###  Device Details
Discovered By: Andrew Klaus (andrew@...aus.ca)
Vendor: Actiontec (Telus Branded)
Model: WEB6000Q
Affected Firmware: 1.1.02.22

Reported: July 2018
CVE: CVE-2018-15557

### Summary of Findings

Two instances of Linux run on the WEB6000Q. One is the “main” instance
that runs the web management server, TR-069 daemon, etc., while the
other is the "quantenna" management OS used to manage the wireless.

By hardcoding an IP address in the 169.254.1.0/24 network, and being on
the same layer 2 network, root telnet access can be obtained on the
"quantenna" management environment by accessing:

Host: 169.254.1.2
Port: 23
Login: root  (no password prompted)
