Description
An issue was discovered on Libre Wireless LS9 LS1.5/p7040 devices. There is Unauthenticated Root ADB Access Over TCP. The LS9 web interface provides functionality to access ADB over TCP.

As such, any unauthenticated user who is able to access the web interface will be able to gain root privileges on the LS9 module.
