FWIW: I didn't produce the content presented here (the outline from Edmond Lau's book). I've just copy-pasted it from somewhere over the Internet, but I cannot remember what exactly the original source is. I was also not able to find the author's name, so I cannot give him/her the proper credits.

Netgear TLS Private Key Disclosure through Device Firmware Images

Netgear Signed TLS Cert Private Key Disclosure

Overview

There are at least two valid, signed TLS certificates that are bundled with publicly available Netgear device firmware.

These certificates are trusted by browsers on all platforms, but will surely be added to revocation lists shortly.

The firmware images that contained these certificates along with their private keys were publicly available for download through Netgear's support website, without authentication; thus anyone in the world could have retrieved these keys.
