Quantenna · Quantenna Wifi Controller · CVE-2018-15557
**Name of the Vulnerable Software and Affected Versions**
Telus Actiontec WEB6000Q version 1.1.02.22
**Description**
An issue was discovered in the Quantenna WiFi Controller on Telus Actiontec WEB6000Q devices. An attacker can statically set their IP to anything on the 169.254.1.0/24 subnet and obtain root access by connecting to `169.254.1.2` port 23 with `telnet` or `netcat`.
**Recommendations**
For version 1.1.02.22, as a temporary workaround, consider disabling access to port 23 to minimize the risk of exploitation. Restrict access to the `169.254.1.0/24` subnet to prevent unauthorized connections. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
