New exploit for webOS 3.5+: DejaVuln (2024-04-21)

See dejavuln-autoroot for a simpler exploit that works on webOS 3.5+ TVs (i.e., models from 2017 and later). It is unpatched as of 2024-04-21 and does not require Developer Mode or even a network connection—just a USB drive.

Otherwise:

• If you have a webOS 5–8 TV with old enough firmware, WTA (which does not require Dev Mode) will still work.
• If you have a webOS 4.x TV, you can also try CVE-2023-6319, which is unpatched on the latest (final?) firmware for webOS 4.0 (2018) models.
• While there will eventually be fully software-based exploits released for older models, they can currently be rooted via NVM.

This is a simple guide on how to automate UK lights with a Shelly 1 by installing the shelly 1 relay into the ceiling pendant which has both permanent live, neutral and a switched live back from the wall switch.

These steps are from my own experience making my lighting "smart" but also user friendly (it works via a wall switch!). This simple guide will go through replacing an a normal ceiling pendant with one with room for a Shelly 1. If you have a ceiling light with a bigger base it's even easier.

Warning Electrical regulations must be followed by law. If you are not a competent person under the regulations do not attempt electrical work. https://www.diydoctor.org.uk/projects/electrical_safety.htm

Wiring Diagram

This diagram has been taken from here and modified to include the Shelly 1.

This is handy for seeing the couchdb futon interface without making it publicly available. It still will only accept connections from localhost.

Syntax:
ssh -L <local port>:porxy:<remote port> <user>@<remote host>

Example for CouchDB:

ssh -L 5984:localhost:5984 ubuntu@10.0.99.115
