July 21, 2014, 1:58 PM — Advocacy group the Electronic Frontier Foundation wants to address the poor security track record of home routers with a new firmware project that will encourage users to share their Internet connection publicly by setting up guest Wi-Fi networks.
The first experimental version of the firmware, called the Open Wireless Router was released Sunday and is mainly aimed at developers and hackers who can assist with finding bugs and improving the software overall.
The project's main goals are focused on allowing router owners to securely set up public Wi-Fi networks for passers-by to use, which the EFF and other organizations argue helps conserve radio spectrum, benefits business and economic development and can spark innovation. However, some of the firmware's other planned features could also improve the overall security of routers that run it, even if their owners don't decide to share their Internet bandwidth with strangers.
"Most or all existing router software is full of XSS [cross-site scripting] and CSRF [cross-site request forgery] vulnerabilities, and we want to change that," the EFF said Sunday in a blog post.
While this is generally true, the XSS and CSRF flaws, which allow attackers to hijack authenticated sessions, are actually among the least critical flaws commonly found in routers.
Over the years security researchers found vulnerabilities in routers that would have given attackers full control over many devices from a large number of manufacturers. The issues found included backdoor-like features and hard-coded credentials, traditional buffer overflows and command injection vulnerabilities in the Web-based administrative interfaces or even implementation errors in third-party components like UPnP libraries.
The overall consensus among security researchers is that from a security perspective the code maturity in the home router world is very poor. Adding to that problem is the fact that few router vendors publish detailed security advisories and that updating the firmware is usually a process that requires manual intervention and technical knowledge from users.
The Open Wireless Router firmware will have an automatic update mechanism that will work over HTTPS and will use digital signatures to prevent upstream tampering with the updates, the EFF said. "Firmware signatures and metadata are fetched via Tor to make targeted update attacks very difficult."
