Date: Thu, 28 May 2015 10:31:31 -0500 From: Zach C <uid000@...il.com> To: fulldisclosure@...lists.org Subject: [FD] Broken, Abandoned, and Forgotten Code, Part 6 Part 6 is live! We continue reversing the undocumented Netgear firmware header by debugging the embedded HTTP server. We identify two more fields, including an unknown checksum. A disassembly-to-python reimplementation of the checksum algorithm is provided in this week's update to the example code. Here's a link: http://shadow-file.blogspot.com/2015/05/abandoned-part-06.html I forgot to include the link to part 5 in last week's message (whoops!): http://shadow-file.blogspot.com/2015/05/abandoned-part-05.html The goal remains to reverse engineer the firmware format so we can generate a malicious firmware image to use 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://seclists.org/fulldisclosure/2015/May/44 As always I welcome feedback via email or Twitter. I'm @zcutlip. I hope you enjoy it!
