Hopefully you will never have to refer to this tutorial, but for people who like to play with their routers, it sometimes happens -- you accidentally "brick" your router. This tutorial enables you to recover your router by flashing stock firmware back again using serial console and windows PC. Developers who want to get access to their router by using a serial console may also refer to this tutorial.

The Heartbleed vulnerability allows an attacker to read random 64k blocks of memory of the service using OpenSSL (with TLS). Since every request delivers another 64k memory block an attacker could retrieve sensitive data from the service i.e. private keys. More detailed information about Heartbleed can be found in the security advisory:

This vulnerability is only if running the following services are using OpenSSL with TLS:

Via: DD-WRT

The Heartbleed vulnerability in discovered in OpenSSL 1.0.1 - 1.0.1f is one of the most serious matters in encrypted data communication during the last years. First of all we can ensure you that the encrypted web services like the DD-WRT Online Shop and the Activation center never have been affected because the OpenSSL version we are using does not contain the vulnerability.

Introduction:

Using serial console setup users can get access to the serial console of their router. Serial console setup finds its most important use in debricking a router. Moreover, developers may use it to extract useful debug information from their routers.

This short tutorial explains how to setup serial console for Netgear R6200v2.

This tutorial guides users to install firmware into their Broadcom(BRCM) based Netgear router from a linux machine, using USB-TTL cable.
