"Linksys takes the security of our products and customers’ home networks very seriously. Although we can confirm contact with DefenseCode, we have no new vulnerability information to share with customers – for our WRT54GL or other home routers. We will continue to review new information that comes to light and will provide customer updates as appropriate."Cisco has responded, according to Net-Security:
After the researchers posted their findings online, Cisco finally got in touch again. They are expected to release a fix in time for the full advisory, which should see the light of day in about 10 days.There is a vulnerability, a patch is coming, and everyone knows about it.
