Part 7 is up! We further refine the undocumented firmware header for the Netgear R6200 SOHO router. A couple of additional checksum and size fields are added as well as a packed version string field. http://ift.tt/1FWHnBI Only 5 bytes in the 58 byte header remain unidentified, which is sufficient for the web interface to happily accept our custom firmware image. Of course we haven't started customizing the contents of the firmware yet; that will come in a later post. We'll need to generate customized firmware for use as a payload when exploiting the SetFirmware SOAP action described in parts 1-4. If you missed my post to Full Disclosure where I introduced the series, here's that: http://ift.tt/1F6IUWA As always I welcome feedback via email or Twitter. I'm @zcutlip. I hope you enjoy it! Cheers, Zach
