Mudi (GL-E750 v2) and Tailscale security issue

Technical Support for Routers
1

I installed Tailscale from the plugins directory (it's really, really weird that such a new device does not have this plugin built in, not does it have any GUI).

I found at the end that in order to use Tailscale, I'll need to do it through SSH, which I did, and it works.

However, the version that is available with Mudi (with the latest update) is 1.32.3-1 which has security issue and Tailscale requires to immediately upgrade to 1.74, which I cannot find for my device.

Will this issue be addressed in an upcoming firmware? (I've seen somewhere else a script to update Tailscale, but this version only crashes with "illegal instructions" on the Mudi)

Thanks

E750v2 does not support the Tailscale plugins in the GL firmware, since it could not perform due to the hardware

I use Mudi E750 V1 with tailscale and update manually, as follows;

  1. SSH into Mudi (I use WinSCP for this) and navigate to the folder /usr/sbin. There are two files here that must be replaced, tailscale and tailscaled.
  2. Confirm your CPU architecture (Mudi/E750V1 is MIPS) by running the following command:
    root@GL-E750:~# cat /proc/cpuinfo
  3. Download the latest file from https://pkgs.tailscale.com/stable/#static . For Mudi these are in the Static binaries (other distros) section, the one you need for Mudi E750 V1 is "mips"
  4. Replace the two old files in folder /usr/sbin with the two new files from the latest mips binary.
  5. Change the new file permissions to match the old file permissions. Correct permissions are: rwxr-xr-x
  6. Start tailscale by command:
    root@GL-E750:/usr/sbin# tailscale up

This has worked for me and I hope it helps.
