A simple python script that starts a telnet server on vulnerable webOS devices as root.

• webOS 4.9.7 - 5.30.40 (model LG43UM7000PLA)
• webOS 5.5.0 - 04.50.51 (model OLED55CXPUA)
• webOS 6.3.3-442 (kisscurl-kinglake) - 03.36.50 (model OLED48C1PUB)
• webOS 7.3.1-43 (mullet-mebin) - 03.33.85 (model OLED55A23LA)

1. Install Python 3 from https://www.python.org/downloads/ or using a package manager
2. Clone this repo
3. Install dependencies using pip install -r requirements.txt
4. Run the script using python rootmytv.py
5. Follow on-screen instructions

If the script was successful, a telnet server with root access will be created on the TV with port 23. You can use any software to access it, for example Putty on Windows.

• 500 application error, not allowed to call com.webos.service.downloadmanager/download: your TV is patched against this vulnerability and is thus incompatible
• websockets.exceptions.InvalidMessage: did not receive a valid HTTP response: you are using an old version of the script, please redownload all files, reinstall the requirements and try again

This exploit uses the following CVE: https://www.cve.org/CVERecord?id=CVE-2023-6319
