmy.tv
  4. Slide the little "Slide to root" bar to the right if you have the kind of remote that lets you use an on-screen pointer or just press the number 5 on your remote
  5. Accept the security prompt
  6. The exploit will proceed automatically and the TV will reboot itself; choose to reboot a second time to finalize the installation of the Homebrew Channel (the TV may turn off instead of rebooting - if this happens, just turn the TV back on again)
  7. Your TV should now have Homebrew Channel app installed, and an unauthenticated(!) root telnet service exposed
  8. Go to the TV's network settings and write down its IP address

Note that your TV must be turned on in order to connect to it remotely; when it's off, it's all the way off (although there may be a non-power-saving setting you can enable to keep the TV's operating system running when it's off so that it will turn on faster, in which case you might be able to connect to it even when it's off).

On your computer...

  1. Enable telnet (sorry Mac users, you'll need to figure this out on your own)
    • Click on the Windows Start Menu
    • Type "Windows Features" and click on "Turn Windows features on and off"
    • Scroll down to Telnet client and check the box
    • Click OK
  2. Open a command prompt (Win+R then type "cmd")
  3. Generate an encryption key pair that will be used to connect securely to the TV
    • Type "mkdir .ssh" to create the secure shell directory if it's not there already
    • Type "ssh-keygen -t rsa -f .\.ssh\lgtv_rsa" (the file name can be anything you want, but that's what I used)
    • Type "notepad .ssh\config"
    • Paste the following contents into the newly created file:
      Host 1.2.3.4
          User root
          IdentityFile C:\Users\yourusername\.ssh\lgtv_rsa

      Replace "1.2.3.4" with your TV's IP address you wrote down in step 8 above
      Replace "yourusername" with the directory name where your user data is stored

    • Save the file and quit Notepad

    • Type "type .ssh\lgtv_rsa.pub" (it will spit out some ugly text - this is your public encryption key)

    • Select all the text and copy it to your clipboard - you'll need this shortly

  4. Type "telnet 1.2.3.4", where 1.2.3.4 is your TV's IP address you wrote down in step 8 above, to connect to your TV
    (No username or password is required to connect as the "root" user - we'll fix this security hole in a moment)
  5. Type "vi /home/root/.ssh/authorized_keys"
  6. Once the new empty file opens, type the letter "i" to enter insert mode
  7. Press Ctrl-V to paste in the clipboard contents, which is the public key generated in step 3
  8. Press the "Esc" (Escape) key to exit insert mode
  9. Type ":wq!" and press Enter to write the file and then quit the editor immediately
  10. Type "exit" to exit the telnet application
  11. Type "exit" again to exit the command prompt

Back on your TV...

  1. Open the Homebrew Channel
  2. Go to Settings (the Gear icon)
  3. Disable Telnet
  4. Enable SSH Server
  5. Enable Block system updates
  6. Reboot the TV

Back on your computer, apply Tam's SSL fix...

  1. Disable telnet (follow the instructions in "On your computer" above but uncheck the box next to Telnet client instead of checking it this time)
  2. Open a command prompt (Win+R then type "cmd")
  3. Type "ssh 1.2.3.4" (not telnet this time!), where 1.2.3.4 is your TV's IP address, to connect to your TV
    (again, no username or password is required, but it's still secure since the encryption key you generated above is used)
  4. Follow Tam's instructions above, repeated here (I suggest copy/pasting the "wget" line from the browser into your command prompt window):
    (Now, if you're like me, the "wget" command will fail because the version running on the TV doesn't have the capability of connecting to secure HTTPS web sites.  Skip to the Alternate Instructions if you have the same issue with the "wget" command.)
    cd /tmp
    wget  https://raw.githubusercontent.com/tf318/lg/main/update-ca-certs.sh
    chmod +x update-ca-certs.sh
    ./update-ca-certs.sh

Alternate instructions

If the "wget" command failed, follow these steps instead:

  1. Open Tam's script file in this browser in another tab: 
  2. Copy the text and then close that tab
  3. Return to the command prompt...
  4. Type "vi /tmp/update-ca-certs.sh"
  5. Once the new empty file opens, type the letter "i" to enter insert mode
  6. Press Ctrl-V to paste in the clipboard contents, which is the Tam's script
  7. Press the "Esc" (Escape) key to exit insert mode
  8. Type ":wq!" and press Enter to write the file and then quit the editor immediately
  9. Type the following two commands:
    chmod +x update-ca-certs.sh
    ./update-ca-certs.sh

 

Whether using Tam's original instructions or my Alternate version, the TV will reboot (twice, maybe) and Plex should now open and be happy.  At least mine was.  Thanks again, RootMy.TV team and Tam, for all your research and hard work!

Just wanted to say thanks for this comprehensive guide. I did have some issues using rootmytv - my LG firmware has patched that so it didn't work so I had to downgrade it. That was a bit of a faff but dropping back to firmware version 05.30.10 allowed me to complete the process.

Firmware can be obtained here for my TV.

....

appreciate the step-by-step guide! i was able to get this working via chromebook with the included ssh capability in developer mode. however, i do have a question.  do you know if removing the root via factory reset will also remove the updated certs?

I too had the same issue. Kept getting no such file or directory when connected via telnet. I tried the mkdir and bypassed that. Then I hit another roadblock when trying to connect via ssh, asks me for a password. No idea what that is so I gave up. Any help is appreciated.

I tried the SSH as well, same thing, asked me for a password.  I tried the password  "<BLANK>", "root", "password", "alpine" which is from the RootMyTV documentation, but still no luck.

Terribly sorry for the months of delay in replying to you, but this sounds like a permissions issue or a missing directory (as Stirfriedrice determined).

In case anyone else has that issue, before you execute the On your computer step 5. "vi /home/root/.ssh/authorized_keys" command to edit the file, execute this command first which will create the .ssh directory (and its parents, if necessary):

mkdir -p /home/root/.ssh

As for the "ssh" command prompting for a password, that can only be because either your local computer is not sending the encryption key as its form of authentication or the TV's ssh server is not accepting it (or cannot access it).  Check to ensure that the encryption key files are in the right place both on your local computer and on the TV.  You can also run your ssh client on your computer in a "verbose" mode with the following command (replace 1.2.3.4 with your TV's IP address):

ssh -v 1.2.3.4

This will tell you a lot more about what's going on when ssh tries to connect.  If you're up for even more verbosity, you can use "-vv" or get maximum verbosity with: "-vvv" (which I don't recommend because it will spit out quite a mess!)

Also, make sure your TV's IP address hasn't changed (mine did since I wrote my original instructions).  If it did, then ssh will not even try to provide it with the encryption key.  Check and update the .ssh\config file on your computer to use the TV's updated IP address and then try again.

The last thing you can try is to ensure that the TV's encryption key and directory has the correct permissions (you'll have to enable and use telnet for this):

chmod 700 /home/root/.ssh
chmod 600 /home/root/.ssh/authorized_keys

And then try to connect via ssh again.

Absolute worst-case scenario - just turn telnet back on and use that instead of ssh, then turn telnet back off again!

It's a dirty little secret: You can use telnet to do everything you need to for this exercise, but all Linux nerds (I'm one by default although I prefer Windows all day) will beg you to use ssh instead as telnet is completely insecure and extremely hackable.

appreciate the step-by-step guide! i was able to get this working via chromebook with the included ssh capability in developer mode. however, i do have a question.  do you know if removing the root via factory reset will also remove the updated certs?

No idea, but I suspect that the answer is "yes."  Give it a shot and let us know! ;)

So, why have I returned?  Well, honestly because my Plex client app broke again, which is odd since I have it locked down as expected so it should still be working.  I was hoping that someone else had this issue and came back here to talk about how they fixed it already!  Looks like I have some work to do myself (if I cannot find it after more searching on the web).  

But...

I just had a pop up letting me know about firmware 05.65.03 for my OLED55B6.

Someone has to be the guinea pig to see if this updates the cert issue. Might as well be me.

Did it work?  Or break things for you?  I suspect it will break things since...

Just wanted to say thanks for this comprehensive guide. I did have some issues using rootmytv - my LG firmware has patched that so it didn't work so I had to downgrade it. That was a bit of a faff but dropping back to firmware version 05.30.10 allowed me to complete the process.

Firmware can be obtained here for my TV.

      I used to be able to surf to OPB.org using WebOs on my LG Smart TV and watch the Livestream with no problem. But about a year ago something changed and the Livestream became covered up by the programming grid (with a little bit showing above the grid) and nothing I can do removes it. Is there a way to watch PBS on my LG Smart TV?

      Please take steps to include Airtel Xtream Play app in WebOS Content Store!
      In India everyone is using Airtel network and Xtream Play as a bundle recharge offer with it!
      LG TV is very good and technically advanced! For this mere reason of not having Airtel Xtream Play App, We Customers, need to switch over to other brands!
      So, it is mandatory and timely, for LG to make Xtream Play available in WebOS TV, otherwise you have to loose your trusted Customers like us!
         Please think twice and Consider!!!

      Hi, my LG webOS TV TN520S is running  software version 05.45.45 and since then the channel 4 and channel 5 apps are broken. You can start to watch a program but as soon as the first set of adverts start, the app just loops and you cant progress past the adverts. I a wondering if this is because the TV is running the latest version of its software (I've searched for newer versions but none are shown). Has anyone else had this problem and is it possible to install a previous version of the TV's software to see if this resolves the problem.

      SEOUL, Oct. 1, 2024 — LG Electronics (LG) announced the winners of its webOS TV platform hackathon, which took place at the LG webOS Summit last week. The event was geared toward AI-based solutions and gaming services, and sought ideas to enhance the gaming category on the Smart TV.
      Developers from around the world applied for the opportunity to present their ideas for apps or services to be used on webOS-based LG Smart TVs in millions of homes, with the goal of diversifying and improving the gaming experience on the LG TVs powered by webOS.
      Over three hundred entries were submitted from more than 50 countries. Finalists were invited to present their ideas onstage to a panel of LG executives and over 300 market-leading companies. The top three winners received a meaningful opportunity to engage with the LG team to develop their ideas and resources for business implementation on webOS. They will continue to work with the LG team to prepare the family-friendly gaming solutions for LG TVs by June 2025. Cash prizes were awarded to the top three winners of the hackathon, with the Grand Prize of USD 100,000 for first place, USD 80,000 for second place and USD 50,000 for third place.
      Grand Prize Winner: The Quest of Sunflower by Couchplay
      An epic adventure game based on an AI-generated story, featuring stunning graphics, immersive audio and responsive game play suitable for the whole family.
      Second place: Signs of Magic by Lukas Klingsbo
      Set in a magical world, this game follows the wizard Elowen as she battles invading creatures known as Astromentals. It integrates LG Magic Remote sensors to create an immersive experience that brings the action to life.
      Third place: Thormdeil: Into the Unknown by TV Games
      The first single-player RPG developed exclusively for a Smart TV platform, featuring seasonally AI-generated content. Players navigate dark dungeons, face survival challenges and uncover hidden truths.
      “The amount of participation and entries we received this year is proof of the growing interest in the AI and gaming categories,” said Chris Jo, senior vice president of platform business at LG Home Entertainment Company. “We’re no longer simply watching television. The developer ecosystem’s role in improving the lives of millions of consumers in their homes is exponential, and LG plans to hold this event annually to foster webOS app developer ecosystem.”
