    Security Advisory for Linksys Smart Wi-Fi series of routers


    Posted: 20 Apr 2017

    Overview

    Linksys was recently notified of some vulnerabilities in our Linksys Smart Wi-Fi series of routers. As we work towards publishing firmware updates, as a temporary fix, we recommend that customers using Guest Networks on any of the affected products below temporarily disable this feature to avoid any attempts at malicious activity.

    Description

    IOActive (www.ioactive.com), a global cybersecurity consultancy, responsibly disclosed to Linksys that they had discovered vulnerabilities affecting multiple Linksys routers. The Linksys Security team has been working with IOActive to confirm and resolve all reported issues. We will be releasing firmware updates for all affected devices. In order for your device to receive the update as soon as it is available, please make sure you have automatic updates enabled:

    Solution

    We are working to provide a firmware update for all affected devices. While we are building and testing the fixes we recommend performing the following steps:

    1) Enable Automatic Updates. Linksys Smart Wi-Fi devices include a feature to automatically update the firmware when new versions are available.

    Oh no I've made the list. I have the EA2700. I always run the router the same as the 3 solutions, so it's up to them to get busy writing updates.
    Thanks much for the heads up Brink. I will post back if and when there is any progress on patching this.

    Thanks @Brink, just checked them yesterday. No update for my EA2700. I guess they're not going to update it. It's from 2014. A shame because it works just great.
